Crosman 1077

The Crosman 1077 CO2 powered air rifle comes in 2 main flavors; the RepeatAir 1077 and the AirSource 1077. If you are an air rifle enthusiast, you really can’t go wrong with this very popular and powerful model which features semi-automatic operation, a quality that is quite rare. Let’s review the base model in detail.

The RepeatAir is the base model, but still shares all the main features of the uprated AirSource and will also accept all the same accessories. The RepeatAir Crosman 1077 is a .177 caliber air rifle and measures around 37 inches in length. It weighs in at 3lbs 7 ozs and most people report it as ‘feeling substantial’ in feel and hold, but at the same time it’s actually lightweight. In fact it’s often a pound or two lighter than many pump, pcp or break barrel pellet guns. Although it has a wood-like color, it’s actually made of all-weather synthetic stock. The designers state that this ‘assures years of rugged wear and tear that will keep your 1077 looking good as long as you own it’. Well certainly looking at many reports, videos and the like, no-one has yet reported any issues with the material, so that’s good.

The base model is powered by CO2 in the shape of a 12g powerlet cartridge, which is simply inserted into the body of the rifle. It’s good for around 50 – 80 shots, many people getting towards the upper end of those figures. This is fine for most situations as it doesn’t constantly interrupt the fun. Fitting a new cartridge takes just a minute or so, but don’t forget to place a single drop of oil on the tip of the powerlet.

What Makes the Crosman 1077 So Popular?

Let’s get down to the real stuff. It can fire the ammo as fast as you can pull the trigger! It’s rated at 625fps (feet per second), but I’ve noticed a number of users reporting getting higher ratings than this, mainly based upon the type of air pellet used. So it’s worth trying out a number of different types of pellets to find what works best for you. There’s no point in advising the best pellet as it depends very much on what you intend using the gun for and your particular experience with any pellet type and brand. Some users report different experiences using the same type/brand of pellet, so it’s definitely worth experimenting.

The Crosman RepeatAir 1077 comes with a drop-out magazine into which you insert the 12-shot rotary clip. It’s quite satisfying to snap in a magazine and start firing off multiple rounds! You get supplied with two 12-shot clips into which you pre-load the pellets. Almost everyone reports that it’s much better to also buy the SpeedLoader kit which gives you an additional three 12-shot clips, making for a much better shooting experience in the field or in the back-yard. For under $8 it’s also a no-brainer.

As far as sighting goes, the rifle comes with a CenterPoint™ fiber optic sight at the front of the barrel, with a rear sight that is adjustable for windage and elevation. Again, most people report great accuracy in the 75 – 100 feet range, some stating they can group shots within an inch at those distances. It’s great to see that so many have reported accuracy, considering the relatively low cost of this rifle. You can get a scope for this rifle to get even more accuracy. The 1077 offers a lot of flexibility.

I don’t believe the RepeatAir Crosman 1077 comes with any 12g CO2 cartridges (unless they’ve changed what is packaged), but you’ll need to order some more anyway, so make sure you do that at the same time as ordering the gun – nothing worse than wanting to rush out to the backyard only to find you don’t have a means of firing!

Overall the Crosman 1077 is a great buy for target shooting, plinking and for small pest control. A number of users report taking out small rodents up to squirrel size. Rabbits can be attempted, but you’ll need pellets with good penetration for that. This is a pretty quiet rifle so that’s good on two counts. If you use it in your backyard and have neighbors, they will be unlikely to complain. If you use it in the field, you’ll be less likely to scare off any wildlife. Of course, if you miss and the wildlife makes a run for it, you’ll be able to fire off another rapid 11 shots won’t you!

The Air Source Adaptor is a popular accessory item from Crosman, and the Crosman pack comes with one 88 gram CO2 cylinder and the adaptor itself.

Let’s be clear about what this adaptor is for though first since there is a lot of confusion out there as to it’s uses.

First of all, the Air Source Adaptor is for adapting a Crosman 88 gram CO2 canister to a paintball marker.

Contrary to popular belief, these adaptors are NOT made for refilling the CO2 cartridge for use say on an Air Source Crosman 1077. The CO2 itself is clearly marked with the following:  “Do not refil this cylinder – One time use only”. You’ll probably also find that many people with refill services will refuse to refill these cylinders for liability reasons, including the fact these cylinders don’t have any anti-burst features.

The adapter is only for use on the cylinder on a paintball gun by converting the threads and punching the seal on the bottle.

So if that’s what you want it for, here’s the link:

Air guns come in two forms, the air rifle and the air pistol. As the name suggests, both drive their projectiles with the use of air, but the air is compressed in one way or another.

Historically, the air gun certainly existed in one form in the 16th century as there is a surviving example in the Stockholm museum! By the 17th century, air guns had developed enough to be used in hunting. All these examples were usually in the form of air rifles, and by this time they were developed enough to be able to penetrate 1 inch thick wood at a distance of 100 paces. Pretty impressive even for today!

The pressures attained on a range of these guns amounted to some 800PSI which was pretty amazing. Today however, we are limited to low pressure purely for safety and legal reasons. In fact in some countries, air guns are still classified as firearms, so you wouldn’t be able to buy or use one unless you had a license.

Power To The Air Gun

Nowadays we have a choice of types of air gun. By that I mean the choice of how we power that gun. It’s still principally driven by air, but the method of how that air is compressed varies significantly.Let’s look briefly at each of the options and see what advantages or disadvantages each offer.

CO2 Air Guns

Much like the Crosman 1077 rifle described elsewhere, these type of guns are driven by CO2. The CO2 is stored in either small 12g caplets, or containers, or in larger 88g containers. Both are fitted to the rifle. The smaller caplets offer around 50 – 80 shots before you need to replace, whilst the larger CO2 cylinder gives a huge 300 – 400 shots! Clearly, the biggest advantage of this method is the continuity of fun! You’re not constantly stopping to re-charge the gun, and if you’re hunting small vermin, this is pretty essential as you won’t have time to re-pump and aim at a critter as it’s likely they’ll be a long way off by that time! The downside is that you have to pay for the CO2.

Break Barrel Gun

As the name implies, you ‘break’ the barrel at the point where it is hinged, in order to compress a steel spring which is hidden away inside the gun. The advantage of this gun is that the air is ‘free’. All that is required is a but of muscle power to compress the spring. Some air rifles require quite a bit of muscle power and that is one of the disadvantages of this type of gun. The other disadvantage is the time taken between each shot. Not so bad if you’re just plinking, but a disaster if you’re vermin hunting and scare the thing off with your first missed shot! Some makes of gun use a ‘gas spring’ instead of a coiled steel spring. Some brands which use of this are Weirauch, Crosman and Arowsmith.

Pneumatic Gun

This is where you use pre-compressed air as the source to fire the pellet. Compression is achieved by priming a lever somewhere on the gun. The pneumatic gun includes a few variants. These are:

• single stroke – where you only need to prime the pump once on the gun for it to be ready to fire
• multi stroke – where you need to prime the pump lever around 2 to 10 times to achieve variable power
• pre charged pneumatic (PCP) – where you charge the reservoir not from a lever fitted to the gun, but from an air reservoir such as a diving cylinder or even a hand pump

Like the CO2 air guns, these offer an advantage where you want uninterrupted shooting, as you can achieve up to around 500 shots on a good reservoir. The disadvantage is usually the higher cost of acquisition since the production of these types of gun is costlier. In addition, you have to buy a decent high pressure hand pump or a diving cylinder. Usage costs will be lower though than say a CO2 gun.

So there you have it. A brief synopsis of air guns and an outline of their relevant good and bad points. I hope it helps any choices you need to make when considering an air rifle or air pistol.

You know the Crosman 1077 combo has become one of America’s most popular air gun choices, and for good reason. It’s a versatile air rifle, packs a good punch at 625fps, and is pretty accurate.

Many thousands have been bought across the US alone, and most of these owners still use their gun, even after years of ownership. That speaks volumes. Let’s now look at one of the options for the popular Crosman 1077 model, the combo.

What Does the Crosman 1077 Combo Offer For the Money?

The combo consists of two main components, the air rifle itself, and the scope. For a long time, Crosman itself has not decided to bundle the two together and offer a ‘combo’ package, for its own reasons, whatever they are. Although it is fair to say they obviously offer the rifle and a whole array of scopes that will fit on the 1077. No, the idea of putting the two together seems to have come from independant sales companies who believe the end user wants this type of bundle and usually offers the two at an attractive price.

Crosman 1077 Combo

So what spec does a typical Crosman 1077 combo offer? Well the most popular option seems to be targeting the ‘good value’ end of the market, selecting a good scope but without the high-end price to go with it. For example the typical set-up includes the RepeatAir 1077 rifle plus CenterPoint 4×32 scope. The RepeatAir model is the version using the 12g CO2 capsules, and is a .177 caliber, the same as all other 1077 models. The CO2 simply slips into the stock underneath the barrel, making for an easy and quick operation. Again, as with other 1077 models, this combo version comes with a magazine loader for your 12-shot clip. The rifle is a semi-automatic, a pretty unique feature on a rifle in this range. In fact you can fire off 12 pellets as fast as you can pull the trigger, it’s that good. Many users report getting 50 – 80 shots from each CO2 cartridge before having to replace it, so that’s not bad.

The CenterPoint scope is also made by Crosman. It has easily adjustable windage and elevation dials, a one-piece tube construction and is 100% waterproof, fogproof and shockproof to protect it when you’re outdoors. It has good feedback from a number of users. Its full specs are:

Crosman 1077 Scope Specifications

It’s great fun to use, an excellent trainer if this is your first air rifle, affordable, and with the value add-on scope, can be very accurate.  It is light to carry and hold, very easy to load using the SpeedLoader option and magazine and has a good trigger action. Don’t forget, it will also accept all the other Crosman air rifle accessories.

So if you don’t hit the target in the right place the first time with this rifle, you just pull the trigger again – and again! There’s no barrel breaking, pumping or cocking to do, so shooting is fast and easy and you can just concentrate on the fun bit. Just sight your Crosman 1077 combo and pull for great target practice or small vermin extermination.

In recent years, the telescopic Crosman sight (referred to as a scope) has become very popular, even on airguns. There are a number of Crosman sights available, including several Crosman models available as a combination consisting of the rifle and scope. So the scope can be used on the Crosman 1077, including the Crosman AirSource 1077 and Crosman RepeatAir 1077.

A scope sight has many advantages. First, the scope magnifies the target so you can see it better, and it has an aiming device such as a crosshair (the reticule) that can be aligned easily on the target. Second, scope sights are designed so that the reticule and the target appear to be the same distance away. Therefore, it is not necessary to focus your eye on the rear sight, front sight, and target (which is not possible) which are at differences from you eye.

Adjusting Crosman Scopes

In addition to the advantages described above, scopes are easy to adjust to sight in an air rifle. Adjustment knobs are located near the middle of the scope on the turret. One knob adjusts elevation while the other adjusts windage. The sight in procedure is the same as that described above except that the scope adjustment knobs are clearly marked as to which direction to turn them to achieve a desired change in the point of impact. Moreover, scope knobs have a scale that shows how much the point of impact is moved for each ‘click’ the knob is moved.

Although telescopic scopes make it much easier to shoot accurately, they alter the handling characteristics of the rifle. Also, a scope adds weight to the rifle and makes it larger which can be a factor in some instances. Even with these minor disadvantages, the use of scopes on airguns has become so common that several manufacturers of scopes make models specifically for use on airguns.

Red Dot Sights

In recent years, two other types of optical sights have become popular. The first of these is the red dot sight which is so named because it makes use of a red dot projected on a lens. The dot can then be aligned on a target by looking through the sight and moving the gun so that the red dot is placed correctly on the target. A red dot sight requires aligning only two objects, the dot and the target. Red dot sights are easy and fast to use, but they are not normally employed when high accuracy is desired. In most red dot sights, the dot is large enough so that it covers an area that is as much as 2 or 3 inches in diameter at 25 yards so precise aiming (as with a scope) is not possible. After the red dot sight is mounted on the gun, it is sighted in in much the same manner as a scope.

Laser Sights

The second type of sight to see common usage is the laser sight. A laser sight consists of a laser that is mounted on the airgun similar to the way in which a scope is attached. It emits a laser beam that is directed toward the target. When the beam is on the target, the shot fired should hit where the beam is directed if the sight is properly adjusted. Laser sights are adjustable for elevation and windage by means of screws that move the laser beam in the direction needed to make the point of impact coincide with the point of aim. Although the laser sight is an interesting device, it is somewhat limited in its ability to be used in bright light and at longer distances. Also, the beam has enough width to make it a less accurate aiming device than a scope. Because they are more suitable for rapid target acquisition at short ranges, red dot and laser sights are more often used on handguns than on rifles. So there you have it, amongst the Crosman air rifle accessories we’ve given you Crosman sights in a nutshell. We hope that was of some use.

Crosman air rifle accessories, such as for the 1077, come in a limited, but useful range.

Let’s look at what is supplied with the latter range first, as that will often dictate what people will buy first, as well as purchasing additional items such as pellets, silencer, scope, adaptors etc.

At the time of writing, a Crosman air rifle will come with one magazine for loading the 12-shot rotary clip, and usually two 12-shot rotary clips themselves. There’s a tube of Pellgunoil, and in the case of the RepeatAir 1077, a 12g CO2 cartridge. So one of the first things you will need is some air rifle pellets. Now these come in a range of styles, brands and weights, as well as prices. To be honest, there is often a wide range of variation of performance with air gun pellets, so there’s no single brand or type that can be recommended with certainty.

Generally speaking, paying more will often get you a better fps speed, better accuracy or better penetration, again depending on what type you buy. That’s not always the case however. The rule is to experiment as much as you can. There are packs of pellets that come with 4 or more different pellet types, I think Gamo is one of the brands. Start with this and see how each pellet

performs. Also buy a relatively expensive pack of pellets, and see how they compare. It’s clear from feedback that each persons experience can vary significantly, and each swear by their own. So make your own choices based on your own experiences, not someone else’s.

It’s not cheap buying a pack of this and a pack of that just to find out which pellet works best. However, we’ve managed to source one pack, made by Gamo, who supply a range of 4 different pellet types – Master Point, Match, Magnum and Hunter – in one pack. A good number of people have given this pack a 5-star rating, not just for having a good range of pellet types to try but also the fact that’s it’s a bargain deal containing 1,000 pellets. You can read more on this, or to buy, using the link on the left here.

Talking of air gun pellets, let’s not forget the 12-shot rotary clips. Whilst you do get provided with two of these, it’s clear that many people order the SpeedLoader kit which gives you an additional three rotary clips. The name by the way, is not to be confused with a faster way of loading, it means you don’t have to spend time fitting pellets into the rotary clip if you’ve got a number of them pre-filled with pellets. In other words with one kit, you will have a total of five rotary clips, giving you a grand sum of 60 pellets to fire off before you have to stop and refill the clips. Of course, at under $8, it’s easily tempting to just buy a few kits and not spend any time refilling clips at all!

Next is the CO2 cartridges. Buy Crosman CO2 cartridges, since this is a Crosman gun. Other brands may have slight tolerances that mean you will experience leaks. That will mean you’ll get short-lived cartridges, and worse still, much poorer distance and accuracy. One of the biggest complaints on forums and similar sites is ‘the CO2 cartridge leaks’. I suspect some of these may be due to poor quality cartridges, but many may be over-tightening of the cartridge to the gun fitting. You don’t need to over-tighten since the seal will do the job for you.

Click above for pack options

Packs of CO2 cartridges come in, well they come in virtually any number you want! I’ve seen packs of 1, 2, 3, 5, 10, 15, 25, 40, 50 or 100. Did I leave any number out? This is going to be nice and simple – buy more cartridges, pay less per cartridge! Nuff said.

Now for the AirSource 1077, there is the 88g CO2 cartridge. Again, at the time of writing this is not supplied as part of the package, so you’ll need to get some in. As with the 12g CO2 cartridge above, you can get them in various pack sizes along with increasing discount. If you search a few forums, you’ll find some gun owners have made their own adaptors and re-fill the cylinder themselves. I’ll leave you to research that one as it’s outside the scope of this review.

Outside of these basic gun accessories, come the more esoteric stuff such as the scope. This fits on to the Crosman rifle via the 11mm dovetail on top of the barrel. There’s a whole range of scopes that can be fitted to this gun, from a simple 4×32 to more sophisticated units with various options. A CenterPoint scope is a popular fitting and is made specifically for Crosman.

That wraps up the Crosman air rifle accessories for the 1077 air rifle. Limited, but all you’ll need.

This has got to be one of the most fun air rifles to use and shoot. The AirSource 1077 is exactly the same as the base model described earlier above, with one main exception; the CO2 cartridge. This comes in the form of a much bigger 88g cartridge which is fitted to the rifle with an adaptor. This allows for a much bigger range of shots on one charge, usually accounting for around 300 – 400 shots. Of course you’ll also get much more consistent power over that range, giving you a better experience.

Once again, Crosman have provided the goods with this great 12-shot rotary clip that just plugs into the magazine, styled after a military carbine. One snap into the rifle body and you’re blazing away as fast as you can press that trigger. The package comes with two 12-shot clips, but my advice is to order the Speed Loader kit which gives you another 3 clips. That means you can load up 60 pellets beforehand and just get on with the fun part! For the price, (you can find these kits at a maximum of $8, and I’ve even seen some below $5), you could get real mean and buy a whole batch. Watch those pellets spray!

Perhaps surprisingly for a gun in this price range, the steel barrel is rifled. That’s certainly a welcome feature and aids its speed and accuracy. For even greater accuracy, you can mount a scope on the 11mm dovetails that are placed on the top in the usual position. A simple 4×32 scope comes very cheap these days but there are many more sophisticated ones if you want to get fancy.

Final Thoughts on the AirSource 1077

To get the best performance for your rifle, always keep the barrel and other components clean. This simple duty will not only extend the life of your gun, but perhaps more importantly, keep it accurate and maintain the barrel velocity. Use something like Crosman Pellgunoil which only costs around $6 or less and will last quite a time.

The Crosman AirSource 1077 package comes with rifle, trigger safety lock, magazine, two 12-shot clips and one 88g CO2 cartridge. As with the pellets mentioned above, getting in a few more CO2 cartridges won’t go amiss and will keep you going for a while. Buying in bulk will always bring the price down of course, but your choice.
