Crosman 1077 CO2 Review


The Crosman 1077 semi-automatic CO2 air rifle is designed with inspiration from a Ruger 1022 firearm.

If you look at online customer ratings, you can see lots of positive reviews and plenty of negative reviews.

What the heck is happening, you say?

Don’t worry, I guarantee you will find the answer to that phenomenon at the end of this Crosman 1077 review.

Crosman 1077 semi-automatic – Gun Type

This air rifle is a CO2 pneumatic air gun.

Unlike the spring gun that uses a coiled spring as the powerplant, a CO2 gun’s power comes from compressed air in a CO2 cartridge.

CO2 guns are extremely easy to cock, highly accurate, convenient for repeated shooting, and can allow semi-automatic firing.

The Crosman 1077 has a multi-shot capacity with a 12-shot rotary pellet clip.

When you pull the trigger, the clip rotates around its axis, so there’s a pellet reloaded every time.

Multi-shot ability permits you to enjoy more shooting and more fun over a long period of time.

The barrel of the Crosman 1077 air gun is a rifled steel barrel with spiral grooves inside.

(For more on things you should know about air rifle barrels before buying, see this post.)

The Crosman 1077 air gun is a semi-automatic rifle.

Don’t confuse semi-automatic with automatic guns.

Automatic guns allow you to fire continuously as long as you keep holding the trigger.

The gun keeps firing until the magazine is empty.

On the contrary, a semi-automatic gun requires you to pull the trigger separately.

After you shoot the first shot, the trigger must be reset in order to fire the next round.

Nonetheless, the Crosman 1077 allows you to fire as fast as you can pull the trigger.

The faster your finger movement, the more pellets you fire.

This semi-automatic feature increases follow-up shot speed and gives you the ability to shoot the entire slip without readjusting the sight.

Crosman 1077 Stock

The Crosman 1077 has an all-weather synthetic stock.

(For more on the in-depth comparison between synthetic and wood stock, see this post.)

The Crosman 1077 air gun has a plastic buttpad to absorb recoil and help you enjoy more shooting without worrying about hurting your arms.

Besides, it features non-slip checkering in the grip and forearm.

The checkerings increase friction between the shooter’s palm and the gun’s stock, add more stability to your arm when shooting, and prevent slippage from the shooter’s sweat.

Crosman 1077 has the .177 caliber (the internal diameter of the barrel, measured in inches) so it uses .177 pellets as ammo.

.177 pellet is cheap and lightweight.

It also has various types such as wadcutter, round nose, pointed, hollow point, etc.

(For more on the differences between .177 & .22 and which jobs they do best, see this post.)

Crosman 1077 velocity, power and accuracy

79 Crosman 1077 CO2 Review

The maximum velocity of the Crosman 1077 air gun is 625 FPS (feet per second).

It’s medium speed compared to other guns.

You can shoot about 50 shots per CO2 cartridge before having to reload another CO2 canister.

With Crosman 7.9 premier match wadcutter pellet, the average velocity is 590 FPS.

The average result with Crosman pointed pellets is 601 FPS.

It is recommended that pellets produced by Crosman Corporation achieve the best performance.

For Crosman 1077, various shooting tests have been conducted by different shooters with positive results.

The common shooting groups are:

1/2” at 40 feet,

1” at 30 feet,

1/2” at 20 feet,

3/4” at 20 feet,

2.5” at 35 feet, and so on.

Some people even manage to get a 1.5” group at 15 yards, 1/4” at 25 yards, and 1” at 25 yards.

To sum up, this gun is extremely accurate up to 25 yards of distance.

Paul Capello, from Airgun Reporter, examined the Crosman 1077 air rifle here:

Loading Crosman 1077 CO2 air gun

Loading the pellet:

First, put the gun on “SAFE”.

Press the release buttons on both sides of the magazine and pull it downward.

Slide the pellet clip pin forward and take out the clip.

With the clip in one hand, use your other hand to insert a pellet at one of twelve pellet chambers (with the pellet’s nose lying forward and the pellet’s skirt flying backward).

Keep inserting the pellet until the clip is full.

Put the clip into the magazine, pull the clip pin rearward, and return the magazine to the stock.

103 Crosman 1077 CO2 Review

Installing CO2 cartridge:

Put the gun “SAFE”.

Unscrew the piercing tube cap below the barrel and remove it.

Insert the new CO2 cylinder into the gun with the small head pointing rearward.

Screw the cap firmly into place.

Put the gun off safe and fire.

If the gun doesn’t shoot, put it on safe and tighten the screw more (you can use a screwdriver or a coin placing in a slot of the knob to produce more force)

In summary, you can see that it takes very little effort to load the Crosman 1077 gun.

And the best part is you don’t have to break a single sweat to pump or to break down the barrel like other pneumatic rifles and springers.

Crosman 1077 Sight

The Crosman 1077 has a fiber optic front sight.

The sight uses optical fiber for the dots so you could align the target faster and more accurately, even in the low-light shooting condition.

Besides, the rear sight has windage adjustment (allows you to adjust the sight left and right), and elevation adjustment (allows you to adjust the sight up and down).

(For more on how many types of air gun sights are out there and which one is suitable for you, see this post.)


The Crosman 1077 is very quiet.

It has hundreds of customer reviews without a single complaint about noise.

You don’t have to buy hearing equipment even if you have sensitive ears.

Moreover, you can be confident to shoot this gun in the backyard without disturbing your neighbors.

Shooting range and intended use

The Crosman 1077 CO2 air rifle is great for target shooting and plinking up to 30 yards.

It’s not recommended to use this gun for pest control or small game hunting unless in the close range (less than 20 yards)

Crosman 1077 Accessories

The Crosman 1077 has CO2 cartridges as the only accessory.

You can buy a speed loader and an additional pellet clip for a faster reload.

For even greater accuracy, you can buy a scope to mount in an 11mm dovetail scope rail.


The Crosman 1077 semi-automatic air gun requires very little maintenance.

You only need to put a drop of Pellgun Oil on the tip of every CO2 cartridge, another drop on the thread of piercing tube cap, and a light coat of oil on the barrel to prevent rust.

As you can see above, the barrel is not very long and the gun only weighs a little more than 3lbs

Crosman 1077 Price

72 Crosman 1077 CO2 Review

The Crosman 1077 price is only $70.

You can’t get a better semi-automatic CO2 air rifle at this price level.

Also remember that if you shoot a lot, you should buy numerous pellets (500-count packs at least) and a bunch of CO2 cartridges.

The cost of CO2 capsules and pellets can add up over time, though.


As of this date, the Crosman 1077 semi-automatic CO2 air rifle has a one-year limited warranty from the date of purchase.

Customer Reviews

While researching this product, I always look at the trench in customer reviews.

Although the Crosman 1077 has lots of 4 stars and 5 stars, it also got a bunch of 1-star ratings.

There are 2 issues that arose with the negative reviews:

The first is the problem of leaking CO2 so the gun cannot shoot at all.

But defective products are a risk we always have to face in online buying and air rifle shopping is no exception.

The second is the pellet jamming.

The manual is very clear about how to insert the pellet into the clip properly so make sure you follow the instruction carefully to avoid this problem.

Besides, it is advised that you use only the Crosman pellet to work with the gun to get the best result and avoid any potential damage to your gun.


Crosman 1077 is one of the best CO2 air rifles for the money.

It’s lightweight, durable, reliable, easy to handle, highly accurate, easy to sight in, and very cheap.

It’s a great gun for kids, female shooters, seniors, and the young at heart.

I highly recommend it for shooters who want to practice target shooting and plinking or just want to have fun in long hours.
