Detailed Review

The AK1 is essentially an all-metal cast receiver that's encased by a plastic/composite shell molded to closely resemble the iconic AK-47. While it looks like an all-plastic gun sitting in the box, the moment you pick it up, you realize that you are holding something far more substantial. Coming in at a solid 8 pounds, the Crosman AK1 feels very realistic and durable.

There are some key features built into the stock like the four Picatinny rails that surround the forearm. The blowback cocking lever operates to cock the gun for that all-important first shot, and it cycles when fired adding to the realism. The 5 position stock allows shooters to adjust the pull to suit their frame and the open sights, while not adjustable for windage, lined up perfectly on target once adjusted properly for elevation.

The front faux muzzle brake and the floppy stock, when in the closed position, are among the most notable features that you might consider inauthentic. The non-functional AK parts molded into the plastics also detract from the overall aesthetics. But in general, it feels and looks pretty good.

The AK1 bb rifle is fed CO2 and BBs via a drop-free mag that holds two 12 gram CO2 cartridges, a seating tool, and up to 28 steel bbs. Given that the AK1 has the all-important "more fun" switch, you'll want to get extra mags so that you can allow the CO2 to recover in one while you are shooting from another.

Loading the magazine is very straightforward. The two CO2 cartridges drop in and the seating tool is used to pierce and seal them. Loading the BBs is accomplished by pulling down on the spring and locking it into place. This allows the BBs to be easily loaded via the loading port. Once full, carefully release the spring and you are all set.

The magazine loads easily into the bottom of the receiver and is held in place by a rear mag release. The fire selector is located on the right side of the receiver as you'll find on an AK-47 replica. The top position is safe. The middle position is full-auto and the bottom position is sem-auto.

Accuracy, Power, and Shot Count

Because the AK1 uses CO2, which freezes and drops pressure when expelled quickly, velocity and shot count will vary widely based on how you shoot it. If you single fire, you'll see the highest shot count, velocity, and accuracy. If you opt for full-auto, which is certainly more fun, the CO2 becomes unusable after about 2 magazines. So, a single-shot operation, with time spent between shots, will yield about 100+ usable shots. With rapid-fire or full auto, you'll see that drop to about 58 shots.

The same principle applies to velocity. New CO2 cartridges, tested at around 68 degrees, pushed BBs at 372 FPS with subsequent shots dropping fairly quickly to the low 300s. With rapid-fire or full auto, you may see velocities dipping into the mid to high 200 FPS range. Ambient temperature will play a big role in how well the gun performs.

With years of experience shooting all forms of airguns, our expectations were relatively low when contemplating its potential accuracy. We're pleased to report that accuracy surpassed our expectations. The open sights, as mentioned above, were on target left to right. Once we adjusted the rear sight for elevation our first shot hit just a fraction left of dead center. So did the next shot, and the next shot. We were shooting from a standing position at about 20 feet from the target. We emptied the mag into the target and were extremely pleased with the results, especially from a smooth-bore BB rifle.

We spent the rest of the afternoon shooting in both semi-auto and full-auto modes and the AK1 continued to impress us. It's very easy to dump the mag while in "more fun" mode into a relatively consistent group with few, if any, flyers nearly cutting soda cans in two. Over hundreds of rounds, maybe thousands of rounds (we lost count of the co2 cartridges and bbs we shot) the AK1 performed without a single hiccup.

Summing Up

With the AK1, Crosman has delivered an impressive select-fire CO2 rifle. There are many AR15 variants, Crosman's own DPMS is a great example, but there aren't many AK variants. The AK1 fills that void nicely. It feels good to hold and shoot. It has a realistic weight and basic AK switchology. More importantly, it has a shot count and accuracy that matches its build quality. The ability to purchase readily available CO2 and inexpensive .177 BBs, along with extra magazines, make the Crosman AK1 an all-day shooter for very little money.
