Review for the Cmya cm-028 AK47 airsoft replica

This is a partial review. This review will be update in a few weeks once we have completed our testing process and gotten the replica chronographed.

The 028 seems to be the first AEG in the cmyk series that was really favorably reviewed by most users as I started looking for entry level replicas that didn't suck. And they were all right... this AEG is pretty damn good for around 100 bucks!

First impressions: The airsoft replica comes in a pretty standard box (36 1/2” x 9 1/4” by 3 1/4” deep). The replica is laid into molded Styrofoam so it is fairly well protected in transit. The cardboard box cover is reasonably rugged, and the box can be used for transport until a more suitable case is acquired to transport the replica.

Opening the box, the replica looks quite good to the eye. The molded plastic stock and hand grips look a lot like real wood, and the grain in the molding is quite well done. There is a lot of metal on this replica as well. The upper receiver cover, the trigger and housing (which includes the magazine catch), the fire selector lever, the sights, the front gas tube and outer barrel are all metal.

The barrel machining is quite authentic, and the stamped steel upper receiver is also close the the real rifle this replica is modeled on. The cast aluminum bolt cover pulls back on a decent spring to reveal a slide type hop up adjuster and closes with a nice metallic “chunk” though not as forcefully at the actual weapon.

Of note with many AK replicas, the selector lever will scratch the face of the receiver as it is moved up and down. Also, the selector lever screw can be loose when you get the replica, ours was. It is a simple fix though; just pry off the plastic cap over the screw and tighten the screw a quarter turn or so with a philips head screwdriver, then snap the plastic cap back into place. This is such a minor issue it doesn't get any demerit points, as many lower end replicas have many more screws loose than this one did.

We took the replica out of the box, handled it a bit and noted that the sling that comes with the AEG is functional, but not overly great. It will work, and can be mounted in a number of ways, but you will likely want to replace this later on.

The battery comes uncharged, and here most sites warn not to follow the instructions on charging. If you charge the battery as long as the instructions tell you, the battery will likely overheat and possibly fail on this first charge. For the first charge, try 4 hours. Make sure you check the battery every half hour to see if the battery is getting hot. If it is, unplug it and let it cool before charging further. Most batteries will get warm as they charge, but hot is not good. As the battery gets warmer it charges faster, and it can get into a runaway charging cycle that can easily destroy the battery if it isn't allowed to cool.

Once our battery was charged, we loaded the included metal high capacity magazine with a couple good sized hand-fulls of .20 gram 6mm bbs and headed outside to play with our new AEG.

The magazine locked up cleanly with minimal wobble, and a few turns of the wheel on the mag brought bb's up to the mag well and ready to fire. For those who have not used a high capacity magazine, a wheel on the bottom of the magazine winds up an internal spring that feeds bbs up out of the magazine into the AEG's hop up chamber, so you do have to wind them from time to time.

I took aim on a large standing weed we often use as a target, which is located out about 90 to 100 feet using the built in iron sights. The bb passed within a half inch of the pencil thin plant stem, and the third one hit it. Accuracy is damn good for a totally stock AEG. At this distance, the hop up has not taken effect yet, so the bb's trajectory is still reasonably straight. At about 130 feet the back spin from the hop up started to take effect and the bb began to climb in flight. Opening the bolt cover on the side of the receiver, it was simple to move the slider to adjust the hop up so that the hop up backspin took effect later in the bb's flight.

With some slight elevation of the muzzle, we were able to almost reach the far edge of the field where the tree line starts. This is about 210 feet from our shooting position, so the maximum range on the AEG is pretty decent (roughly 180 feet). Accuracy at this range is not expected, but even on full auto, the bbs were all falling within a 2 foot wide by 2 foot tall window, so it is reasonable to expect to hit a person sized target out near the maximum range. Aiming is more difficult of course, and we had the sight set at the lowest position on the rail, so it wasn't set for long range. Note that on the lowest position, the replica seems to be close to on target at about 50 feet. We will do further accuracy testing with a bench later in the review.

Battery life for a stock el cheapo battery isn't bad at all. Many 600 round hi-cap mags later the motor was still turning over at about the same speed as when we started. We probably emptied 5 or 6 hi-caps just goofing around. The battery that comes with the gun is a NiCad, which is not as good as a NiHd battery, but it works for target shooting, light skirmishing and as a back up after you get a better battery later on. We had no trouble putting the battery in the flask of the stock (at the back end), though some online reviews from other people did indicate they did. The butt plate slides off and lifts away, revealing an ample battery compartment. A larger battery with more cells may not fit however, unless you are willing to disassemble the stock and remove a plastic rib inside the stock. Which voids any warranty. The battery fits fairly tight, but if you shake the gun hard, you can get it to rattle a little. A few turns of tape may fix this problem, but its not really needed. If you are moving that hard on the field, your body and other equipment will be making as much or more noise as that moving battery.

More soon! The snow is finally deep enough to get out and really run this replica through it's paces!
