Things I liked: I completely love this gun! The look and feel is great, the trigger pull is better than you would think for a sliding trigger. Accuracy is a dime sized hole at 20', which amazed me for a barrel this short. Haven't put it over the chrono yet but I'd guess it at around 500 fps with 7gr RWS basics. I'll update when I've done the test. This has become a go to for me, can't speak highly enough about it!

Things I would have changed: The stock is pretty flexible, not a deal breaker but a little distracting. The molded in sights are mostly useless, but it's got a rail so I put a little reflex on it and it works great. I don't have to lay my head over so far for a sight picture with it so I would almost call a reflex a must. Probably the only somewhat significant issue is the CO2 magazine. It's hard to engage inside the grip, can pop back out under pressure or not engage fully. The only way you really know is that the gun won't fire if it's not engaged fully and it seems that you almost have to slap it into place.

What others should know: I get 3 magazines out of one powerlet, the accuracy is great, it's a blast to shoot! Buy one, you'll like it!

Things I liked: Great fit, weight, quality plastic and mold. Feels good in the hand and looks pretty legit for a replica.

Things I would have changed: A few minor things. Metal clip would be nice, its plastic. Maybe this is best from a design point because it works without issue but a metal clip would just feel and look more sturdy, Same goes for the stock, the metal hinge is great and solid but a stronger stock would have been a welcome addition. Maybe a possible upgrade down the road. I had no issue with the clip ejection button using my support hand. Seems designed to be used that way if you're right handed.

What others should know: Fires really well and smooth. The first two clips will really surprise you with how accurate this gun is with pellets, I used crosman destroyers. After that its spray and pray, accuracy really takes a hit as this gun uses quite a bit of c02. I got 72 rounds, 4 and a half clips, before the pellets were bouncing off of paper. Worth it for the first 32 shots though, very satisfying, fun to shoot, fits accessories really well and there are very few options for rifled barrel pellet shooters that are submachine gun replicas. Stand by my purchase, great gun.

  • JAMES from USA asked:

    How many rounds per co2 canister?

    • Gregory from Canada:

      Between 70-80 rounds per Co2 cartridge.

  • Michael from USA asked:

    Can anyone give me any input on how Crosman Destroyer .177 Cal, 7.9 Grains, Pointed, pellets might work with this gun? I'm trying to find a less expensive pellet than some of those recommended in the reviews.

    • Gregory from Canada:

      Read one of the first to reviews, the reviewer mentions using destroyers with his mp9.

  • brian from USA asked:

    Is there any internet user groups for the subject of this particular gamo airgun? What the community needs is a modifiable platform capable of selective fire. Something to replace the void left behind from the Drozd! Especially a selective fire that shoots pellets. The umarex is a failure as far as longevity or durabilty. Give us a hundred dollar full auto bb gun that lives past the novelty age and there will be a nice niche market!

    • Gregory from Canada:

      Look up the SMG-22 by "air-ordnance" is. .22 caliber seect fire with full auto pellet gun that works with HPA or Co2 and has a muzzle velocity of 600 fps with regular 5.5mm lead is awesome! American airgunner has a YouTube clip of Rossi shooting it.
