The KJW MK-II is a powerful double action non-blowback Co2 powered airsoft pistol that looks and feels just like its .22LR counterpart. The gun is very comfortable to hold and fits your hand very well. The raised target sights with fiber optic front give an excellent sight picture during the day time.Thanks to the non-blowback mechanism, on a fresh Co2 canister, this pistol can shoot over 400+ fps giving you that extra power and reach. The other benefit to a non-blowback system is the gun will be much more gas efficient and will require less gas to operate.

"I would personally say that i love this pistol out of the box. It shoots well and i didn't need to adjust the hopup at all out of the box (don't know if that is the case for everyone). The gun itself is nice, but the one thing i notice while just messing with it a bit (firing it at different angles) after you aim it 45 degrees downwards, it doesn't fire at all, and every once in a while you do hear the click of it firing. I do not know what is causing this. But i thought i would let other people know of this.

"I'm going to be honest, I purchased this gun not expecting it to be worth much, but I am happy to say it over exceeded my expectations!!! The MK2 is about the length of a WE m92f and roughly the same width as a 1911. Full metal upper reciever and a polymer lower yet it still has a satisfying weight to it. As far as aftermarket parts, well there is none, but some ruger 22/45 pistol grips can be modified to fit. The fiber optic front sight is very nice but the block rear sight is kind of a drawback, I wish the MK2 had the MK1 rear sight. Anyways it is a very hard hitting pistol and great for outdoor, I was able to hit a man sized target from 120+ feet after I broke in the hopup.

Pros: affordable CO2 pistol
Very rugged construction
Fiber optic front sight
Excellent range and fps

Cons: trigger pull is pretty long and heavy, but it's a non blowback pistol
Rear sight kinda sucks, wish it had the MK1 rear sight
No aftermarket upgrades

Overall a great pistol for anyone

"Great pistol with extremely high power. At 400 FPS, I find it best with 0.30g bb. A co2 cartridge ($1) will last about 2~4 magazines which is pretty average for an Airsoft pistol especially at such high power.
