Had a kwa cqr mod 2 just sitting around that has seen a lot of action. Decided to upgrade it so I can have another field rifle for a back up or if any friend needed a rifle to use during a match.
Dropped one of these in and while giving me about 10 extra feet, the accuracy actually went down from my kwa stock barrel. Now to ASGI's defense my kwa stock brass barrel (6.05) has had a ton more rounds pass through. This causes the brass to actually become more smoother with more rounds.
My FPS is a consistent 389/390 with .25's every shot. While using my KWA stock barrel all the rounds will start to drop off in the exact same spot with very little to no flyers. As stated above, I've gained an extra 10ft but every 2nd to 3rd shot will be a horrible flyer.
I'm guessing it needs a lot more rounds through it to break it in and the accuracy will start to make itself more consistent.
3/5 For now for awesome customer service (I will never give my money to anyone else)
Horrible accuracy. Never know if it's going to fly true and straight (hopefully as more rounds pass through it will smooth itself out and become more sufficient)
