||I'm VERY VERY VERY VERY VERY glad that I bought this. I have a G&P MOE M4 and have had problems ever since I got it. I spent money replacing just about every internal (gearbox, everything in the gearbox, bucking, spacer, and inner barrel), but the problem still didn't resolve. The last thing to get was a hop up, so I got this one, and now I have a lean, mean, foliage green killing machine!
FIXED MY M4's PROBLEM!!! THANK GLOB!!!
Really easy to build. I've never built an M4 hop up before, and I didn't even have to look up how to do it.
O-rings make for a good air seal
Comes with everything you need to assemble the chamber (doesn't include bucking or spacer/nub)
The gears don't move very easily, so once it's set, it's set for EVER (probably not).
It would look cooler if it wasn't so red, but I don't care that much
Never wants to play Xbox with me. It's always, "I'm too busy reading, why don't you go do your AP homework?"
Sometimes doesn't pay its half of the rent.
