"Tripled my GR16 CQW Rush's range and accuracy, fanatastic upgrade part for anyone looking for more range.

"I am disappointed with this so called "upgrade". I put mine in the CA M15 and it needed the back end of the bucking trimmed off with a knife to fit. That was no problem compared to getting the bucking on. I used tonnes of Silicon Oil but it was still hard to slide on. I tried 3 times unsuccessfully and the bucking ripped. Then I tried again with the other bucking and managed to get it on pretty good (except it still wouldn't go on all the way around). When I tried it the gun; accuracy had increased by 2x, but the range had decreased by 3x and I had the hop-up maxed! It was also double feeding now and then. I assume this is because part of the bucking lip had refused to stay in place infront of the barrel. So then I had to disassemble and tried the old bucking with the MadBull nub, and that fixed the double feeding problem, but the range was still 3x as bad as stock!
