i got this thing in a trade.

i swapped out the spring, nozzle and cylinder head. I noticed that the nozzle was a little bit shorter that the stock so i switch back. it was maybe a gain of 40 fps. i put an M130 in it and cut the spring down a little bit. It's a tad longer than the one that was stock. I am literally only getting 140 fps. I changed bucking and the problem isn't there.


Could cutting the spring too short have caused this? literally makes no sense for it to be doing that,,
