"I have bought 2 of these and love them. I have one in my Elite Force CQB and one in my G&G Combat Machine. They both work very well. my E.F. gets about 445FPS and my G&G gets about 440FPS with 0.20g BB's. with 0.25g BB's I am just under 400FPS with both of them. Legal with the fields that I play at. I shot 0.28g BB's out of them which puts me at 375-380FPS with them.
Now I just have to but me a motor that what get hot and stop working during a game. Mine works ok as long as I just use single shot but, when you use full auto and it stops with the piston on the last tooth, it mine does not have enough torque to start back up from there. Have to take the gun apart and reset it every time.
"Just added this to my CYMA CM028U AK to bump it up a little for outdoors. Spring was a beast to put in compared to the stock spring. And I had to upgrade to the 9.6V battery as stated. The stock battery wouldn't even turn it over! Other wise I have been out a few times with it, full auto and semi without any other issues. Stock motor and all other stock parts + internals.
I don't think I would go any higher though without another motor. This seems to be a good size to get a bit more bang out of your gun without breaking everything.
"I bought the m125 spring and dropped it into my MK43 (stock except for teflon tape on the bucking and modified nub). After 5,000 bbs it was clocked at 2.1 joules - that's 475 FPS with .20s, 425 with .25s.
Careful because this thing does what it says and then some!
