"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!

"Ok first off these are great springs. Matrix is by far the best springs on the market. I have used CA, Systema, Guarder, Promes, and a few more. Whats makes these springs great is its an all around good spring. They dont rust, they lose very little fps after break in, Irregular pitch, easy install, AND THE BIGGEST THING IS THE PRICE!!!! This thing is 10 bucks and about 13 shipped. Others listed above are the same price but most are 8-10 dollars more for a weaker spring. I have had a systema M120 spring just break in have and ruined piston.

Those who are saying this spring ruined their motor or blew their fuse have weak guns and or they were too cheap to put in a better motor which is generally what you should do with guns that have stock motors in the G&G, JG, ECHO1, DBOYS, even some G&Ps I have seen need a motor replacement when you get this spring. And for this to shoot almost dmr speed yes it easily fry a cheap crappy motor.
