Product Information:
great upgrade kit for the cost. i used it in my utg l96 and it works great.. the piston is pretty much the same as the stock piston but its metal so thats either good or bad for you. also the spring is much stiffer than the stock spring. but its still not to hard to cock. and the spring guide is pretty good. not sure if the ball bearing actually help but i have them in there anyways. also the spring guide had a hole through the center so you can still use the cocking indicator

high quality piston. provides a good seal. ( i put the old oring on top of the piston just to add a little extra)
spring is stiffer than stock spring
spring guild is fine.

wont work with the AGM l96. the spring will..but the piston and spring guide wont. no idea why.
