Has anyone done this upgrade to their M4's? If so could you advice me on any problematic issues that arise when disassembling the weapon and assembling it back together after installing the new parts. Thanks.
eh, im probably going 2 end up doing that 2 my m4....more reliablility with less power. go for it i say.
more reliablility with less power
I would advise you to do bushings along with that spring.
hehe i think addrian was talking that power difference based off his m120, but ya in my opinion M100s are all you need, no m120... dont gota push everything to the limit.... my ak with a m100 gets nice range, the G36c with a m100 got sick range too.
