Other than the obvious differences in cyclic rate,barrel,shroud, Bolt and such, what are the differences? I find quite a bit online about the M2, but cannot seem to find am M-3 manual. Are the tools got ntime and head space the same? It seems to have the smaller buffer spade grip than the few photos I have seen.
Have not shot this gun since my dad had it in 1992, and I want to do it right. Same congifuration as last time it was shot.

Thanks

M3 should have a larger buffer. aside from the lightened bolt, thinner barrel profile, barrel shroud, and later the KAC Flash hider, there aren't really any differences. timing tools are the same ect. My dad has had both at different times, and I had an TNW M2 back in 08. If there is any further differences I have yet to find them.
