are all commercial m4s overgassed? and what are the signs of m4 being overgassed? all my friends run h or h2 on there m4s...what are the benefits?

kiki
So all your friends have full auto M4's? What unit they in.:rolleyes:
Your freinds are shooting AR15's not M4's! Run a Carbine buffer and spring and you'll be fine.:D
H or H2 buffer. The former is standard in the M4, the latter in the M4A1.
Ok, yes there m4 clones/carbine/semi wanna be...lol......
I'd say unless its race gun, run the heaviest buffer that your gun will reliably cycle. It'll help smooth out that recoil impulse....The A5 is going to be my next expense, heard nothing but good things.
This might help too http://www.ewp.rpi.edu/hartford/~ern...inalReport.pdf
That was a very comprehensive article. Not to start a piston vs di war but what suprised me was this:
Loads that are larger than a factor of ten worry me. So maybe there is some truth to those who say the external piston is harder on components.Quote:
Also, the offset loading of the bolt carrier causes higher friction loads between
the carrier and the inside of the upper receiver. The larger internal loads can cause
premature wear and failure of components over time. Even in the larger rifle length
external piston gas systems the predicted loads are larger by a factor of ten
Gas port size is the single most important determining factor when figuring out if your gun is over gassed.
