    Every cycling, extraction or ejection problem that gets posted about here and that same guy blames it on the extractor spring...

    No matter what - 'You need a new Colt extractor spring'.

    My assigned weapon has a SOCOM barrel, and an H2 buffer. Consequently my home brew SOCOM build runs an H2 buffer. Both run like a top.

    You don't "need" an H2 buffer, your upper should work fine with an H1. Colt 14.5s are not overgassed unless you run a suppressor.

    As has been said here, I run H2s in carbine gas ARs but half the reason is for a little more reciprocating mass to strip and chamber rounds.

After doing some reading, I’m understanding that the rifle is over gassed? Further reading I understand Colt shipped H buffers with the 6920, but shipped H2 buffers with the SOCOM barreled 6920’s. I’m trying to understand if both rifles are semi-automatic, is there a reason why Colt would use an H buffer for the 6920 and an H2 buffer for the SOCOM 6920? How would the thicker barrel of the SOCOM necessitate a heavier buffer? Or am I interpreting this wrong? I’m trying to figure out if I should get an H2 buffer or not, due to the perceived over gassing.
    I'm pretty sure Chris Bartocci of Small Arms Solutions mentioned Colt uses the H2 buffer in the M4A1 because they have full auto capability and it help with bolt bounce.

    This part I don’t understand.

    How if two barrels are of equal length ie 14.5 in, how can the SOCOM barrel generate more inertia? I thought the SOCOM barrel came about due to barrels bursting under full auto fire?

    Increased mass of the heavy barrel causes more bolt bounce.

    While this is true, the H2 buffer was developed with the lightweight barrel in 1999.

    M4 or pencil? I knew it’s been around for awhile, but thought it was first put to widespread use with the M4A1.
