Different Gas Lengths, Different Buffer Weights?

[Circle_10]

I tend to run regular H buffers paired with Sprinco Blue springs in most of my 11.5-16” carbine/midlength guns. I’ve tried H2s and the guns ran fine but for some reason I feel like I prefer the recoil impulse with an H vs the greater reciprocating mass of an H2. Given the relatively minor weight difference you wouldn’t think I’d even be able to tell but I *felt* like I could at least.
I did use an H2/Sprinco White spring during my rather short-lived experiment with a 20” upper on a carbine lower. Ran fine but I just ended up putting a fixed rifle buffer/stock back on it.

Throw an H2 in all of em and go in peace.

BCMs are gassed to run. They will literally run anything from a Car to an H6 and everything in between.

Our 16" carbine length gas systems run a H2 buffer with Sprinco blue springs. On my 14.5" SOCOM carbine, I use a BCM intermediate RE, a VLTOR A5H2 buffer and a Sprinco green spring. All run great.
