I run H buffers in my 16" BCM Middies and they work fine.
H buffer in BCM 14.5" mid ran fine with everything; switched to A5H2 and had zero failures in 800rds. Going to a5h3 and will test that out and report back on Monday or Tuesday...have PMC 223, federal 223, independence 556 as well as Hornady 75gr TAP in 223 and 556 to try out.

Spikes Tactical ST-T2.
Successfully run H, H2, and H3 buffers with my 16" BCM, and SIONICS uppers. Fodder used were xm193, xm855, other m193 spec, Fed ar223, PMC bronze 55gr, and Herters 55gr - all good to go.
Ran a Spike's Tactical ST-2 for 200 rounds or so, no issues.
Now running an H buffer because it came with new stock assembly and I'll see how it goes.
BCM 14.5 pinned Mid length
Currently building an upper with a rainier 14.5 chf middie(link to barrel at bottom) wondering what a good starting buffer/ spring setup would be. Upper will be ran with an aac 762sdn6 about 50% of the time.
