What buffer do you guys run in your suppressed SBR's? I have a LMT 10.5" with AAC M4-2K with a standard buffer. Just curious, I was looking at either a H2 or H3 but I am not sure which to go with. I just got the suppressor a couple months ago and when I would shoot it would stove pipe numerous times. Had some issues with some mags also, but since the gun has been dirty, it has been running pretty reliably. I use this rig for classes, matches, hunting, and home defense. I really wanna shoot a class with the suppressor but i dont want have issues all day tho.

I would order up both and test then out. Put 1 round in the mag and see if it will lock the bolt back, if it does you should be good to go.

I guess that would be a way to do it, every gun is different so I might try this or start out with a H2.

I run an H2 in my LMT 10.5" upper.  It functions perfectly with my Surefire Mini and Surefire 556-212.

You might want to look into the VLTOR A5 buffer system. I have had very good results with mine.

I have the 11.5 BCM barrel and SRT Typhoon w/standard buffer.  Rifle has been 100% for about 500 rounds with and w/o suppressor.

Try an H or the Spikes maybe. Just do process of elimination. I run the spikes in my 14.5 and works. For a suppressed 10.5 I would go H2 and try from there

If your budget allows, a JP silent spring is great. You van get extra spring sets and use them to tune the gun.

LMT says to run a H . I have a 10.5 and its good to go

I second the suggestion for the Vltor A5 system. I'm running an A5H3 buffer in my 11.5" BCM and it runs great suppressed and unsuppressed. With a standard RE and carbine spring I would probably go straight to the H3 if running suppressed the majority of the time. If the H3 proves too heavy you can always pop open both buffers and swap some weights around to make an H2.
