[ARCHIVED THREAD] - Need some input selecting my buffer.

Hi guys,

Finally putting together my SBR, but I'm still short a couple of parts. I have decided to go with a BCM 11.5 Carbine-Gas ELW Fluted barrel. And for the buffer I'm trying to decide between the heavy and regular sets of the JP silent captured spring system. (because I hate my wallet apparently)

Anyone have any experience with this barrel? Slightly overgassed? Do I need a heavier buffer? Will regular do fine?

All of my SBR's run 100%, some have adjustable gas blocks and some don't. But they all have h2 buffers. Do I need them? I have zero idea, but figured since I shoot suppressed often it wouldn't hurt to slow things down a little.

I have the non-fluted version and it runs perfect with an H buffer and regular carbine spring. It consistently throws brass at 4 o'clock. Edit: This is shooting unsuppressed.

Appreciate the responses from both of you! Looks like the heavy setup is what I'm going with. Thanks again

I highly recommend an adjustable gas block. I put one on all of my SBRs. Being able to use a standard spring and lighter buffer makes a good difference in recoil. Even the cheaper $50 Seekins has proven well if you do not plan on changing the gas much. If you are set on running a silent capture, I would recommend the regular spring with an adjustable gb.
