Suppressor finally came in, and I was able to shoot it unsuppressed and suppressed for comparison. Unsuppressed, it shoots exceptionally smooth, if not obnoxiously loud due to the muzzle brake and ejects 55gr Wold Gold empties at 4:30ish. Wearing a SF 556 SOCOM RC, it ejects the empties at 2:30-3:00 and still feels smooth. I hope to get a few hundred more rounds through by June, but I'm pretty happy with the minimal functional impact from unsuppressed to suppressed.

Clint, not sure if you have already covered this somewhere, but what buffers do you recommend with the lightweight 16” midlength+ barrel. I’m about to complete two lowers for it, one carbine, one A5. Carbine lower has a sprinco blue. A5 lower will use a standard spring. Muzzle device is a 1815 flash hider, and I have a full mass bcg. Ammo it MUST function with is Fusion MSR. I also shoot a lot of proper 556 ammo. Edit: this rifle will never wear a suppressor. I have shorter guns for that.
Btw, my midweight 14” barrel continues to function reliably with 5.56 ammo such as M855 using H1, H2, and rifle buffers. Runs great and recoils like a .22 Hornet. I live in a warm place, so I’m not sure if it proves anything. But I’m a very happy customer. I’ve not cleaned anything in that rifle yet. Approximately 1,000 rnds.

I am sure Clint will step in, but I have used both A5H2 and Carbine H2 buffers with my light 16 Optimum barrel with standard (BCM) rifle and carbine action springs. The A5H2 was on a borrowed lower from my rifle and the new and dedicated lower has a carbine RE/H2.
My 16" Optimum has been flawless with a variety of factory 5.56 and .223 as well as modest handloads. Caveats are that I have not run it very dirty and I only shot a couple hundred rounds with the A5H2.

Well,
I finally took the plunge. I ordered the SPR barrel with a pinned gas block. I also ordered a Sons of Liberty NOX to pair with the barrel.
I'm very excited to get this build underway.
I'm checking interest in an 11.5" barrel with a taper at the end for a direct thread suppressor (Sig, Q as examples). It may be possible for BRT to make a run if there is enough interest. Post here or PM me if interested. Thank you.
