I got a new triarc 13.9 Compelte upper recently and just started building out the lower. I have an a5 buffer tube for it but need to order the buffer. I won’t be shooting suppressed, does anyone know what a5 buffer they recommended? I emailed them but they haven’t responded yet.

Most likely an A5H2 or equivalent, that's what I'd use.

Speaking for my Track 3.0, they suggest A5H1.
