Does this appear to be a pinned FH to you? It is a 14.5 upper with what I think is a pinned FH, is that what this is in the pic? If not, I do have a registered SBR lower, so no issue there. Thanks.

Yep. Pinned/welded then smoothed out with a flap disc

I thought it was but wanted to verify it before I used it on a non-SBRd lower. Thanks.
