Do we have any owners/users/operators (operating operationally
) of the BRN-4 uppers now that they’ve been available for a while?
I recall some anecdotal posts about machine marks being fairly prevalent which is annoying for the price point. Brownells even notes that now on the product page. Beyond that I haven’t seen much else.
I’ve got plenty of piston guns but I’ve stayed out of the piston AR realm. (Though I’ve gotten close with the T91 uppers…) Something about these specifically is intriguing, maybe the HK forbidden-fruit aspect? The RAL-8000 accessories? The various Euro militaries adopting them? Dunno! Part of me wants to try to build an M27 clone, another part of me thinks a random mashup 416 could be fun.
I’d love to see some feedback like how they are working, do they behave with suppressors, did Brownells/PWS hit the performance mark even if they are cosmetically dogs at times?
