Two questions, first one I'm pretty sure I've asked before, but better to be safe.
So, can you guys pin/weld a muzzle device onto an already assembled upper? It has a 13" rail w/14.5" barrel, so not a lot of barrel sticking out if you need to clamp down on it to do the drilling. I can disassemble if need be, but obviously it would be easier (for me) not to.
Secondly, the muzzle device is a mount for a Silencerco Saker but is manufactured by BE Meyers (specifically, it's a BE Meyers 249S). I see two different prices between Silencerco and BE Meyers muzzles devices under "shop services," hence the question. I would assume it would fall under Silencerco since it essentially has the same rear half as any other Silencerco Saker mount, but once again, better to check before sending it off to you.
