Questions about some parts (Muzzle, buffer)

[lead chucker]

I think using a brake or flash hider is personal preference. I put a JP SCS tungsten in my SBR for my grendel and a 8" blkout and can't be happier with it. I also use one in my 16" blkout with a carbine gas system with sub's. I was worried it would be to heavy for sub's to cycle but it cycles great with sub's. If you want one I would go with the tungsten.
