Never built an AR before as im more of a combloc lover but the prices just scream "buy a reciever!!" so I said what the heck lets do it. Now, Id like all the experts here to help design the thing. Im looking to do a 300 Blk suppressed only (so subs) pistol/sbr build. Plan on going with the silent capture spring/buffer but unsure of barrel length and uppers selections and if a specific bolt carrier group is best? Overall id just wanna hear your "dream" component builds for the quietest setup
