Brothers n Sisters...

Once again i find myself wantin to build a 300 Blackout 16 inch barrel upper... Please school me as to your recommendations as to the best barrel, gas system, bolt, etc for this endeavour... The upper would have a simple free float handguard and tritium iron sights... 

Thanks a bunch in advance...

Are you planning on running subsonic loads at all? If so get a pistol length gas system and an adjustable gas block. If you are going to only run supersonic ammunition then get a barrele with a carbine length gas system. 

Subsonic loads will work with a carbine length gas system with a silencer but may not work without one. 

Beyond that standard BCG, buffer and spring should work.
