I'll be using a 16" DD 1/7 twist bbl with carbine length gas system and m4 cuts. Gas block will be a PRI low-pro with set screws. Forearm will be a JP midlength. Compensator will be from Nordic components. BCG and charging handle from WOA. Upper from CMMG with m4 cuts. Nothing special with the RRA lower to include the trigger.
pics inbound soon
