I just finished, used some parts from previous builds for the lower, but the upper is all new.
It is Sun Devil Upper and Lower with RRA 2-Stage Trigger and A2 stock
The barrel is BHW 18" Mid-Length .264 LBC with Spriral Fluting forward the gas block and straight fluting behind the gas block. JP adjustable Gas Block. PRI "natural" Handguard with the riser. I topped it off with a Nikon Monarch sitting on a ADM mount. Also have a .308 Battlecomp, Phase 5 Trigger-guard, Phase 5 EBRv2 and GG&G Bi-Pod.
