Precision Reflex (PRI)
PRI originally supplied the US Navy at NSWC Crane with the round forearm free floating handguard for the SPR rifle, which became the Mk12 Mod0. This is a recreation of the original rifle, with parts from PRI, Douglas Barrels and other mil-spec providers. Crane had originally produced the Mk12 upper receivers from commercial parts providers, like Precision Reflex. At the beginning of the War on Terror, when M4 parts were in short supply for regular ground forces, Crane was forced to take out of mothballs M16 A1 lower receivers to mate to the custom uppers that Crane built. Later versions of the Mk12 were found with lower receivers from Colt, Armalite, LMT and regular issue M4.
This Mark 12 Mod H for Holland is built with PRI's Retro Gen III, which is most representative of the 16" Hollard receiver groups.
This upper comes tested by PRI and ready to shoot 5.56mm NATO ammo. Charlie's recommends 77 grain Black Hills or Federal. The upper is equipped with a 16.5" Douglas 416 stainless steel barrel with a fitted bolt and commercial carrier, flat-top receiver, with a Gen3 PRI carbon fiber FDE handguard. AE Inc. brake and collar are standard, and profiled correctly to accept the Allen Engineering AEM-5 / Ops Inc. #12 suppressor. The system also comes with a Gen III Rifle length carbon fiber free float forearm in FDE finish and a full length Picatinny top rail. This upper comes with a FDE barrel.
This listing is for the 1:7 twist; however, we do also carry the PRI Mk12 Mod H FDE in a 1:8 twist (when available). Precision Reflex provides this reproduction with nice mix of period correct parts, PRI branded parts, and commercially available mil-spec parts to offer the history buff or shooting enthusiast with a good balance between authenticity, performance and price.
We try to keep these uppers in stock; however, demand often exceeds supply. When we are out of stock, and waiting for resupply from PRI, we offer our customers the option to put down a $250 deposit to reserve an upper from the next batch to arrive. If you place a deposit, we will invoice you for the remainder of the purchase price prior to shipping your upper.
