The LWRC REPR MKII Upper (LWRC part no. REPRMKIIU65B22) is a complete AR-10-pattern upper receiver assembly chambered in 6.5 Creedmoor, built around a 22-inch heavy-contour barrel and finished in black. It uses LWRC’s short-stroke gas piston operating system instead of a direct-impingement gas tube, which keeps the action running cleaner and cooler over long strings of fire, and pairs it with a rear-mounted, non-reciprocating charging handle for faster manipulation without moving anything near the shooter’s face. Built for long-range precision and hunting applications, this upper drops onto a compatible AR-10-pattern lower to deliver 6.5 Creedmoor’s flat trajectory and retained energy at distance. It’s a direct way to add a purpose-built long-range upper to an existing AR-10 platform rifle.
