Built around LWRC’s MonoForge monolithic upper, the R.E.P.R. MKII SC Elite features a continuous, numbered Picatinny rail that runs from the receiver through the free-float aluminum handguard for straightforward optics and accessory mounting.
The 22-inch Proof Research barrel uses a stainless-steel core wrapped in carbon fiber, reducing weight while improving heat dissipation. It is threaded 5/8-24 and capped with the LWRCI Ultra Brake, ready for a suppressor or other muzzle device.
A 20-position adjustable gas block lets shooters fine-tune the short-stroke piston system for ideal performance with or without a suppressor. The nickel-boron-coated bolt carrier group further enhances reliability and ease of cleaning.
Shooting comfort and control are elevated by the Geissele SSA-E two-stage trigger, fully ambidextrous magazine release and safety, and a non-reciprocating, folding side-charging handle. The adjustable LWRC stock and rubber over-mold pistol grip round out the shooter-centric package.
