LWRC's R.E.P.R. (Rapid Engagement Precision Rifle) is built for high performance for a multitude of roles. It features a short-stroke gas piston system which offers unparalleled reliability and easy maintenance. The cold hammer-forged, heavy-profile, spiral, fluted barrel is precisely torqued and has a black Nitride finish. The Monoforge upper receiver has integrated rail-base, while the fully-ambidextrous lower receiver controls include the bolt catch and release, magazine release, and safety selector. The lower receiver also features a Geissele SSA-E two-stage precision trigger and an oversized trigger guard. Its Magpul PRS adjustable stock has a Magpul MOE+ grip. The Di also has an ambidextrous charging handle, Skirmish sights, Ultra muzzle brake, Nickel-boron coated bolt carrier, and is Sub-MOA capable. This model has a 20" barrel and a detent which prohibits the magazine from ejecting when the upper is on the lower.
