LWRC Individual Carbine MKII Features The LWRC Individual Carbine MKII runs on LWRCI s proprietary short-stroke gas piston system a design that keeps combustion byproducts out of the action for dramatically improved reliability in sand mud and extreme heat compared to direct impingement rifles. The cold hammer forged spiral fluted barrel reduces weight without sacrificing strength while the 1:7 twist stabilizes a wide range of 5.56 / .223 Rem projectile weights for versatile ammunition selection. A nickel boron coated bolt carrier reduces friction and simplifies cleaning after extended range sessions. The Monoforge one-piece upper receiver ties the barrel and upper together for consistent point of impact and reduced flex under recoil. Ambidextrous controls including the bolt catch bolt release magazine release charging handle and safety selector let shooters operate the rifle with equal speed and confidence regardless of hand dominance. The LWRCI Skirmish back-up iron sights fold flush against the Picatinny top rail providing a reliable backup zero without interfering with an optic mounted for primary use. LWRC s compact stock and Ultra Combat grip give shooters a familiar ergonomic AR-pattern interface tuned for fast target transitions. A 30-round Magpul PMAG ships with the rifle rounding out a complete duty-ready package finished in Tungsten Gray Cerakote over the receiver.
