"LWRC is the premier CAGE defense contractor known for creating the most durable AR-15 builds. LWRC brings you a direct-impingement option with the LWRC IC DI AR-15 Rifle with M-LOK Handguard. The proprietary ambidextrous controls allow for seamless use between left- and right-handed shooters. The distinctive mono-forged upper and one-piece free-float M-LOK handguard flow seamlessly together for a singular, monolithic-style look and feel you won't get from any other firearm. LWRC's UCIW compact stock design offers collapsible functionality, a QD sling mount, and an excellent cheek weld. The LWRC cold-hammer-forged, spiral-fluted barrel features a Nicor-treated finish and brag-worthy accuracy. Land Warefare's ""keyless"" bolt design paired with their exhaustively-tested operating system guarantees a solid rifle to add to the collection. The lower receiver functions with LWRC's piston uppers, allowing you to mix the two or even upgrade to a piston-driven upper at a later date. LWRC offers the most rigorously tested and reliable AR-15 platforms on the market, paired with a degree of fit and finish unmatched in the industry.
