LWRC International IC DI Standard AR-15 Rifle - .223 Rem/5.56 NATO, 16" Barrel - ICDIR5B16

The LWRC International IC DI Standard AR-15 is a purpose-built 5.56 NATO rifle engineered for shooters who demand reliability and precision without compromise. Built on LWRC's reputation for quality direct-impingement systems, this 16-inch rifle strikes the balance between portability and velocity that makes it equally at home on the range, in the field, or as a duty platform. The IC DI Standard arrives ready to shoot with a complete feature set that reflects LWRC's attention to detail in every component.

The heart of this rifle is LWRC's cold-hammer-forged, spiral-fluted barrel with 1:7 right-hand rifling and NiCorr treatment for corrosion resistance and longevity. Gas delivery is handled by a NiCorr-treated direct-impingement gas block and tube tuned for reliable cycling. The upper receiver is a one-piece monoforge design that pairs with a fully ambidextrous lower—mag release, bolt catch and release, and safety selector all operable from either side—making this rifle equally friendly to left- and right-handed shooters. The modular one-piece free-float rail eliminates the need for hand guards and gives you a clean, predictable platform for optics or accessories.

Controls throughout are intuitive and combat-proven. The ambidextrous charging handle, angled ergonomic fore grip with QD sling attachment, and Magpul MOE+ grip deliver natural positioning and confidence when you need it. The compact stock rides on a mil-spec 6-position buffer tube with H2 buffer and mil-spec spring—a proven setup that balances reliability and shootability. LWRC's advanced trigger guard complements the controls without getting in the way. All receiver and rail surfaces receive Type III hard-coat anodize for durability and corrosion resistance. The rifle ships with a Magpul PMAG and an A2 flash hider with 1/2 x 28 TPI muzzle threads, ready for suppressors or other muzzle devices. At 6.6 pounds and collapsible to 32 inches, this is a rifle built for people who actually use their AR-15s.
