LWRC ICMKII 5.56 NATO 16.1" - AR-15 Rifle

The LWRC ICMKII 5.56 NATO 16.1" is built for people who can't afford a malfunction. Engineered in 5.56 NATO to the same standards demanded by military and law enforcement users who stake their lives on their equipment.

Chambered in 5.56 NATO and running a short-stroke piston system, the LWRC ICMKII 5.56 NATO 16.1" is a semi-automatic AR-15 rifle engineered for consistent performance across a wide range of applications.

Built Beyond Mil-Spec: Mil-spec is the minimum acceptable standard; this 5.56 NATO AR-15 rifle exceeds it throughout. Components are selected for the tightest tolerances and best available materials, not the lowest cost.

Consistent Performance Under Pressure: Reliability when conditions are bad, ammunition is dirty, and the rifle is hot is what separates professional-grade platforms from recreational ones. This rifle delivers that consistency.

Match-Accurate Architecture: Cold hammer forged or precision button-rifled barrels, hand-fitted components, and proper headspace ensure accuracy that outlasts most optics mounted on it.

Professional Pedigree: The same manufacturing standards that supply military and law enforcement contracts go into every 5.56 NATO rifle that comes off this line — civilian availability, professional build quality.
