The LWRC IC-M5 MK II delivers advanced piston-driven reliability in a precision-engineered platform chambered in .223 Rem/5.56 NATO. This 16.1-inch barrel configuration provides optimal velocity and accuracy while maintaining compact maneuverability for tactical applications and sporting use.
What Makes This Different
LWRC's short-stroke piston system eliminates the fouling and heat transfer common in direct impingement designs. The monolithic upper receiver integrates a full-length rail system without the weak points of separate handguards. Cold hammer-forged barrels undergo stress relief and cryogenic treatment for consistent accuracy across temperature extremes. This design approach reduces maintenance intervals while improving reliability in adverse conditions.
Key Features
- Short-stroke piston operating system with self-regulating gas block
- Monolithic upper receiver with continuous Picatinny rail from receiver to muzzle
- 16.1-inch cold hammer-forged barrel with 1:7 twist rate
- Ambidextrous controls including safety selector and magazine release
- LWRC enhanced fire control group with 4.5-6 lb trigger pull
- Fully adjustable gas system for suppressed and unsuppressed use
- Compatible with standard AR-15 magazines and accessories
Field testing demonstrates sub-MOA accuracy potential with match ammunition, while the piston system maintains consistent cycling through 10,000+ round counts without cleaning. The rifle functions reliably in temperatures from -40°F to 140°F and continues operating after full submersion in water or sand. Competition shooters appreciate the consistent trigger break and reduced bolt carrier group mass for faster follow-up shots.
