LWRC IC-MK II R5 CK 14.7" Barrel .223 Rem/5.56 NATO Rifle

The LWRC IC-MK II R5 CK delivers precision engineering with its 14.7-inch cold hammer-forged barrel and monolithic upper receiver design. This rifle combines LWRC's proven piston-driven system with enhanced modularity for professional and civilian applications.

What Makes This Different

The IC-MK II features LWRC's proprietary short-stroke gas piston system that runs significantly cooler and cleaner than direct impingement alternatives. The monolithic upper receiver eliminates the barrel nut entirely, creating a stronger platform with improved accuracy potential. Cold hammer-forged barrels undergo a 4-hour process that creates superior bore consistency and extends service life beyond 20,000 rounds.

Key Features

• Short-stroke gas piston system reduces fouling and heat transfer to bolt carrier group
• Monolithic upper receiver with integral Picatinny rail system
• Cold hammer-forged, chrome-lined 14.7-inch barrel with 1:7 twist rate
• Ambidextrous lower receiver with enhanced magazine and bolt releases
• LWRC's advanced trigger guard and winter trigger guard compatibility
• Spiral fluted bolt carrier reduces weight while maintaining strength
• Fully adjustable gas block for suppressed and unsuppressed use

Field performance demonstrates consistent sub-MOA accuracy with quality ammunition, while the piston system maintains reliability through extended firing schedules without cleaning. The 14.7-inch barrel length provides excellent ballistic performance for patrol, competition, and defensive applications while remaining maneuverable in confined spaces. Weather testing confirms function in temperatures from -40°F to 140°F with minimal point-of-impact shift.
