LWRCI IC-MKII 5.56 NATO 16.1" Rifle

The LWRCI IC-MKII: Purpose-Built Performance

The IC-MKII represents LWRCI's commitment to delivering a rifle that performs reliably under the most demanding conditions. This is not a rifle designed by committee—it's engineered by shooters who understand what matters when it counts.

Operating System

At the heart of the IC-MKII lies LWRCI's proprietary short-stroke gas piston system. Unlike direct impingement designs, the piston operates independently of the bolt carrier group, keeping combustion gases away from internal components. This design delivers:

• Reduced fouling and easier maintenance
• Cooler operation under sustained fire
• Unmatched reliability in extreme conditions
• Consistent performance regardless of ammunition type

Construction and Features

Every component reflects serious engineering:

• Monoforge upper receiver: One-piece construction for superior strength and durability
• Cold hammer-forged spiral fluted barrel: Reduces weight while maintaining rigidity; the spiral fluting aids in heat dissipation
• Nickel boron coated bolt carrier: Reduces friction and wear for extended service life
• Ambidextrous controls: Bolt catch, bolt release, magazine release, and safety selector work equally well for left and right-handed shooters
• Ambidextrous charging handle: Positioned for intuitive operation from either shoulder
• LWRCI Skirmish BUIS: Backup iron sights that don't compromise your optics mounting
• Compact stock and pistol grip: Optimized ergonomics for modern shooting techniques

What's Included

The IC-MKII ships with a 30-round Magpul 5.56 PMAG—a magazine trusted by professionals and serious shooters alike.

The Bottom Line

This is a rifle built for those who refuse compromise. Whether you're training, competing, or preparing for the unexpected, the IC-MKII delivers the reliability and performance you need.
