Platform Overview

The R20 RAHE REFERENCE is a battle-proven 5.56×45 NATO rifle built on LMT’s monolithic architecture. Its 14.3-inch barrel is pinned and welded to a legal 16-inch length—a common configuration for users who want a compact handling profile without sacrificing legal compliance. The integrated monolithic rail system and MLOK upper receiver combine to provide a rigid platform for optics and accessories with minimal torque or misalignment under sustained use.

Key Features and Field Advantages

At the heart of the design is the Gen 2 piston block, offering more consistent gas regulation for both suppressed and unsuppressed fire. The suppressor-ready flash hider speeds transition to suppressed operations while maintaining reliable dwell and cycling.

Ambidextrous Controls

The MARS-L lower receiver delivers fully ambidextrous controls: magazine release, bolt catch/release, and safety selector are all mirrored for left- and right-handed manipulation. These controls improve speed and safety in dynamic drills and when transitioning shoulders under stress.

5.56×45 NATO remains a versatile caliber—lightweight ammunition, controllable recoil, and flat trajectory make it suitable for close-quarters, patrol engagements, and precision-oriented work within its effective range.

Ergonomics and Accessories

Small, user-focused touches set this rifle apart: an enhanced trigger guard for gloved operation, a QD receiver end plate for modern sling interfaces, and the included BFG Vickers Sling in OD Green for fast transitions. The monolithic rail ensures any mounted accessories maintain zero and alignment throughout hard use.
