This Razorback II limited edition is factory-marked on the upper and carries distinctive artwork: a Razorback hog-head on the right magwell and the SIX8 circular logo on the left. The dedicated SIX8 lower is sized specifically for Magpul 6.8 PMAGs. The SIX8 upper features an enlarged ejection port tailored to the 6.8 cartridge. The receivers and handguard wear the brown/bronze finish, while components such as the stock, grip, buffer tube, sights, controls, barrel, and muzzle device are black/gray.
At its core is LWRCI's semi-automatic, short-stroke gas piston system with a two-position gas block for suppressed and unsuppressed use. The 16.1 inch cold hammer forged, NiCorr-treated heavy-profile barrel is spiral fluted and paired with a 1:10 twist for 6.8 SPC II. A multi-port muzzle brake/compensator is installed. The upper handguard half is removable via captive front screws for straightforward piston access and maintenance.
Controls are fully ambidextrous, including the bolt catch/release, magazine release, safety selector, and charging handle. The action uses the LWRCI Advanced Combat Bolt with a nickel boron–coated carrier. This configuration provides a robust operating group with enhanced surface treatment.
The LWRCI scalloped modular forend provides a full-length T-marked Picatinny top rail and a short 6 o'clock accessory rail. LWRCI Skirmish folding front and rear sights are included. Furniture consists of the LWRCI Compact adjustable stock and a Magpul MOE+ grip.
