Product Overview
Product Description
The MK18 RIII builds on the proven MK18 platform with a fully ambidextrous lower receiver, letting left- and right-handed shooters run the bolt catch, safety selector, and magazine release without breaking their firing grip. The ambidextrous GRIP-N-RIP charging handle extends that same accessibility to charging the weapon. A 9.5 inch RIS III rail, inspired by the two-piece RIS II handguard developed for SOCOM, adds M-LOK attachment points while keeping weight down. The rail surrounds a free-floating, cold hammer forged 10.3 inch government profile barrel — the same barrel length associated with the MK18 upper and its reputation in close-quarters applications. Rounding out the build are an ergonomic buttstock and pistol grip.
