CMMG builds their free-float KeyMod handguards to work with standard mil-spec AR-15 upper receivers. The barrel nut and mounting hardware ship with the handguard for a complete installation. In addition, the free-float design ensures no contact between the handguard and the barrel, improving accuracy potential and heat management during sustained fire. Furthermore, the KeyMod slots run along the sides and bottom of the handguard, giving you compatibility with KeyMod lights, lasers, grips, and rail sections. Also, the lightweight aluminum construction keeps your build weight down without sacrificing structural rigidity. When you need a free-float handguard that installs cleanly on a standard upper and gives you full KeyMod accessory compatibility, this CMMG handguard is a dependable choice for AR-15 builds.
A 7 inch handguard is one of the most compact free-float options available for AR-15 pistol and short-barrel builds. It keeps the overall package tight while still giving you M-LOK and KeyMod mounting positions for a light or a vertical grip. When you are building a compact AR-15 pistol or SBR and want a clean free-float setup without excess rail length, a 7 inch handguard from CMMG is a practical and streamlined choice.
