The all new 16.5 inch Keymod Handguard is our longest ever! Built for longer barreled rifles, it extends further down the barrel, providing more rail space and more flexibility in accessory or hand placement. The free float design attaches directly to the receiver without coming into contact with the barrel or impacting barrel harmonics. The universal Keymod rail platform accepts all standard Keymod accessories. Available in black and flat dark earth.

Note that the aluminum barrel nut is significantly lighter than steel barrel nuts, however it may be subject to damage during installation. We recommend using no more than 35 pounds of torque during installation.

The barrel nut is built specifically for use with low profile DPMS LR-308 pattern or compatible upper receivers. This rail is not compatible with the DPMS GII rifle. To confirm whether this rail will fit on your rifle, please click here to refer to our AR-10/AR-308/LR-308 Handguard Compatibility GuidePlease note that installation of a free float handguard requires additional gunsmithing tools and expertise. For questions regarding fitment or installation, please refer to our AR-15 quad rail guides and installation guides.
