For questions regarding fitment or installation, please refer to our AR-15 quad rail guides and installation guides. Please note that installation of a free float handguard requires additional gunsmithing tools and expertise. We recommend using no more than 35 pounds of torque during installation. Note that the aluminum barrel nut is significantly lighter than steel barrel nuts, however it may be subject to damage during installation.

Available in black, flat dark earth, and olive drab green. That being said, Troy, KAC and Midwest Industries make outstanding quad rails that are worth looking at. The free float handguard attaches directly to the receiver, without touching the barrel or impacting barrel harmonics, thus allowing for more precise shooting. Some people (like me) dig the aesthetics a quad rail had over a free float. Our 10 inch free float quad rail handguard installs on standard mid length AR-15 rifles and allows for the attachment of tactical accessories such as bipods, grips, or sights.
