Includes: Free float quad rail handguard, aluminum barrel nut, castle nut, anti-rotation set screw, Allen wrench.Ĭompatibility: Not Compatible with Bushmaster Carbon 15 rifles serial number E18000+ unless Bushmaster barrel nut is used. We recommend using no more than 35 pounds of torque during installation. The aluminum barrel nut is significantly lighter than steel barrel nuts, however it may be subject to damage during installation. The free float handguard attaches directly to the receiver, without touching the barrel or impacting barrel harmonics, thus allowing for more precise shooting. Ohhunt 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.
