Upgrade your AR-15/M16 with the Ohhunt Free Float Quad Rail Handguard, designed to preserve barrel performance while expanding your accessory mounting options.
- Free float quad rail installs on standard mid-length AR-15 rifles, attaches directly to the receiver without touching the barrel, and lets you mount bipods, grips, or sights for a modular setup.
- Made from 6061 aluminum with a matte black finish, it's offered in 4", 7", 10", 12", and 15" lengths; weights range from 217 g to 610 g, with a 1.7" internal diameter and a 2.43" width/height.
- Installation notes: the aluminum barrel nut is lighter than steel but can be damaged during installation; use no more than 35 pounds of torque; requires additional gunsmithing tools and expertise; not compatible with Bushmaster Carbon 15 rifles bearing serial E18000+ unless using the Bushmaster barrel nut.
- Includes: free float quad rail handguard, aluminum barrel nut, castle nut, anti-rotation set screw, and Allen wrench; designed for AR-15/M16 platforms and supports precise, repeatable accessory mounting.
