Need some "front end" to finish off that AR build of yours? How 'bout 13.5 inches of it? Put the finishing touches on your standard-sized AR-15 with this handguard. You get enough rail space on top to mount your backup sights or even optics. The M-Lok attachment system runs the 13.5 inches of the sides and bottom too for mounting tactical lights, lasers, grips, or whatever else you may need. And since it's free-floating, there aren't any connection points to the barrel itself, which means no interference with your AR's accuracy. Handguard comes with all necessary hardware for mounting; barrel nut, 2 hex nuts and bolts.


  • 13.5 inches in length
  • Made of billet aluminum
  • Picatinny/1913 raiiling on top
  • M-Lok railing on the sides and bottom
  • Extremely lightweight (Less than 1 lb.)
