Machined aluminum free-float handguard offers many of the same features as the original SS Series handguards, with less weight and a slimmer profile. Only 1 1/2" wide, the Gen 2 models include a bipod stud and three bolt-on 2 1/2" rail sections, one with a built-in anti-rotation QD socket, that can be mounted anywhere. MIL-STD 1913 top rail offers T-marks for mounting points, and gives a neat, monolithic look with your flattop upper. Included barrel nut and barrel nut wrench enable easy mounting. Accepts Gen 2 SS-Series accessories only, no original SS accessories. 7" Carbine and 9" Mid-length models leave the gas block exposed. 10" Carbine, 12" and 15" Rifle models require low-profile gas blocks.
