Upgrade your SIG 516 with this extended,?free-float M-LOK®?handguard. It installs directly over the factory barrel nut (nut not included) and provides a monolithic, continuous Picatinny top rail for seamless accessory mounting. Five anti-rotation QD sockets accept push-button sling swivels, while M-LOK slots along the sides and bottom give you ample real estate for lights, lasers, grips, or bipods. Machined from 6061 aluminum and hard-coat anodized, the handguard offers an ultra-solid lock-up yet weighs just 8.3?oz. It even extends past the factory front-sight tower—bayonet-lug and non-lug models alike—for maximum accessory space.
