The Noveske NSR KeyMod free-float handguard is the early KeyMod configuration and mates to a continuous 1913 Picatinny top rail that runs across the receiver and handguard, providing uninterrupted mounting space.

Length of pull is adjustable from 10.5 to 14 in, and the receiver extension is finished in black.
Construction is aluminum for both the receivers and the NSR handguard, finished in Flat Dark Earth/Tan. The upper includes a forward assist and an ejection-port dust cover. Chambered in 5.56mm NATO, the rifle is set up for a 30+1 capacity with the included magazine. Made in the USA.
