LR-308 Quad Rail Handguard - 12 inch | Free Float | Black

Quad Rails

$ 74.95


Equip your DPMS LR-308 compatible rifle with one of our quad rail handguards! With four Picatinny rails, our quad rail allows for the mounting of standard Picatinny accessories such as bipods, front grips, optics, or tactical flashlights. The free float design attaches directly to the upper receiver without touching the barrel or impacting barrel harmonics, resulting in better accuracy.

Crafted from high quality 6061 aluminum, the quad rail is 12 inches in length, with an external diameter of 2.5 inches and an internal diameter of 2 inches, weighing only 1 pound.

The package includes an aluminum barrel nut, a castle nut, and an anti-rotation set screw.

The barrel nut is built specifically for use with low profile DPMS LR-308 pattern or compatible upper receivers.

Please note that DPMS LR-308 receivers come in two styles.  DPMS upper receivers manufactured before August 2009 have a high profile top rail, while upper receivers manufactured after August 2009 have a low profile top rail.  The top rail of our rails will mount square with low profile DPMS receivers, but not with high profile DPMS receivers.

This rail is not compatible with the DPMS GII rifle.
