The SI Defense 2-Piece Customizable Mid Length Quad Rail free float handguard for the LR-308 is constructed of light weight billet aluminum, mil-spec anodized. The removable bottom and side rails allows the user to configure the handguard to suit their needs. The two-piece design clamps around the factory barrel nut, making the rail a true free floating design while eliminating the need to remove the existing barrel nut. Compatible with most aftermarket piston systems including Black Rifle Arms and Adams Arms.

The rail is designed for the High-Profile DPMS LR-308 (older style) and SI Defense upper recievers. It will work with the newer Low-Profile DPMS LR-308 upper receivers but the top rail on the handguard will be higher than the receiver rail.
