Attach Picatinny Rail to Milspec Carbine Polymer Handguard

This rail panel is direct attach to any Mil-Spec A2 or M4 handguard to mount accessories such as foregrips and weapon lights. It can be used on the top or bottom of the handguard. The rail is manufactured to compensate for the angle of the handguards.
