UTG Pro AR-15 Carbine Quad Rail Handguard Extended Top

This UTG Pro drop in quad rail fits carbine length AR-15s and adds an extended top rail that reaches back to the upper receiver, giving one continuous mounting surface for optics. The top and bottom halves fit the barrel nut and round front cap with no changes to the barrel.

Picatinny rails run on all four sides, and the rail measures 7.28 inches long. It is aluminum with a black anodized finish, and black rubber rail guards are included. It is built around a standard AR-15 gas tube; piston systems are not guaranteed to fit.
