LWRC MKII Free-Float Quad Rail Handguard Featuring LWRC logo and TWO Quick Detach Sling Swivel Points • Brand New • AR-15 Quad Rail Handguard • Matte Black Finish • 6061 Aluminum Construction • Type III Mil-Spec Hardcoat Anodized with T-Marked Rails on all four sides • 7" in Length • Fits Any Standard Mil-Spec AR-15 Pattern Upper Receivers using standard barrel nut
The kit consists of three main pieces: 1) Lower section that contains the 3, 6, and 9 o'clock rails, 2) The rail clamp that attaches the system to the upper receiver, and 3)The removable top rail, which attaches to the lower section via hardened steel pins and 'J' shaped cuts that are found on the rail. These hooks and pins allow a 100% return to zero when removing and replacing the top rail. The top rail is held in place by pusher screws, which seat against special high-temp rubber o-rings.
The removable top rail allows the user easy access to the piston components on a piston operated gun or to the gas tube on a direct impingement gun. The top rail can be removed and replaced without tools other than the rim of a cartridge case. This rail kit fits any standard mil-spec upper receiver without any special mounting hardware.
