    AU 7" Drop-In AR15/M4 Carbine Length Quad Rail

    Description:

    The AU 7" Drop-In Carbine Length Quad Rail is a high quality 2-piece picatinny forend replacement for all mil-spec AR15/M4 carbine length plastic hand guards. They mount exactly like the factory hand guards but dissipate heat much more efficiently. Rails are located at the 12, 3, 6 and 9 o'clock positions, there are also 5 quick detach anti-rotate swivel ports located throughout for ideal sling attachment. The AU design ensures a secure fit with no movement on the weapon while providing a solid mounting platform for accessories. The precision machined rails enable consistent repeat of zero for any accuracy dependent devices such as optics or lasers.

      Very Nice!

      I was shocked when I put this on my ride. Very well made and a nice finish. I was expecting a budget product that was going to temporarily replace some cheesy Magpul gear and it ended up becoming a permanent fix. I might put this on another rifle too. These are a smoking deal people.

      For 20 bucks?? Are you kidding me? Fantastic deal. I bought 5, installed on 4 weps, and have one in reserve. Good quality, QD holes are to spec, and they fit perfectly on my , Colts, and Bushmasters. Very happy.
