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.

I bought two sets to see if they were any good. I was very happy with the quality and ended up buying 5 more sets.
Once I figured out I had to put it in at an Angle I'm very happy, instead of paying 170 for the bcm quadrail to go with my bcm4 I'm definitely ok to have this on can't tell the difference
This is a perfect fit for your AR with a front sight post. The rails slip in perfectly and there are no sharp edges at all.
Quad rail arrived quickly and was made of quality material.
Thank you for the excellent service and fast shipping!
Once I realized that you have to install it on an angle,
These rails fit perfect and are rock solid on the Colt 6920.
Another one of the many purchases from AU perfect and fast especially during these times
