(1 reviews) Write a Review

100% Risk Free, Lifetime Warranty

Equip your DPMS LR-308 compatible rifle with our 15 inch quad rail handguards! With four Picatinny rails, our quad rail allows for the mounting of standard Picatinny accessories such as bipods, front grips, optics, or tactical flashlights. The free float design attaches directly to the upper receiver without touching the barrel or impacting barrel harmonics, resulting in better accuracy.

Note that the aluminum barrel nut is significantly lighter than steel barrel nuts, however it may be subject to damage during installation. We recommend using no more than 35 pounds of torque during installation.

The barrel nut is built specifically for use with low profile DPMS LR-308 pattern or compatible upper receivers. This rail is not compatible with the DPMS GII rifle. To confirm whether this rail will fit on your rifle, please click here to refer to our AR-10/AR-308/LR-308 Handguard Compatibility Guide. Please note that installation of a free float handguard requires additional gunsmithing tools and expertise. For questions regarding fitment or installation, please refer to our AR-15 quad rail guides and installation guides.

      • Quad Rail Install very easy and looks great!

        Posted by David McDaniel on Mar 6th 2019

        I installed the quad Rail onto my DPMS LR308 in a matter of 25 minutes. The old barrel nut was hard to get off but the install of the free-float quad rail was extremely easy. Worth the money and make sure you get the end spacer kit for $10.00 as it makes the business end look neater. Wish I could upload photos.... 5 our of 5 stars.
