100% Risk Free, Lifetime Warranty
Equip your DPMS LR-308 compatible rifle with our 16.5 inch quad rail handguard for long barrel rifles! 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.
