Polymer80 has introduced the next greatest 80% lower for the AR-10/DPMS .308 market! The Warrhogg .308 AR-10 Polymer 80% lower, now available in gray, takes on the .308 AR-15 platform with a featherweight design that also brings that promise of ruggedness, compatibility with all current 80% jig and DPMS .308 components, and a simpler machining process for beginners!

Tested, reinforced, and proven at the range

Polymer80 has repeatedly tested, redesigned, and tested again their Warrhogg .308 80% lower to ensure safety and reliability. The Warrhogg is built from the same polymer that all other current-production polymer firearms are made from – but they didn’t stop there.

To ensure its ready for abuse, Polymer80 reinforced the Warrhogg 80% lower with a solid core design. A reinforced buffer tube ring, ribbing across the top, a no-thread pistol grip, and a stiffened mag well all ensure the Warrhogg is capable of handling thousands .308 and NATO 7.62, all while weighing less than half a pound.
