After two years of design, engineering, and testing, Polymer80 has brought a new, ultralight approach to the AR-15 80% lower! The Polymer 80 G150 80% AR-15 Lower with Jig System, is the world’s lightest DPMS-platform AR-15 lower.

Lightweight and maneuverability have always been a focus with the AR-15 platform. Weighing less than half a pound, the Polymer 80 G150 80% Lower promises to change the game – but is it strong enough? It's Made from weapons-grade polymer so it definitely is!

The G150 80% AR-15 Lower is constructed from the same reinforced material that all current-production, off-the-shelf polymer firearms are built from. Polymer80 took the time to test, re-develop, and test again, their polymer lowers until they achieved a unit capable of handling thousands of rounds without failure.

It features reinforcements based on real testing to guarantee reliability. Polymer80 beefed up the buffer tube ring, reinforced the receiver with a solid core, added ribbing across the entire top surface, and developed a no-thread pistol grip mount. Last, the mag well has been stiffened, all while retaining a featherweight profile.

A nice durable lower.


I have used several of these and these are great lowers. PLEASE!!!! Take your time and follow the instructions. Very strong, very durable over 500 rounds without a hitch. These make for a nice lite ar build. The one I built is right at four pounds. I love it.
