The Phoenix G150 is Battle-Ready

While some say a polymer AR-15 lower is not robust enough, the community has proven the Phoenix G150 is just as capable as any aluminum 80% lower. Polymer80 repeatedly tested this lower in development, reinforcing its original construction by 15%. Metal hardware fittings and a reinforced, mil-spec buffer tube housing ensure the Phoenix G150 will cycle thousands of rounds without failure.

The Phoenix G150 is the Easiest-to-machine 80% lower!

The Phoenix G150 is an affordable 80% lower-and-jig combo you can find, making it perfect for practice or a first-time build. Pair the Phoenix G150 with any lower parts kits, a buffer system, and an upper, and hit the range in the same day!
