350 Legend Complete Upper, 10"

The result is the lightest, most compact weapon possible on the AR-15 platform. The Solo 300 is compatible with any standard AR-15 lower, with or without buffer tube. And because it's built on an AR-15 upper receiver, it's compatible with all your favorite accessories, including free-float handguards and magazines of all sizes.
