The Solo 300 is something new in the AR-15 world; a manually operated, straight-pull bolt action upper that requires no buffer tube. 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.

Whether you configure it as an SBR, braced pistol, or a true handgun, the Solo 300 upper gives you the lightest, most compact 300 Blackout on the market.
