The Solo 300 is something new in the AR-15 world; a manually operated, straight-pull 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 AR-15 lower, with or without buffer tube. And because it's based 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 350 Legend on the market.
