A Full-Length Upper Chambered for the Hard-Hitting 300 Blackout Cartridge
If the 300 Blackout round was designed for use in an 8-inch barrel, imagine the kind of increased power you could get from a fired round by chambering it in a barrel twice as long? You're used to 16-inch carbines, but this Stag Arms Stag-15 Blackout upper receiver is outfitted with a big-bore, .30-caliber barrel that gives you a hard-hitting thumper of a platform in a size you know how to manage well.
Each Stag Arms Stag-15 300 Blackout upper receiver features a QPQ-nitride-finished 16-inch barrel complete with a 1:7-inch twist rate. The muzzle end is crowned with a classic birdcage-style flash hider, and the entire package is finished off with an ergonomic, attractive Stag Slimline handguard complete with M-LOK attachment slots.
