Franklin Armory F17-X 17 WSM 16" 20-Rd Complete Upper Kit - Black

The Franklin Armory F17-X is a 17 WSM complete upper receiver kit that drops onto any mil-spec AR-15 lower to build a piston-driven semi-auto rifle chambered in the flat-shooting .17 Winchester Super Magnum centerfire cartridge. Purpose-built for pest control, varmint hunting, and high-volume recreational shooting, the F17-X runs Franklin Armory's all-new Slimline Osprey Defense (OPS) gas piston system for dramatically cleaner operation, smoother cycling, and longer maintenance intervals than a traditional direct-impingement AR.

At the heart of this complete upper is a 16-inch lightweight threaded barrel cut with a 1/2x28 thread pitch for easy suppressor or muzzle-device fitment. A slim 15-inch M-Lok handguard wraps the barrel and carries an integrated hand/barrier stop for positive, repeatable hand placement. The entire upper is finished in durable Black, ships optic ready out of the box, and is supplied with one 20-round magazine so it is ready to run the moment it is mated to a compatible AR-15 lower.
