Franklin Armory F17-L 20 Upper Kit 17Wsm 10rd AR Compatibility

The Franklin Armory F17-l 20 Upper Kit 17wsm 10rd Blk delivers a complete, install-ready upper receiver for your Milspec AR lower, harnessing the remarkable .17 Winchester Super Magnum in a piston-driven platform that offers cleaner, flatter shooting for pest control and varmint management. The F17-L R2 features the new Osprey Defense slim piston system that automatically adjusts for suppressed or unsuppressed use with no adjustments required, and it pairs perfectly with the 20 inch barrel threaded at -28 pitch, ready for compatible suppressors. A newly designed handguard (15 integrated barrier stop) is M-Lok compatible, while the upper is optic-ready to facilitate fast target acquisition. With a 1:9 twist, standard charging handle, and a F17 proprietary bolt carrier, this gas system uses OPS Piston and a low-profile gas block to optimize reliability and efficiency. The Aura muzzle device and Black finish complement the overall rugged, purpose-built design for pest control scenarios. Caliber is .17 WSM, and the package provides a streamlined solution to convert your AR platform into a precise, high-velocity option for controlled, humane pest management.
