Franklin Armory F17-L Piston Rifle .17 WSM

Franklin Armory F17-L: The Future of Rimfire Pest Control

Franklin Armory has engineered the world's first piston-driven rimfire platform, and it's chambered in the potent .17 Winchester Super Magnum. This is a rifle built for shooters who demand cleaner, flatter performance across a wide range of hunting and pest control applications.

Key Features

Osprey Defense Piston System The proprietary R2 piston system automatically adjusts for suppressed or unsuppressed fire—no manual adjustments required. This means you get optimal performance whether you're running a suppressor or shooting open.

Precision Barrel The 20-inch barrel is threaded at 1/2"-28 TPI, the industry standard for rimfire suppressors. Combined with the auto-adjusting piston, this setup delivers exceptional accuracy and minimal recoil impulse.
