FRANKLIN ARMORY 0010056ODG F17-L 17 WSM 20+1 20" BBL

The Franklin Armory F17-L (0010056ODG) is the world's first gas-piston semi-automatic rifle chambered in 17 Winchester Super Magnum rimfire, built on a matched set of Libertas billet 7075-T6 aluminum receivers in OD Green hardcoat anodize with a 20-inch precision bull barrel and a Black Bravo C stock. This is a purpose-built varmint and small game rifle for hunters, precision rimfire shooters, and sport shooters looking for a high-velocity semi-automatic platform in 17 WSM.

Special Features

• The F17-L is the first gas-piston AR-platform rifle chambered in 17 WSM, developed in partnership with Osprey Defense, operating a system adapted from centerfire AR design principles to cycle the high-pressure 17 WSM rimfire cartridge reliably in a semi-automatic action.
• Franklin Armory's Libertas billet upper and lower receivers are precision machined from 7075-T6 aluminum as a matched set, resulting in tighter tolerances than standard forged receivers and eliminating the upper-to-lower play common in mass-produced AR builds.
• The salt bath nitride treatment on the barrel extends bore life, hardens the surface, and improves corrosion resistance without adding dimensional thickness, keeping the bore geometry precise for long-term accuracy.
• The free-float handguard isolates the barrel from any pressure applied to the forend, protecting consistent point of impact whether the rifle is rested on a bipod, a bag, or held offhand.
• An integral bipod and tripod adapter is built directly into the handguard, giving you a mounting point for field rests without requiring a separate rail adapter.
• The factory custom tuned trigger provides a consistent, repeatable break suited for precision rimfire shooting at extended distances.
• The flared magazine well and ambidextrous QD sling mounts on the lower reflect a field-ready build designed for fast handling and rapid magazine changes in hunting and range environments.

Practical Benefits

• The 17 WSM cartridge launches a 20-grain bullet at approximately 3,000 fps from this 20-inch precision barrel, giving you a flat-shooting, high-velocity rimfire capable of taking varmints and small game at ranges well beyond what standard 22 LR or 17 HMR platforms can cover.
• The gas-piston action cycles the 17 WSM reliably and keeps carbon fouling farther from the bolt carrier group compared to direct impingement designs, which reduces cleaning frequency in the field.
• The optic-ready Picatinny rail on the OD Green receiver accepts any standard scope or red dot, letting you build your sighting system around your specific hunting or competition requirements.
• The M-LOK handguard gives you a clean, lightweight forend with accessory mounting positions for lights, barricade stops, and additional rail sections where you need them.
• At just over 9 pounds with a 20-inch bull barrel, this rifle is built for deliberate, precision-oriented shooting from a rest or bipod rather than fast-moving field carry, making it ideal for a dedicated varmint setup.
• Your investment in the F17-L gives you a rimfire platform with the ergonomics and modularity of an AR-pattern rifle in a caliber that delivers genuine long-range rimfire performance most rimfire shooters have never had access to in a semi-automatic format.

The Franklin Armory F17-L (0010056ODG) in 17 WSM is a proven platform and a capable tool for precision varmint hunters and serious rimfire shooters who want a reliable semi-automatic option built to centerfire-grade standards.
