The Franklin Armory F17-L Upper Kit (brand part number 0040073BLK) is a 20-inch upper build kit chambered in .17 Winchester Super Magnum for the Franklin Armory F17 straight-pull platform, finished in black and set up for 10-round capacity. The .17 WSM cartridge pushes a tiny, ultra-fast rimfire bullet at velocities that outrun most centerfire varmint rounds, making the F17 platform a favorite for precision varmint and small-game hunters who want a flat-shooting, low-recoil rifle with a distinctive straight-pull action. This kit mates to a Franklin Armory F17 lower to complete the build.

Frequently Asked Questions

Is this a complete rifle? No, this is an upper build kit for the Franklin Armory F17 platform. It requires a compatible F17 lower to complete the rifle.

What makes the F17 platform different from a standard AR? The F17 uses Franklin Armory’s proprietary straight-pull action rather than a standard AR-15 direct impingement or piston system, paired specifically with the .17 WSM cartridge.

Why choose .17 WSM for varmint hunting? It delivers an extremely flat trajectory and high velocity with minimal recoil, making fast follow-up shots on varmints and small game easier than with most centerfire options.
