Franklin Armory F17-L .17 WSM 20″ Piston Rifle

The Franklin Armory F17-L in .17 WSM is designed for shooters who want more performance from a rimfire platform. It uses the .17 Winchester Super Magnum cartridge, pushing a 20-grain bullet at over 3000 fps, making it effective for longer range shooting here in Utah. The F17-L’s piston system keeps the action clean and functioning reliably, even when using suppressors—a useful feature for those practicing sound suppression on the range or in the field.

It’s a good choice for anyone who wants a reliable, accurate, and suppressor-ready rimfire rifle. It’s also a good option for those wanting a step up from .22LR for longer range pest control on Utah properties.
