About this product

Available for delivery across the United States.
The Franklin Armory F17-X 16″ .17 WSM 20rd is a piston-driven rimfire rifle engineered for shooters who demand flat trajectories and suppressed-ready reliability without manual gas tuning. Chambered in .17 Winchester Super Magnum, this semi-auto runs Franklin Armory’s proprietary OPS piston system—self-regulating for suppressed or unsuppressed fire—and mates a 16-inch precision barrel (1/2-28 threads) to an optic-ready aluminum receiver with an M-LOK handguard and integrated barrier stop. It ships with a 20-round detachable magazine, delivering 3,000 fps velocities and sub-MOA potential from a lightweight, low-maintenance platform.

Key Features
- OPS Piston System – Self-adjusts between suppressed and unsuppressed firing without any gas port swaps or tuning. This means zero added fouling in the receiver and cleaner cycling across 1,000+ rounds.
- 16″ Precision Barrel (1/2-28 Threaded) – Factory-crowned for accuracy and threaded in the common 1/2-28 pitch, so you can direct-thread a suppressor or mount a brake without adapter headaches. Keeps the rifle compact while still squeezing full velocity from .17 WSM.
- M-LOK Handguard with Integrated Barrier Stop – The handguard includes a built-in stop that prevents the rifle from sliding forward on barricades or bags, which matters when you’re shooting from improvised positions at distance.
- Optic-Ready Aluminum Receiver – No iron sights to remove—just mount your preferred optic directly to the receiver. The rail is integral, keeping zero consistent even after disassembly.
- 20-Round Detachable Magazine – Double-stack design gives you 20 rounds of .17 WSM on tap, enough for multiple target engagements or varmint control without constant reloads.
Who It’s For
This rifle is built for long-range rimfire shooters who want a flat-shooting, low-recoil option that stays clean with a suppressor. It’s also ideal for varmint hunters who need a semi-auto that can handle rapid follow-up shots on coyotes or prairie dogs out to 300 yards, without the weight or gas system maintenance of a centerfire.
Pros / Cons
- Pro: Sub-MOA accuracy from a factory barrel with match ammo. Per Franklin Armory specs, the F17-X consistently prints 0.75 MOA at 100 yards with 20-grain loads.
- Pro: Self-regulating piston system means no fiddling with gas settings when switching between suppressed and unsuppressed configurations.
- Cons: .17 WSM ammunition is less widely available than .22 LR or .22 Magnum, so you may need to order online or stock up in advance.
