Description
The Franklin Armory F17 magazine brings practical capacity to the .17 WSM platform without weighing down your rifle. Built from polymer, this 20-round magazine keeps ammo count high while staying lightweight, which matters when you're running and gunning across prairie dog country or spending long hours at the range.
Curved Design for Rimmed Cartridges
The F17 20-round magazine features a curved shape specifically engineered to handle the rimmed .17 WSM cartridge. Rimfire rounds need different magazine geometry than centerfire cartridges, and this magazine's design accommodates that reality. The anti-tilt polymer follower keeps rounds feeding consistently shot after shot, whether you're at the bench or in the field.
Works with Standard AR Platforms
Compatibility is straightforward with this magazine. It pairs with any standard MILSPEC lower receiver, giving you flexibility if you're building or upgrading an F17 system. The magazine simply drops into place and functions reliably without modifications. This versatility makes it a smart choice for keeping extras on hand without worrying about fitment issues.
Practical for Serious Shooting
Twenty rounds per mag means fewer reloads during range sessions, which translates to more shooting time and better practice reps. The polymer construction keeps the magazine durable through regular use without adding unnecessary weight to your rifle. For anyone running an F17, having a dedicated spare magazine ensures you're never caught short when it's time to get back to work.

Frequently Asked Questions
Will this F17 magazine work with other .17 WSM rifles?
This magazine is designed specifically for the Franklin Armory F17 system and works with any standard MILSPEC lower receiver. Other .17 WSM platforms like the Savage B.MAG use different magazine configurations, so compatibility is limited to AR-platform .17 WSM builds and Franklin Armory F17 rifles.
What makes the curved design important for this magazine?
The .17 WSM is a rimfire cartridge with a different shape than centerfire rounds. The curved magazine body accommodates the rimmed cartridge geometry to ensure reliable feeding and prevent jams. The anti-tilt follower works with this design to keep rounds stacked properly throughout the mag.
How many F17 magazines should I have for range sessions?
That depends on your shooting pace and preference, but having at least two or three magazines on hand gives you continuous shooting time without constant reloading. The 20-round capacity means each mag gives you solid trigger time before you need to swap, but most people like to rotate magazines to spread out cleaning tasks.
Is this polymer magazine durable for regular use?
Yes, polymer magazines from Franklin Armory are built to handle regular range use and field work. The material resists wear and keeps weight down compared to metal alternatives. Polymer followers and springs will eventually wear with thousands of rounds, but the magazine is designed for practical longevity in real-world conditions.
