If you’re looking for the utmost in rimfire velocity to knock out groundhogs, prairie dogs and even coyotes, the Franklin Armory F17-L will bring it. Built on the AR platform and designed specifically for the .17 Winchester Super Mag., the F17-L uses a gas-piston operating system paired with a rotating, locking bolt—similar to what you’d find in a piston-driven centerfire AR.
The high-velocity, high-energy .17 Winchester Super Magnum rimfire is a welcomed cartridge for many wishing to engage everything from destructive rodents to marauding coyotes, especially in regions where centerfires are noisy, frowned upon or even illegal. But finding a rifle to shoot the world’s fastest rimfire has been a challenge.
In August, Savage Arms issued a recall notice on the rifle bolts of its popular B.MAG model, chambered in .17 WSM. Our own Karie Thomas walks you through the process of repairing your rifle—using only Savage's free retrofit kit—in the video provided here.
