This is the Franklin Armory F17 SPR .17 WSM 10-round magazine. 

If you need a few spare magazines for your Franklin Armory F17, you’re in the right place!

This lightweight but durable polymer magazine keeps ten rounds of .17 Winchester Super Magnum ready to go at all times. Thanks to the side-facing witness windows, you’ll never have to guess how many of those ten rounds are left. 

Whether you’re protecting your farm from unwanted four-legged visitors or spending your weekend plinking away at some steel targets, this factory magazine from Franklin Armory is just what you need.

Since they only hold ten rounds, you might as well add a few to your cart!
