Description
If you own a vintage Remington 511, 513, or 521, having a dependable spare magazine is one of those essentials that makes range days way better. This Triple-K reproduction is manufactured from heat-treated blued steel and works as a straightforward replacement for the originals that have either worn out or simply gone missing over the decades.
Triple-K's Solid Construction for the 511/513
The magazine is built entirely from steel, which means it'll handle the day-to-day wear without falling apart. The heat-treated body combined with a stainless steel follower and steel base plate gives you the kind of durability these rifles deserve. It's bench-tested before it ships, so the feed geometry and spring tension are sorted from the start.
10-Round Capacity Built for Extended Shooting
With room for 10 rounds of .22 LR, you can spend more time actually shooting and less time loading mags. Whether you're out for small game hunting or hitting targets at the range, that extra capacity makes a real difference in how much you can accomplish before needing to reload.
Proper Fit for Multiple Remington Models
This magazine works with the Remington 511, 513, 513T, and also fits the Nylon 11. It's compatible across several variants of these classic rimfire rifles, making it a versatile choice if you've got more than one rifle in your collection.

Frequently Asked Questions
Will this magazine fit my Remington 511, 513, or 521?

Is this magazine made in the USA?
Yes. Triple-K manufactures this magazine in the United States using heat-treated blued steel construction with a stainless steel follower for reliability and longevity.
