Description
The Magpul Minus 10 Round Limiter is a simple solution when you need to temporarily reduce magazine capacity. Built as a polymer insert, it slides into compatible PMAG LR/SR Gen M3 magazines to bring them down from 20 or 25 rounds to 10. The entire install takes about a minute with no tools required, and there's no permanent damage to your magazines.
Installation and Reversibility
No tools, no mess, and fully reversible. Pull off the magazine floorplate, slip in the limiter, and snap the floorplate back on. You can remove it just as easily whenever you want, which makes this ideal for anyone switching between different shooting scenarios. Whether you're heading to the range, out hunting, or handling your mags for transport, this takes seconds to swap in or out.
Built for Real-World Use
Magpul made these with durability in mind. The durable polymer construction handles regular installation and removal without wearing out, so you can swap these in and out season after season without worrying about degradation. This is exactly the kind of product that works the same way on day one and day 100. The three-pack gives you flexibility to equip multiple magazines or rotate them as needed.
What Works and What Doesn't
These limiters are designed specifically for 20 or 25 round PMAG LR/SR Gen M3 magazines in 7.62×51 NATO. They work great with AR-10 platforms and other rifles chambered in .308 Winchester or 7.62 NATO. The limiter sits at the base of the magazine and physically blocks rounds from loading past 10. It's a proven, straightforward design that just works when installed correctly on the right magazines.

Frequently Asked Questions
Will this Minus 10 limiter fit my PMAG magazines?
Yes, but only Gen M3 LR/SR PMAGs in 20 or 25 round capacity chambered in 7.62×51 NATO (.308 Winchester). These are specifically designed for larger caliber AR-10 platforms. If you have AR-15 magazines or older Gen M2 PMAGs, you'll need a different limiter model.
How does the installation work on the PMAG Minus 10 limiter?
Installation is straightforward and tool-free. Simply remove the magazine's floorplate, slip the polymer limiter into the magazine body, and snap the floorplate back on. The entire process takes about a minute, and you can remove and reinstall it whenever you need without damaging your magazine.
Can I permanently attach this limiter to my magazine?
The limiter installs reversibly by design, but some users choose to permanently secure it with epoxy or a rivet if required by their situation. The limiter itself doesn't come with permanent attachment hardware, so any permanent installation would need to be done separately if desired.
What capacity will my magazine hold with the Minus 10 limiter installed?
A standard 20-round PMAG becomes a 10-round magazine, and a 25-round PMAG becomes a 15-round magazine when the limiter is installed. The limiter physically blocks the spring from loading rounds beyond the 10-round point.
