MagBlock PMAG 30 MCL 10/30 [10 round Limiter]

Product Description

The MagBlock PMAG 30 MCL 10/30 is a magazine capacity limiter that restricts a standard 30-round PMAG to 10 rounds. It installs inside the magazine body to create a physical block, bringing the magazine into compliance with state capacity restrictions or hunting regulations that limit semi-automatic rifles to 10 rounds.

This PMAG 10/30 limiter offers a cost-effective alternative to purchasing dedicated 10-round magazines. You retain the full-size magazine footprint for a consistent grip and manual of arms.

The MagBlock is designed for shooters who cross state lines into restricted jurisdictions, hunt in areas with magazine capacity limits, or simply want a reversible compliance solution.

How the PMAG 10/30 Conversion Works

A magazine block sits inside the magazine tube and physically prevents the follower from traveling below the 10-round position. The result is a permanent reduction in capacity unless the block is removed.

Installation typically requires disassembly of the magazine floor plate and insertion of the limiter above the spring and follower. Once installed, the magazine functions normally but stops accepting rounds after the tenth.

Some jurisdictions require permanent modification. Others allow removable limiters for temporary compliance. Send us a message to confirm whether this configuration meets your legal requirements before purchasing.

PMAG Round Limiter vs. 10-Round Magazines

Dedicated 10-round PMAGs are shorter and may not lock the bolt open on some rifles due to reduced spring tension. A 10/30 PMAG using a limiter retains the full-length spring and original magazine height, which can improve last-round bolt hold-open reliability.

The trade-off is added weight from the unused portion of the magazine body. For travel or hunting, a limiter offers flexibility: you can reverse the modification if you return to an unrestricted jurisdiction, though doing so may not be legal in all states.

Frequently Asked Questions

Q: What is a 10/30 PMAG?

A: A 10/30 PMAG is a 30-round magazine that has been restricted to 10-round capacity using an internal limiter or block. The designation means 10 rounds in a 30-round magazine body.

Q: Can you remove the 10 round limiter from a PMAG?

A: Physically, most PMAG round limiters can be removed by disassembling the magazine, but doing so may violate state or local laws if you are in a restricted jurisdiction. Check your local regulations before attempting removal.

Q: Does the MagBlock fit all PMAG 30 models?

A: The MagBlock PMAG 30 MCL 10/30 is made for PMAG 30-round magazines, but internal dimensions can differ between generations. Send us a message to confirm fit for your specific PMAG model.

Q: Why use a limiter instead of buying a 10-round magazine?

A: A limiter allows you to keep your existing 30-round magazines and convert them as needed for travel or hunting. It also maintains the full magazine length, which can improve bolt hold-open function compared to shorter 10-round magazines.

Q: Is the MagBlock PMAG 10/30 legal in restricted states?

A: Legality depends on your state and local laws. Some jurisdictions allow removable limiters, while others require permanent modification or prohibit possession of the original 30-round magazine body entirely. Confirm compliance with local counsel or your state attorney general before purchase.
