Mauser Rimfire MP-40 .22 LR Magazine - 23rd Capacity, Black Polymer (Model 4400013)

The Mauser Rimfire MP-40 .22 LR magazine in black polymer is a high-capacity feeding solution for owners of the Mauser MP-40 rimfire platform. Built to reliable Mauser standards, this 23-round magazine lets you spend more time shooting and less time reloading—whether you're training at the range, running a .22 LR plinker for small-game hunting, or just stretching a trigger session at the steel. The polymer construction keeps things light and durable without the corrosion concerns of bare metal, and the black finish matches most modern rimfire setups.

Capacity matters in a magazine, especially in .22 LR where rounds are plentiful and the recoil is nonexistent. At 23 rounds, this magazine maximizes your trigger time between reloads. The polymer body is field-proven in applications where weight savings and weather resistance make a difference—think truck racks, range bags, and backup kit situations where steel mags add unnecessary bulk.

Whether you're building out a MP-40 platform or stocking spares for regular range use, this Mauser-branded magazine is engineered for the rifle it's designed for. Keep one in the rifle and a couple in your kit; 23-round capacity at this price point is practical redundancy.

Frequently Asked Questions

Will this magazine work with other .22 LR rifles?

This magazine is designed for the Mauser Rimfire MP-40. Magazine compatibility varies by platform; always verify fit and function with your specific firearm before relying on it in the field.

You receive the magazine only. Follower, spring, and any other internal components are part of the assembled unit.

Is the polymer durable enough for regular use?

Yes. Polymer magazines are standard in modern rimfire platforms and handle routine range use, cleaning, and storage without issue. The material resists corrosion better than bare steel in damp conditions.

What makes 23 rounds the capacity for this magazine?

The 23-round capacity is engineered by Mauser for reliable feeding in the MP-40 platform. It's a proven balance between capacity and feeding geometry for .22 LR rimfire rounds.
