Frequently Asked Questions

Will this magazine fit my specific M1 Carbine, including commercial or imported variants?

This KCI USA magazine is designed to fit standard M1 and M2 Carbine rifles chambered in .30 Carbine, including USGI-spec and most commercial variants. It follows original M1 Carbine magazine dimensions, so it should seat and feed reliably in the vast majority of M1 Carbine platforms. If your rifle has been modified or is an unusual import variant, we recommend verifying feed geometry before purchasing.

Why does this magazine have a 15-round body but only hold 10 rounds?

This magazine uses a standard 15-round steel body that has been permanently blocked to limit capacity to 10 rounds, making it compliant with California's magazine capacity restrictions. The blocking is factory-installed and is not intended to be reversible. You get the full ergonomic profile of the original magazine with a compliant round count.

How does the cation electrodeposition coating protect the magazine?

Cation electrodeposition (also known as e-coating) applies a uniform, electrically bonded protective layer across all metal surfaces, including interior areas difficult to coat by other methods. This provides excellent corrosion and rust resistance, making the magazine well-suited for regular range use and long-term storage. It also contributes to smooth feeding by reducing friction on the follower and spring.

    Well constructed 15 round metal magazine that is updated to allow 10 rounds only. Perfect for California. Inserting rounds is easy. Fit was very good. Follower has bolt stop
