The KCI USA M1 Carbine Magazine in 15-round capacity is a modern-production magazine purpose-built for shooters keeping their M1 Carbines fed and ready. Whether you're running a vintage military rifle or a civilian variant, this straight-wall magazine delivers the straightforward reliability that made the M1 Carbine an icon—without the complexity or cost of NOS (new old stock) alternatives. KCI manufactures these magazines fresh, not as refurbished units, so you're getting new-production quality every time.
Built with a blued, heat-treated steel body and fitted with a chrome silicon steel spring, this 15-round M1 Carbine magazine is engineered to handle regular range work and field use. The removable steel base plate lets you field-strip the magazine for cleaning, and the bolt-hold-open follower locks the bolt back on the last round—a practical feature that tells you at a glance when you're running dry. The straight-wall design and compact footprint are exactly what mil-spec and most civilian M1 Carbines demand, so compatibility is straightforward across the platform.
At this capacity and build quality, a single magazine is just the start. Savvy M1 Carbine shooters stock up on these—they're affordable enough to build a rotation and keep your shooting session uninterrupted. Load them, run them hard, and trust KCI's reputation in the surplus and civilian market to keep your carbine in the fight.

Frequently Asked Questions
Will this KCI magazine work in my M1 Carbine?
Yes. This magazine fits all mil-spec M1 Carbines and most civilian variants with the standard M1 Carbine magazine well. If you're unsure about a particular rifle, verify your carbine's spec sheet or manual beforehand.
What's the difference between this new-production magazine and old surplus magazines?
KCI manufactures these magazines fresh—they're not refurbished, rebuilt, or leftover military stock. New-production means consistent quality control and no wear from decades of storage or military service. You get a like-new magazine ready to run.
Does this magazine have a bolt-hold-open feature?
Yes. The steel follower includes a bolt-hold-open function, so the bolt locks back on the last round. This gives you a tactile and visual signal when the magazine is empty.
Can I take this magazine apart to clean it?
Yes. The removable steel base plate allows you to field-strip the magazine for cleaning, spring maintenance, and inspection.
