Description
This ProMag drum magazine delivers solid capacity for range sessions and extended shooting without the weight penalty of larger magazines. The 15-round capacity hits a sweet spot between the compact 10-rounders and heavier 20-round drums, making it practical for shotguns where you need more firepower but don't want excessive bulk.
Hybrid Construction Built for Real Use
The magazine uses a proven hybrid design that combines a heat-treated carbon steel upper feed tower with an injection-molded polymer drum housing. This combination gives you the durability where it counts, the strength at the feed lips, while keeping overall weight manageable. The steel components handle the wear from cycling shells while the polymer body resists impacts and corrosion in field conditions.
Feeding You Can Trust
Internally, you get a heat-treated chrome silicon wire spring and an injection-molded polymer follower that work together to deliver consistent feeding every time you run the magazine. The precision engineering means tight tolerances and wobble-free seating when fully loaded, so your gun feeds reliably whether you're running drills or practicing for competition.
Built to Last
Made entirely in the USA, this magazine comes with ProMag's lifetime warranty against manufacturer defects. It's designed specifically for 2-3/4 inch shells, so make sure your shotgun takes that length before ordering. The 15-round capacity gives you significantly fewer reloads compared to standard magazines, letting you keep your eyes on target longer during range sessions.

Frequently Asked Questions
Will this 15-round drum work in my AR-style shotgun that's not an MKA 1919?
Most Turkish-made AR-style shotguns using MKA 1919-pattern magazines will work with this drum. G-Force, Radikal, and several other brands are compatible, but always verify your specific shotgun model first. MKA 1919 mags won't work in Saiga-pattern or other AK-style shotguns.
What shell length does this drum magazine require?
This magazine is designed exclusively for 2-3/4 inch shells. It won't accommodate 3 inch magnums or longer loads, even if your shotgun has a 3 inch chamber. Using the wrong shell length can cause feeding issues or damage.
How does this 15-round compare to the 20-round version?
The 15-rounder is lighter and more compact, making it better for tactical situations or when you want less bulk on your gun. The 20-rounder gives you more capacity but adds noticeable weight. The 15 is a practical middle ground for most shooters.
Is there a break-in period with this drum magazine?
Most users report the magazine runs reliably right out of the box. If you experience any initial resistance during loading, that typically smooths out after a few cycles. The lifetime warranty covers any manufacturing defects if you run into problems.
