The ProMag DRMA80-FDE is a no-nonsense 55-round drum that feeds 5.7x28mm ammo through AR-style platforms. If you're running a FN 5.7 AR carbine and want to minimize time spent reloading, this drum delivers the capacity without the weight penalty that metal alternatives bring.
This magazine uses a proprietary DuPont Zytel polymer body paired with a blue steel upper magazine tower, combining real durability with practical weight savings. The feed lips are stamped and welded steel just like factory magazines, not stamped polymer, which means they can handle the workload. Inside you get an injection-molded follower and a heat-treated stainless steel spring that stays reliable through extended storage and repeated loading cycles. Everything comes together to create a magazine that works, not a gimmick that sits in your safe.
ProMag has been making high-capacity magazines since the 1990s and backs every magazine with a lifetime warranty against manufacturer defects. Their approach mixes traditional stamping and welding of heat-treated steel with precision injection molding, which shows in how these drums actually perform at the range. This isn't a budget compromise where you sacrifice function for capacity. The flat dark earth finish gives you a tactical aesthetic that coordinates with modern platforms while staying durable in the field.
This magazine is purpose-built for shooters who want extended capacity without the complexity of running multiple standard mags. Whether you're working through ammo at the range, practicing reloads, or just want the option of longer run times between magazine swaps, the 55-round capacity does real work.
Yes. The DRMA80-FDE is specifically designed for AR-style platforms chambered in 5.7x28mm, including FN 5.7 AR carbines. It uses standard magazine interfaces so it seats securely and indexes properly with your lower receiver. Always test function with your specific rifle before relying on it for any important use.
The drum format adds noticeable weight and bulk compared to standard 20 or 30-round box magazines, which is the trade-off for high capacity. The DuPont Zytel polymer helps keep the overall weight reasonable. Most shooters find the weight manageable for range sessions, though it does make rapid magazine changes slower than with lighter mags.
Periodically unload the magazine, give the follower and spring a quick visual inspection, and wipe any debris out of the drum. The stainless steel spring and injection-molded follower don't require lubrication. If you're storing it full for extended periods, ProMag springs are designed to handle that without losing tension.
Yes. Every ProMag magazine, including this drum, is backed by a lifetime warranty against manufacturer defects. If you have a feeding issue, failure of the spring, or defective follower, ProMag will replace it. This warranty gives you real peace of mind on a high-capacity magazine.
