Description
If you're running serious volume through your SCAR 17, this ProMag drum magazine cuts down reload time significantly. The 50-round capacity keeps you on target longer, whether you're at the range for practice or in a competition setting where every second counts. The drum design means you'll spend less time managing ammunition and more time focused on your fundamentals.
Hybrid Construction for Reliability
ProMag built this magazine with a proven formula. The body is constructed from DuPont Zytel-based polymer that handles the stresses of sustained fire, while the steel magazine tower and over-molded feed lips give you the feeding consistency you need when it matters. The injection-molded follower and heat-treated stainless steel spring work together to feed rounds smoothly. This combination of modern polymer and traditional steel components reflects decades of magazine design experience.
Made in the USA with a Lifetime Guarantee
This drum magazine is manufactured entirely in the United States and backed by ProMag's lifetime guarantee against manufacturer defects. The hand-crank loading mechanism is straightforward, making it easy to top off when you've got a pile of brass on the loading bench. The black polymer finish resists corrosion and blends with most modern rifle setups.
Built for Extended Sessions
Designed for range training and competition environments, this magazine reduces the frequency of reloads so you can maintain focus on shot placement and technique. The weight is manageable for the capacity you're getting, making it practical for longer training days without the fatigue of constantly swapping magazines.

Frequently Asked Questions
How do you load a drum magazine?
These drums use a simple hand-crank loading mechanism. Just rotate the hand-crank at the bottom and drop rounds into the tower opening. Keep rotating and feeding rounds until you reach capacity. It's straightforward and doesn't require any special tools or techniques.
Will this 50-round drum magazine fit my SCAR 17S?
Yes, this ProMag drum is designed to fit both the FN SCAR 17 and SCAR 17S platforms in .308 Winchester / 7.62x51mm NATO. It will fit your SCAR 17S without issues.
What makes the drum magazine heavier than standard box magazines?
The drum shape requires thicker walls and additional internal components to maintain capacity and feeding reliability in a circular design. The hybrid construction with both steel and polymer parts also adds weight compared to a flat box magazine. At 3 pounds loaded, it's substantial but manageable for training and competition use.
Is this drum magazine reliable for competition or training?
ProMag designed this magazine specifically for the SCAR platform with heat-treated springs and precision-engineered feed lips to ensure smooth feeding. Many use these for extended range sessions and competitive shooting. The hybrid steel and polymer construction is built to handle the demands of sustained fire without the constant reloading needed with standard capacity magazines.
