ProMag DRMA108 50-Round Drum Magazine 6.8 SPC AR-15 Polymer

The ProMag DRMA108 drum magazine transforms AR-15 platforms chambered in 6.8 SPC into high-capacity systems capable of sustained fire. This 50-round drum eliminates frequent reloading interruptions during extended shooting sessions. Built from DuPont Zytel polymer, the magazine delivers the strength needed for demanding applications while maintaining a weight advantage over steel alternatives.

What Makes This Different

Unlike standard 30-round magazines, this drum configuration provides 66% more ammunition capacity in a single loading. The DuPont Zytel polymer construction resists impact damage and environmental stress that can crack lesser materials. The drum design distributes cartridge weight evenly, reducing the forward pull that affects rifle balance with extended stick magazines.

Key Features

• 50-round capacity reduces reload frequency during competition and training
• DuPont Zytel polymer construction withstands temperature extremes from -40°F to 180°F
• Compatible with AR-15 platform rifles chambered in 6.8 SPC
• Drum configuration maintains rifle balance better than extended stick magazines
• Black finish provides non-reflective surface for tactical applications
• Spring-loaded follower ensures consistent cartridge presentation
• Removable base plate allows for cleaning and maintenance

The magazine functions reliably across various shooting positions and conditions. Competition shooters benefit from reduced stage interruptions, while training applications see improved efficiency through extended firing strings. The polymer construction resists corrosion from sweat and environmental moisture that can affect metal magazines. Range sessions become more productive when shooters spend time firing rather than reloading.
