High-capacity magazines play a specific role in defensive setups where sustained fire and quick reload strategies are part of an overall plan. For operators and serious enthusiasts who want a durable, lightweight option that keeps weight down without sacrificing capacity, a polymer drum can be a practical addition to the gear bag.
PROMAG AR-15 is an AR15 drum magazine constructed of polymer and compatible with ColtSMG rifles. 
Design and materials
The PROMAG AR-15 uses molded polymer construction to reduce weight while maintaining a rugged exterior. Polymer components offer corrosion resistance compared with traditional steel drums, and they are less prone to surface rust in humid or coastal environments. The description specifically highlights polymer construction — a key benefit for users who carry extra magazines during training or operations where every ounce matters.

Why polymer matters
Polymer absorbs impact differently than metal and often sheds dirt and grit more readily. For field maintenance, this translates to easier cleaning and fewer corrosion concerns. The PROMAG AR-15 balances robust geometry with lightweight materials to keep handling predictable during transitions.
Shop this product to view specifications and see current pricing on the product page; retail price is listed at $76.99.
Compatibility and practical use
The product description calls out compatibility with ColtSMG rifles, which means fitment has been considered for systems that follow Colt-style AR platform patterns. Users planning to run this drum on an AR-pattern rifle should verify magazine catch engagement and feed-lip alignment during function testing. Because the model listing is noted as Various, there are configurations intended to fit common AR platforms while supporting ColtSMG compatibility.
Field considerations
Load and function-test each drum in your rifle before relying on it in a defensive scenario. Polymer drums require the same basic preventive maintenance as other magazines: inspect springs and feed lips, clear debris, and practice transitions to understand weight and balance changes when loaded.
For buyers who want a lightweight, polymer-built drum that lists compatibility with ColtSMG rifles and carries a price of $76.99, the PROMAG AR-15 is a practical choice to evaluate for high-capacity needs.
