D&H Industries Ar-15 300 Blk Aluminum Magazine W/ Red Follower 20 Rd
The D&H Industries AR-15 300 Blackout aluminum magazine is built for shooters running .300 BLK uppers who need reliable, durable ammunition storage. This 20-round mag pairs a tough aluminum body with a red follower, giving you both proven materials and easy visual confirmation of magazine status at a glance. D&H has long been known for producing dependable AR magazines that handle hard use without complaint—whether you're at the range, in the field, or testing subsonic loads.
The 20-round capacity strikes a practical balance for most hunting and tactical scenarios where you want more firepower than a 10-rounder but appreciate the slightly lower profile compared to a 30-round setup. The aluminum construction keeps weight minimal while maintaining the rigidity needed for reliable feeding, and the red follower is a simple detail that helps you manage your ammunition load at a glance.
If you're building or maintaining an AR platform chambered in 300 Blackout, having quality, purpose-built magazines in your loadout matters. D&H's no-nonsense approach to magazine design means you get straightforward functionality without gimmicks—exactly what most shooters need.

What's the difference between the 20-round and other capacities?
D&H offers this magazine in 10, 20, and 30-round configurations. The 20-round is a middle ground—more ammunition than a 10-rounder but with a lower profile than a 30-round mag, making it handy for hunting or situations where you want a balance of capacity and handling.
Why does this magazine have a red follower?
The red follower serves as a quick visual indicator of magazine status. You can see at a glance whether the magazine is loaded or empty without needing to shake it or look inside.
Is this magazine compatible with other AR calibers?
This magazine is built for .300 Blackout. While the physical dimensions may permit use with other calibers, it is designed and recommended for 300 Blackout ammunition only.
