ATI ATIMAM2B30 AR-15 Magazine 30rd 223/5.56/300 Blackout Polymer

The ATI ATIMAM2B30 delivers reliable feeding for AR-15 platform rifles across multiple calibers without the premium price tag. This 30-round magazine handles 223 Remington, 5.56x45mm NATO, and 300 Blackout cartridges with consistent performance. Built from impact-resistant polymer, it provides shooters with an affordable backup or replacement magazine option.

What Makes This Different

Unlike steel magazines that add unnecessary weight, this polymer construction reduces overall rifle weight by approximately 3 ounces per magazine. The anti-tilt follower design prevents double-feeds and misfeeds that plague cheaper alternatives. Internal geometry accommodates the varying case dimensions between 223 Remington and 300 Blackout without requiring separate magazines for each caliber.
