Magpul PMAG GEN M3 20-Round AR-15 Magazine 5.56/.223 Black

The Magpul PMAG GEN M3 20-round magazine delivers enhanced reliability and durability for AR-15 platform rifles chambered in 5.56x45mm NATO and .223 Remington. This third-generation polymer magazine incorporates proven design improvements that address common feeding issues found in standard aluminum magazines.

What Makes This Different

The GEN M3 features an updated anti-tilt follower and constant-curve body geometry that ensures consistent feeding across various ammunition types and weights. Unlike traditional aluminum magazines, the impact-resistant polymer construction withstands drops on concrete and extreme temperature variations without cracking or denting. The magazine's self-lubricating properties reduce maintenance requirements while maintaining smooth operation through thousands of loading cycles.

Key Features

• 20-round capacity ideal for precision shooting and hunting applications
• Impact-resistant polymer construction rated for -50°F to 180°F operation
• Anti-tilt follower with four-way anti-tilt design prevents nose-diving
• Constant-curve body geometry optimizes spring tension and feeding reliability
• Textured gripping surface with dot matrix pattern for secure handling
• Over-insertion stop prevents magazine damage during tactical reloads
• Paint pen dot matrix for easy identification and marking

Field testing demonstrates consistent feeding performance with bullet weights ranging from 55 to 77 grains across multiple rifle configurations. The 20-round capacity provides an optimal balance between ammunition capacity and prone shooting comfort, making it particularly suitable for precision rifle work and hunting scenarios where magazine length matters. The magazine functions reliably in both direct impingement and piston-driven AR-15 systems.
