Magpul PMAG GEN M3 30rd Magazine 5.56 NATO AR-15 Window Black

The Magpul PMAG GEN M3 30-round magazine with capacity window delivers enhanced reliability and visual ammunition tracking for AR-15, M16, and M4 platforms. This third-generation polymer magazine addresses common feeding issues while providing instant capacity verification through its integrated window design.

What Makes This Different

The GEN M3 incorporates an over-insertion stop tab that prevents magazine damage from excessive insertion force, a common issue with standard USGI magazines. The capacity window features clear polymer construction with printed round count indicators, eliminating guesswork during tactical reloads. Advanced polymer construction reduces weight by 20% compared to steel magazines while maintaining superior impact resistance.

Key Features

• Translucent capacity window with round count markings for instant ammunition verification
• Over-insertion stop tab prevents magazine damage and ensures proper seating
• Anti-tilt follower with constant curve geometry eliminates feeding malfunctions
• Ribbed gripping surface and flared floorplate enable positive handling in adverse conditions
• Paint pen dot matrix on both sides allows custom marking and identification
• Compatible with 5.56x45mm NATO and .223 Remington cartridges
• Fits all STANAG 4179 magazine wells including AR-15, M16, M4, HK416, and SCAR 16S

Field testing demonstrates consistent feeding through 10,000+ round cycles without spring degradation or follower wear. The magazine maintains functionality in temperature extremes from -50°F to 180°F and survives repeated drops onto concrete from 6 feet. Law enforcement agencies report 99.8% reliability rates in duty applications, while competitive shooters appreciate the window's ability to track round count during rapid-fire stages.
