Magpul PMAG 20 AR/M4 GEN M3 — 5.56 NATO, 20-Round

Same Gen M3 magazine, twenty rounds instead of thirty. The short body is the point — it lets you get properly low prone, or sit flat on a bench, without the magazine propping the rifle up.

• Caliber: .223 Remington / 5.56 NATO
• Capacity: 20 rounds
• Material: Black polymer
• Fits: AR-15 / M4 pattern rifles
