10/30 Magpul PMAG AR/M4 GEN M3 Window (.223/5.56)



CALIBER: .223 Remington / 5.56 NATO

CAPACITY : 10 ROUNDS (This is a 30rd magazine that has been permanently modified to 10rd capacity for restricted states)

OPTIONAL UPGRADE: (See drop down menu / subject to availability)
Install BLACK Ranger Plate +$5 (Ranger plate is BLACK and does NOT match the color of the magazine, Magpul does not make MCT color ranger plates)

NOTE: This magazine has been permanently modified to 10 round capacity by Calegalmag. Magpul does not manufacture 10/30rd magazines. We specialize in modifying high capacity magazines for restricted states. The modification is done internally with a proprietary limiter inserted into the magazine body and the floor plate is sealed to the magazine body with industrial polymer adhesive. This magazine can not be taken apart without destroying it.

The next-generation PMAG 30 GEN M3 is a 30-round (permanently modified to 10rd capacity by Calegalmags)
5.56x45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. Along with expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.

While the GEN M3 is optimized for Colt-spec AR15/M4 platforms, modified internal and external geometry also permits operation with a range of additional weapons such as the HK 416/MR556A1/M27 IAR, British SA-80, FN SCAR MK 16/16S, and others.

Similar to the MOE PMAG, the GEN M3 features a long-life USGI-spec stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding.

In addition, a redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons. Low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments, and a paint pen dot matrix has been added to the bottom panel of the body to allow easy marking by the end user for identification. The new floorplate aids extraction and handling of the magazine while providing improved drop protection, but is slightly slimmer than before for better compatibility with tight double and triple magazine pouches. An included pop-off Impact/Dust Cover can optionally be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit.
