The next-generation PMAG 40 GEN M3 is a 40-round 5.56x45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. Along with an expanded feature set and greater compatibility, it incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability that 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.

The PMAG 40 GEN M3 features a long-life stainless steel spring, a four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly for easy cleaning.

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, easy to disassemble flared 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.

Perfect for hot summer days
I have purchased 8 pairs of these shorts ★★★★★. Summers where I live have average daily highs of 90° and high humidity. US medium normally fits me perfectly, but I buy 2XL/34-36 in these shorts to keep the fabric away from my skin on hot days. The 34-36 are not baggy and look nice. These short are perfect. Thin stretchy fabric makes them very wearable. Material quality is exactly what I want. The pockets hold everything I want to carry. The price is right.

Pretty nice for a China product!
These are very nice polyester, light weight shorts. Of all the Chinese options on Amazon Ive ever ordered, these are probably the nicest ones. The fit is good, and they're comfortable. Reference- I'm 6', 200lbs, athletic build. I bought size 34.
