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.

Does not hold as advertised
Color: Black
When the dash got hot from the sun, the glue gave way and everything ended up on the floor. Couldn’t send it back because the time limit had passed but I don’t use it

What a Cute Egg… Err Flower
Easy to install and easy to use! It’s as simple as turning two knobs to tighten onto the screen and placement of the arm. So adorable and has a strong magnet. Looks a little like an egg but who doesn’t love eggs and daisies?

Good mount for tesla cars
Build The design is a very different when compared to regular magnetic mounts. Some people will like it and others wouldn't. This looks like a daisy flower and can be mounted to any tesla car. Material The phone holder itself seems to be made of good materials, and offers a sturdy mount that remains secure in place. It does take some cranking to tighten and there is always a worry of over tighetening and breaking it. Functionality Installation and removal are straightforward and quick. The magnet provides a strong hold for my Samsung Ultra, and keeps it firmly in position during drives. Value for Money (VFM) At $16, the product offers good value, however at a tad higher price. Would recommend only to those who like the looks and need the mounting functionality.
