Product Details The next-generation PMAG 40 GEN M3 is a 40-round 5.56×45 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. The PMAG 40 GEN M3 features a long-life stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly to ease 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. 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. Made in U.S.A. FEATURES Next-generation impact and crush resistant polymer construction Modified dimensions allow for wider compatibility with non Colt-spec platforms Constant-curve internal geometry for smooth feeding Anti-tilt, self-lubricating follower for increased reliability Long life stainless steel spring Over-travel insertion stop on the spine Ribbed gripping surface and new aggressive front and rear texture for positive magazine handling Paint pen dot matrix panels on the bottom of the body to allow for identification marking Flared floorplate aids magazine handling and disassembly yet is slim enough for use with many double and triple pouches Pop-off Impact/Dust Cover to minimize debris intrusion and for ammunition protection in storage and transit

Very pleased with this magazine. I’ve only been able to use it once and it worked well. An extra 10 rounds is always nice!
Ran amazing!Magpul 40 rounds
Magazine runs flawless no hick up. Awesome product!!!
Love the 40s
Anything Magpul is made well and reliably. I love them all.
Looks good
Have only owned this for a short time now. So cannot comment on extended use or condition of springs after long-term use. So far, I see no issue with functionality, and the additional length is not terribly more inconvenient than a 30-round pmag. Fit and finish looks good. I hope the industry will gradually move towards 20-round and 40-round pmags in the future. You either have… read more a nice reduced profile clearance, or you don't. So one might as well go with a 20 or a 40. Several other manufacturers are making these, but I would like to see more of these, so that mass production increases and hopefully becomes the de facto standard for AR-15s. Glad Magpul is putting these out.
40 for more fun
They work great, a lot of fun.
Good Magazibe for the money
