PMAG® AR/M4 GEN M3™ 5.56X45 NATO RIFLE MAGAZINE FOR AR-15 Reviews & Ratings

The next-generation PMAG AR/M4 GEN M3 is a 30-round polymer magazine for AR15/M4 compatible weapons chambered in 5.56x45 NATO / .223 Remington. Along with expanded feature set and compatibility, the GEN M3 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.

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

The PMAG GEN M3 also includes a redesigned bolt catch notch in the rear of the magazine that 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 give 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 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.

FEATURES

30 or 40-round reliability with no stoppages
Easy Identification - Use the paint pen dot matrix to easily identify your different loads when it's crunch time
Advanced follower- The anti-tilt, self-lubricating follower ensures a smooth feed and magazine reliability

Constant-curve internal geometry, over-travel insertion stop on the spine, and a long-life stainless steel spring ensure smooth feeding

Mostly great

Would have gotten a 5 but when i received my bundle of mags & was excited until i started loading them. There was 2 that had some sort of malfunction. As i was loading them they took 30 rds then i turned them upside down because i noticed some looseness & 3-4 rds just fell out. I tossed those 2 to the side & the rest loaded as designed.

It is what it is

Had to shave off the lip on the backside that contact the magwell. other than that it operated as it should

Almost Perfect

The Gen M3 is a direct answer to the (already minor) concerns about the Gen M2, creating a mag that trades the elder's weaknesses for a couple of its own. First off, some subtle revision of the geometry almost entirely prevents the phenomenon of the top cartridge popping out from an impact around the base, so there isn't likely to be any lost or half-ejected rounds in the event of a drop. It then streamlines the base plate to reduce its external lip, leaving more space between mags in a carrier to reduce "knocking" during movement, but sacrificing some of the M2's ease of removal, something the added bit of waffle texture at the bottom only partly makes up for. Additional textural tweaks deepen the pattern around the main body and add some ribs to the front for added traction. Finally, the bracing ribs at the top have been beefed up and a small ledge has been added to prevent over-insertion when the bolt is open - both serve to stabilize its position in the mag well, but also contribute to the increased difficulty of adding and removing the mag to and from a carrier; either way, it's still far better than a smooth GI mag from a gripping standpoint. The M3 is a bit pricier than its predecessor, but still quite affordable. And of course, it retains the durability, light weight, and great function that have made PMAGs the go-to for so many shooters. Thumbs-up.

At present seems to meet my expectations

I ordered the magazines (2-20 round P Mags) last Friday and received them Monday. WOW! That was quick!! At present they seem to load just fine and will be tested on Aug. 18th at a local Carbine match. I was recently asked why I would purchase 2, as I have several "old school" 20 round alumininum magazines. I responded by stating I use them when shoot prone (primarily at distance). One can also load the mags to capacity and they seem to function just fine. I will give a bit more KUDOS to Magpul in general as all existing alumininum magazines I own (30 rd- not 20 rd) have been outfitted with Magpul components and have always served my needs. All of my training/local carbine competition was conducted with the "upgraded" magazines. Not one problam that I can recall. Great stuff. I would recommend it (MagPul accessories etc) to anyone/everyone.
