View Full Version : New Magpul Gen M3 PMAG Overview

November 5, 2012, 06:33 PM

Well I'm still testing these mags (so far, so good) so no full review yet but here's a quick overview:

Things that are different:
-New polymer material for increased strength & durability. I can't feel a difference but Magpul says it's different
-Modified external/internal geometry so they can be used in multiple platforms to include the HK416, MR556A1, SA-80, SCAR 16/16s, M27 IAR, and possibly others
-The bolt catch cutout has been re-designed for use in the weapons above
-The slide has an overtravel stop to ensure it can't go to far into the magwell which can cause issues with the bolts on non-AR rifles
-Floorplate is slimmer to allow a better fit in dual mag pouches
-Dustcover doesn't clip on the bottom anymore; only on the top

Things that are the same:
-The proven stainless spring is the same
-The anti-tilt follower and curvature of the mag is the same. The follower is marked differently (see video) but is shaped the same
-Disassembly is the same; no tools required
-Still includes the dust/impact cover and it works on both the 'old' and new Gen M3
-Still made in the USA

Here's a video with some close ups, a bunch of additional photos at the end, and demonstrations of what I was talking about above:

Thanks for the pics and the review. How much more are these mags, or are they the about the same price as older Pmags?

They're the same price as the old (now called MOE PMags) PMags were. Those 'old' ones are on sale most places now. I got the non-window ones from Primary Arms for $14 shipped and the window ones are $16-18.

I just wanted to point out that since Magpul made the magazines a little bit "skinnier" and they still feel the same structurally that the new material must be a little bit stiffer. In other words they are getting the same stiffness with less material. I am no mechanical engineer but that is just an observation.

Also the Ranger base plates do not work on the new M3 magazines.

Correct. Magpul told me they'd have the M3 Ranger plates at SHOT show and they'd be on shelves by spring time frame.

Wow, I thought the old ones really thin.

Are the new ones less slippery or about the same?

They are really about the same. The ribbing on the front and back straps help a little when getting a purchase on the mag out of a magazine pouch, but that's about it from my shooting experience with them.

Nobody does polymer mags like the Russians. Those things are awesome. Metal molded in where it counts and very tough.
