Description

Everyone in the training industry knows Magpul and the fine accessories they make for ARs and shotguns. Magpul is best known for making the definitive modern AR-15 magazine, the PMAG. This video examines the 40 round PMAG.

Magpul PMAGs come in several different configurations, including with or without windows, and there have been a few generations of them. Generally PMAGs have been standard capacity (30 rounds) as part of people’s self-defense gear and professional uses, though smaller-capacity PMAGs exist for applications like hunting.

Higher-Capacity Magazines

The problem with high-capacity magazines in the past was they had reliability issues. Several different manufacturers made many different types but none were reliable enough to depend on in a defensive encounter. Until the Magpul 40 round PMAG.

40-Round PMAG

The 40 round PMAG Rob Pincus shows in this video has been used by him and students in his classes and has thousands of rounds through it, all of them trouble-free. Rob doesn’t recommend any product unless he and preferably several students have used it over a period of months. The Magpul 40-round PMAG performed flawlessly.

Because this PMAG holds 40 rounds, when inserted into the AR-15, it sticks out a couple of inches farther than a standard-capacity mag. Rob doesn’t feel this is an issue. Some people say the extra length makes it difficult to go prone with the 40-round PMAG, but prone is not a position anyone is likely to go into during a home-defense situation.

30 Percent More Rounds

The key point with the 40-round PMAG is that when you’re in any kind of situation where you are not carrying extra magazines on your body and you’re just grabbing the rifle — such as home defense — increasing your magazine capacity by 30% is pretty impressive.

It’s reliable, it’s from Magpul — consider the 40-round PMAG as part of your self-defense tools and accessories.

    That is fantastic, thanks for sharing. Have you run into any issues with state laws regarding magazine capacity?

Let's take a look at this 40 round PMAG made by Magpul. Now Magpul, of course, is well-known to everyone in the training industry who deals with AR-15s for sure. They make a lot of other accessories that are interesting for shooters. They started accessorizing shotguns as well a couple years ago. And, they're probably best known for their PMAG. Now they originally started just making extensions for magazines that would help you remove magazines, or find magazines, get 'em outta your pouches. And then they started making what really has become the definitive modern AR 15 magazine, the PMAG. Some of them have windows, some of them don't. They come in a lot of different configurations. There have been several generations of the PMAG, and generally they've been standard capacity. You know, of course there are also smaller capacity for different applications, like hunting. Or, if you wanted to go down to one of the smaller type AR mags like we had in the olden days, these 20 rounders, PMAGs will take care of that as well. But the 40 rounder is the one I want to talk about today. The 40 rounder is definitely very interesting to people. The problem with higher capacity magazines, the standard capacity magazine for an AR-15 being about 30 rounds, when we get to the higher capacity magazines, people always have reliability issues. There've been a lot of different brands out there, a lot of different types, that have claimed to be reliable. But in the training industry we see a lot of different things with a lot of different operators out on the range a lot of different types of rifles and not all of them work. So this 40 round PMAG is one that not only I, but several of my students, have been using for several months, or I can't even count how many hundreds, probably thousands of rounds have been through this particular magazine, and it's been flawless. So, before I recommend anything to anybody, I always like to make sure that I, and preferably a bunch of students in a training environment, have actually tested it out. And this 40 round PMAG certainly does pass muster, as far as that goes. And when you insert the 40 round PMAG into the gun, you're gonna see obviously, that it does stick out a little bit further than that 30 rounder does, but it's not anything gratuitous. You're gonna have like an extra couple of inches. There'll be people who tell you, "Oh, well, I can't go into a prone position," things like that. Fact is, the prone position, lying down flat on your stomach and shooting, isn't really a practical, defensive position. It's not one someone's likely to use inside of their home, or that a police officer's likely to use in a patrol rifle situation. So obviously, the extra two or three inches would make it a little bit harder to do that. You could take one of these extended base plates, specifically designed to be used as that rest, if you're gonna help that in terms of the prone position. Of course, these modern magazines don't suffer from some of the antiquated, older magazine problems of what happens when you impinge them, because they're looser and they move more when you go prone. So the extension, the extra length on this is not something that I'm really worried about. What I'm really worried about is getting an extra 10 rounds into the gun. And for a home defense situation, for patrol rifle situation, where you're very likely to just be grabbing the gun, and not be wearing a lot of kit, not be carrying a lot of extra spare magazines, increasing your magazine capacity by 30% is actually pretty impressive. So we go from 30 rounds to 40 rounds and it's incredibly reliable as you would expect from Magpul. The 40 round PMAG, consider it. Especially for your home defense guns that are staged, with only one magazine and patrol rifles, that'll be stored inside of a patrol vehicle the same way.
