Magpul PMAG 5 7.62 First Look

In Blog by Rich10 Comments

I wanted to do a quick writeup and post a short video on Magpul’s new PMAG 5 7.62 magazine. If you haven’t been following the development of the PMAG 5 7.62, it’s Magpul’s newest magazine to hit the market. Only instead of being produced for autoloading platforms like the AR15 and AR10, this one is designed to target the bolt action rifle market! The PMAG 5 7.62s will work with any Accuracy International compatible bottom metal or chassis systems. If you don’t see the advantage here, I’m not sure why you’re reading this…because it’s obvious to anyone in the Precision Rifle Community. The Magpul PMAG 5 7.62 magazines are going to be literally half the cost of the metal Accuracy International magazines. The question is, will they hold up?

Magpul PMAG 5 7.62

Magpul has been working on this for a while. They released their Hunter 700 stock for the Remington 700 action earlier this fall and most of the first run sold out quickly. They also have released an add on for their Hunter 700 Stock that converts it to a magazine fed rifle. Great feature, and a marketing opportunity for Magpul. If their new stock makes magazine feeding possible, why not produce a magazine as well? That’s exactly what they did. The PMAG 5 7.62 runs right about $33 USD which is half the cost of the AI brand 5 round magazines which run about $66 USD from Mile High Shooting. The PMAG 10 7.62 is slated to run about $39.95 which again, is half the cost of the AI brand equivalent.

PMAG 5 7.62 Impressions

I like the PMAG 5 7.62 a lot! I load my ammo for my 308 on the long side for a few reasons. For starters, when I worked up the load, I was going for maximum performance. Load the highest BC bullet I planned to use, as long as I could, in order to keep case capacity as high as possible for more powder and lower pressure. What I got was a 178gr Hornady HPBT with a 0.53 G1 ballistic coefficient moving at 2700fps with single digit standard deviation. It’s a great performing load in my 308 Winchester. However, loading ammo long can have it’s downsides. Particularly when it comes to feeding from a magazine. The longer the bullet gets, the less reliable the feeding. Mine feed 100% reliably, however the first few rounds in a full 10 round AI magazine are tight, and they can make contact with the feed ramp and stick a little.

Side by side, both the AI magazine and PMAG 5 7.62 both have the same internal dimensions and handled my long 308 rounds without any issue, in fact, they fed better than the AI magazines!

I tried running the same rounds, already loaded for my 308 through the PMAG 5 7.62 magazine and they fed flawlessly! Silky smooth without any issues, sticking, etc. It fed the five rounds from the magazine like greased lightning. Truly impressive! I want to point something out here that you may have missed. I said the rounds are loaded long! They are! About 0.050″ longer than the specification for 308 Winchester which is 2.810″…mine measure over 2.860″ in cartridge overall length. Not only do they fit the PMAG, but they feed perfectly despite being loaded long. The reason that’s a big deal is because for a long time nobody thought you could produce a polymer magazine that didn’t restrict hand loaders to mag length without compromising the strength of the magazine somehow. Whether the PMAG 5 7.62s hold up to abuse or not is yet to be seen, but I’m excited by the prospect already and from what I’ve seen so far!

PMAG 5 7.62 Predictions

So how do I think this is going to pan out? Well, I think these are going to be a real hit and it’s going to be a huge thing for the precision shooting community. Accuracy International has long been the standard all other magazines are measured by in the precision shooting world. This is for good cause. The Accuracy International magazines are a proven product. They work new, old, dirty, clean, hot, cold, whatever, whenever, and wherever you use them. That’s not to be taken lightly, especially for guys in our Military and Law Enforcement communities. However, Magpul has built a reputation on providing excellent products at more affordable price points that are every bit as reliable and trustworthy as the metal products they compete with.

These long 308 Winchester rounds fit and fed flawlessly!

I think these new PMAGs are going to do for the Tactical Rifle guys what the original PMAGs did for all the AR15 guys. It’s going to be a reliable product that costs a fraction of the products on the market already. In the end, competition is good for the industry and the consumer. It forces competing companies to offer aggressive pricing and to search for ways to produce higher quality products at lower prices. The consumer always wins when the market competes. The PMAG 5 7.62s I’ve been playing with have been really cool so far. They feed better than I could have hoped for and with the identical internal dimensions to the AI brand magazines, nobody has to redo any of their load development work to use them. If you’ve got a load worked up that fits an AI mag, it should fit the PMAG 5 7.62 also. It just might feed better, too!

You can modify the follower to accept a 6th round…

Wrapping Up

I’ll be revisiting this topic again in the future after I’ve had some time to put some rounds through these PMAG 5 7.62s and their 10 round brethren when they’re finally released. In the mean time, I did a quickie video to show how smoothly they feed even with my longer 308 rounds in the videos below! I want to see how they hold up over a few months of use, getting dropped, kicked, and stepped on in the mud. Things that most magazines endure during day to day operations. However, I really like what I’ve seen so far just playing with these for a couple days and wanted you guys to have some information on how they look. We all work hard for our money and part of my job with this site is making sure you guys have the information to make intelligent purchases with your hard earned cash!

      2.885 is the max internal length, my 308 rounds measure 2.862 and feed perfectly!

      FYI, Brownells is now taking pre-orders for the 10 round version of this magazine, so I’d be willing to bet they’ll be available shortly! Get ’em while they’re hot…

  1. I bought the Magpul bottom metal and an extra mag for about $100 shipped. I was able to make some modifications and install it on a B&C stock. I have been wanting to add a detachable magazine system to my Rem 700 for awhile, this made it cheap enough that I just couldn’t say no.

    I run into an occasional issue of the bullets catching on the feed ramp when the magazine is first inserted. I’m not sure if it is from an error with the install since I modified the stock and bottom metal myself, or due to another issue. The 5 round magazines are easy to load and they feed very smooth. I’m definitely happy with the purchase.

      How long are the rounds loaded? That’s likely the issue, there’s a fix but it’s a permanent modification to the action.

      1. I had to go back and look at my notes, the 178 Amax was loaded to 2.825″ I am hoping to attend my first match in Pueblo this weekend, so I’ll see how it works.

      I am, Jerry! No issues to speak of, the only problems I’ve seen people mention are with non Remington actions.

  2. I want a 20 round mag for for bolt gun other than a ruger precision. I have been told that don’t make in aics style mags. Can anyone help with this? I shoot standing up, not laying down, I don’t care how long the magazine would be.

      Seekins and MKM Machining make extensions but 14rds is probably the best you will be able to do… nobody makes a 20.
