Pmag Spring and Load?

[Heavy_Metal]

@mmike87

I absolutely have one P-mag that will not seat with 30 on a closed bolt. My other 7 do - it’s just one mag. It otherwise functions perfectly.

What is the mould date on the side of the mag? You heard about the bad mag body exchange?

@demigod

You guys are going to keep talking about these damned things til I buy some aren’t you? :mad:

PMAGS for M-Plates
Seriously, you should try a couple. The windows are a good feature.

@Shihan

Good info thanks. In regards to the CS springs did they just rust or did they break?

Spring broke near the attachment piont to the follower.

That’s interesting . . . just don’t drop them on their feedlips. The mag was the 7/07 date. Magpul replaced them but I’m surprise it didn’t do better.

Wow, that is an interesting pic. Give us a call and we’ll switch it out for you. How did that happen? In all of our testing the only time I saw a break like that was from 30+ feet loaded!

Im glad I checked before I replaced with CS springs, thanks.

It was more like 5 ft loaded falling on the edge of the feedlips and Magpul already replaced them.

That type of fall would definitely ruin a USGI mag too. Dents on the back corners of USGI mags screws up the top round alignment and creates feeding issues.

I glad you did, too. I was seriously considering putting some Wolff springs in but I’ll save the money for the PMag Ranger plates. Although, with the type of open top pouch I use and the PMag design, I’m not sure I really need RP’s for these.

I routinely drop my beater Pmag on the lips when demonstrating the abuse it can handle, but I cheat and leave the protective cover on.

Im not sure if that counts lol.

I’ve tried the same fall (and higher) w/ USGI several times and they worked just fine, just a little banged up but functioned just fine.

When I recd the replacements, did the same thing w/ the cover on and the same breakage occurred.

I just dropped a 08/07 PMAG (tan non windowed loaded with 30 rds of Mk262) off the roof of our villa in Baghdad onto pavement lips first.

I had intially dropped it from 8 feet onto the marble floor - but decided it was not high enough.

First time from about 20 feet it bounced no issues

Second time - it spit a round of 262 out -

I will shoot it tomorrow - but the follower runs fine - and it took the 30th round back.
It shows some road rash on the lips - and will post a pick tomorrow - I’m off to bed soon.

Good test Kevin. Awaiting pics.

Kevin it must be nice to drop MK262 off buildings, here if we can find any its about Zillion bucks a boz.

@7KOPPER

I’m polite and professional 100% of the time you ass holes. And what KB said, 30 rounds. Will fit 31 but you’ll have the same issues with 31 in a PMAG as you do with 30 in a USGI. Load em up to 30 and and give the top round a push down, should travel 5-6mm to allow insertion on a closed carrier.

As far as springs, CS were originally spec’ed on the PMAG. The CS’s failed something awful on the salt spray test, they broke where the SS had zero and I mean zero corrosion.

BTW, several accounts of seven figure round counts through 02/07 PMAG’s with original springs. I’m guessing they are a little soft now but the user (US Army) says the run great in FA and has had minimal malf’s!

With the SS springs you guys used could you leave a new mag loaded indefinetly?

Update, with the pics

Pics of mag dropped last night, small hint of “roadrash”

I did some more drops today - just to see.

Height was 22ft. Same mag as before - drop lip first.
This mag was dropped two more times today

first drop - spit one round again.

second drop - spit 4 rounds - and spine cracked as seen.

Mag will now only hold 28 rds (it takes 30 then one will pop out - then the next over a few minutes)

However I found you CAN load 30rds - and place it in the mag well -and the mag well hold it together - that it feeds and cycles all 30 rds.

There is NO WAY in hell a USGI or HK “high reliability” mag will do that – the lips would be toast - and the system worthless.

This mag (08/07) will be swapped out for a 06/07 body I had from the replacement bodies magpul sent me.

Oh and I verified that 3 more M4 lowers fit with 04-08 built PMAGS today

maybe I’m just luck

Kev, your experiences with the mags mirrors mine.

Its easy – just drop by the recruiting office - or swing by BW, TC or Dyn

Back home I have as much trouble getting Mk262 - and frankly I’d much rather have it going to guys over here.

[Gunfixr]

After reading all of KevinBs posts, I just can’t see buying anything other than PMags. Especially when you factor in the costs. I’d have to be getting the USGI mags for about $3 apiece to make them worthwhile. With good followers already in them.
