The 10/30 PMag - How To

[SixPointEight]

Thinking about pickup up some PMAG rebuilds to do this with. The 10/30s I bought work well, but I can't insert them on a closed bolt. I figure doing it this way should give me enough play to insert it on a closed bolt when full. Thanks for the info OP

Did this build and it worked flawlessly... except it's definitely 4-5/8" with the new p-mags I have. The 11th round will just barely depress the 10th but won't go in. As for the epoxy, you don't need near that much. Just roll the end in a small puddle place it and put the pin in. This beats buying the factory 10/30's for $30.

A toothpick can be used to apply the epoxy HOWEVER, I have found that dropping the mag on the floorplate or subjecting it to physical shock WILL break the bond. I believe this is due to Magpul using a Teflon additive in the PMAG polymer. I have since switched away from epoxy and now insert a stainless steel roll pin in the baseplate.

I have to admit I haven't read all 191 posts in this thread but after doing a search I still can't find any information about how to permanently seal the floor plates on these pmags? What is the preffered method you guys are using, epoxy, JB Weld, rivets etc.....

My preferred method is a roll pin in the baseplate. It's inconspicuous but robust.

Be careful with this. The polymer that PMAGs are made of WILL flex about 1-2mm and it only takes 2.5mm to slip the next round in. The ability to load on a closed bolt can result in your 10rd mag being able to accept an 11th (will not feed but the law is how many can it accept, not how many can it feed).

I know this is an old thread, im sort of skimmed through it for the answer to my question.

Why do i have to seal the whole mag closed? If i epoxy a rod under the follower, the mag at that point is a 10 round permanent magazine. Now the argument is that i can dismantle the magazine and add in a new follower without the rod. At this point, the magazine has been dismantled and is now a rebuild kit which is legal to own. Putting in a new follower and assembling a 30 round magazine from that point would be a crime. But prior to it being dismantled, it was legal. Does anyone get what I'm trying to say?

I agree with you on this. I don't see the point epoxying the end plate.

I used this method it works great I also used the epoxy to glue the footplate to the mag body the epoxy I got says it has 1500 pounds strength sounded like permanent to me

Great Video . I will be doing this to a couple of my AK mags today.

OK I tried this with my AK mags and I got all the pcs. made but when I went to go assemble the mag the dowel was getting hung up in the spring or mag wall and not allowing me to load any ammo. I`m thinking that with the ak mag being much more curved than other mags its getting caught on the wall of the mag. Any suggestions?

Great write up! However I like the idea of the rivet cause like they say, "If s,hit ever hits the fan" its easy to pull it out. 8)

On my AK 10/30s I put the follower stop on the bottom plate and not the follower itself. Works perfect as the dowel does not move.
