Newbish question, I know.

There was, at one point, a very good picture in this forum showing exactly where to place a pop rivet to make a 10/30 Pmag.

I cannot, for the life of me, find this picture again. Anyone have it handy?

I fully understand the perceived problems in blocking a standard-capacity magazine using thisspecific method. I'm working on a modified-new method and this picture might be helpful in preventing me from drilling a hole and placing a rivet in the wrong spot.

Thanks in advance.

Not quite. Maybe I should have been more specific. Looking for exactly where on the front/back of the magazine the rivet needs to be placed to stop movement of the follower.

Exactly like this...http://www.calguns.net/calgunforum/showthread.php?t=147553...except for a Pmag.

There was a great pic showing exactly where to put the rivet, and now I can't find it.

I've done this. With the baseplate off measure 3-15/16" from the bottom on the backside and drill a 3/16 hole and put in a 3/16 5mm rivet. You'll have a perfect 10 round magazine.

That's good info right there. Might do the trick, though I would still would like to see the pic.

Here's a couple pictures of my pmag for ref. Notice theres an extra hole at the top. That's because on the older pmags I got dated from mid last year, that's where I would rivet the body to only hold 10. Something changed with my new mags dated 01/09. The follower is a bit longer so I had to drill another hole.

Wow! Thanks Arteeel...that's exactly what I was looking for.

I'm guessing that these mags are the newer 'Revision M' mags that started shipping earlier this year (the dust cover snaps onto the bottom of these)...hence your initial drilling of the hole in the wrong spot.

Thanks again.

Thanks again.

The ones pictured are not "M" revision. You can tell by the more pronounced ribbing, recessed area for the window and the base plate is not notched so the dust cover wouldn't snap to it.

No they aren't the M version. But magpul did make some changes from the ones I had last year. My older ones would not drop free from my lower so I had to shave the 2 tabs on the back and I'm guessing they changed up the follower.

Yup, as long as it's done right. :)

I always check them to make sure they only hold ten rounds. I've done so many of these it's crazy. I got them all from a really cool guy on here too! ;)

I'll post a full tutorial sometime. I have all the pics.

Out of curiosity, what's the rivet point for a 10/20rd?

black touch up paint on the rivet even :eek: Now that's attention to detail! VERY nice :)

You cannot do it with the 20 round followers becuse the rivet would need to go inside the mag well on your lower. If you replaced them with the 30 round followers you could do it. I usually just pin the 20s internally with a plastic rod.

You can rivet the side, which doesn't affect the insertion - it's on the thin part of the mag.

A riveted baseplate and an internal insert is probably a better choice for the 20s and is what I've done, as well.

By the way, nice pics.

Based on the ribbing, spring plate, baseplate, and lack of window recess, yes.

Yes, those are. I've done the old style as well and I used the same measurement.

Ya, but what length need the rivets be?? too long will interfere with the spring right? what length have you guys successfully used?

1/8-1/4" grip range is what you're looking for.

gotcha, but now, how does the rivet tool work? im doing some practice runs on other things, and there is a huge nail sticking out the back once its done, am i doing it wrong? or does this need to be cut off?

You need to get a pop rivet tool. The too grabs the pin and pulls it untill the shank expands and the pin will snap or "pop".

I've always wondered why it seems so hard to make a 10 round mag. Load 10 rounds, drop in the follower, mark, drill, and rivet.

why rivet when you can get set screws which look better?

So does a set screw meet the definition of permanantley altered?? I know a rivet does, but not sure that a set screw does.

Thoughts?

Make another hole so it will hold less than 10 rds rather than just being a kit or JB paste the wrong hole and make a new one.
