30 round mag > 10 round mag: how to?

[carsonwales]

How are the 10/30 10/20 mags modified?

Is there a stopper in the body like a shot gun plug? Or is there a cross rivet or bolt? What makes them 10 rounds?

From what I've seen it's just crimps or rivets in either side of the magazine so that the follower cannot pass that point in the magazine body. To put a crossbolt in the magazine would hinder its usefulness at all by blocking the spring compression.

[BossHogg]

Put extra followers under the baseplate. But make sure you permenatly affix baseplate afterwards.

What about a plug?

What about a plug?

I was hoping I could go out of state...buy the cheaper than dirt regular 30's and remove the floor plate and drop in a plug....

The damn 10/30's are a ridiculous 30 bucks a crack....

Further, if the ban was ever lifted or rescinded...they they can be readily converted back to normal mags...

Put extra followers under the baseplate.

Have you tried it?

It would seem you could get a 10 round mag spring...and then just block out the bottom under the spring with a plug or as you say...surpluses followers?

And that is why this would not be legal. There is a standard of permanancy for these magazines. Being able to convert them back to high capacity is not a goal you want to stay legal.

Well then here is the quandary...I own two or so dozen 30 round mags bought back in 1999...for use in my registered AW....also purchased back in 1999.

I have the one true registered AW....and now a few OLL builds. I don't want to pay the crazy price for a 10/30 mag.

I either want to get some cheap 30's out of state, modify them out of state OR modify a few of the 30's I already have.

How can I do this and STAY LEGAL?

I haven't tried that, but it sounds like an easy way to make a magazine that will jam every few rounds and never feed properly. As to a plug, like blkA4alb said, that is of very questionable legality, furthermore, unless the plug itself is very carefully created, it would also impede proper feeding by disrupting the spring movement.

As blkA4alb said the modification must be permanent.

You could always go the route of using the Monsterman grip and going featureless, allowing you to use all of your preban magazines, not modify them, and not purchase new magazines.

Sounds like a win-win to me.

I have 3 of them like this with no feeding prolems at all.

Ive talked to many LEO's about this. Many people think differently though. If it is a preban hicap mag that you owned before 2000 you may convert it to 10 rounds if the baseplate has to be distroyed to remove it making the mag not funtional. Then you may convert it back to hi-cap and put a new baseplate on it. You do not loose your preban mag by converting it to 10 rounds.

Most people that dont own preban mags dont want to hear this because they are mad or jealous

I never would've thought that'd work, but I haven't tried it, so I'll take your word for it. As to preban mags, I've got some, but I don't have enough that I'd care to convert any of them to 10 rounds.

I am going to do a MM build for sure...just for that reason.

I was wondering....could anyone post a pic of 10/30 mag close up so we can see how they are made?

If they are indeed tab punched or crimped to restrict the follower, then how in the world would you replace the follower should it become damaged?

It would seem if it was crimped or tab punched you would have to result to some pretty nasty sheet metal gymnastics to pull the follower?

How did you reinstall the baseplate such that it has to be destroyed to be removed?

Now we are getting somewhere?

[BossHogg]

I love the monsterman idea. I just hate you have to use the a2 butt stock... or do you?

JB Weld or tac weld it. You might have to file down your mag body afterwards but its no biggie
