PINNED MAGAZINES

[mxadam579]

Well i been reading a lot on the 10/30 mags pinned. Would this be legal if i had a 30rd mag and rivited it to only accept 10rds then melt the floor plate to the body since there plastic. would this be considered legal thanks

That would be fine, but I think melting it would be beyond the call of duty. Even factory 'factory' 10/30 magazines are only riveted, not melted.

Pinning the magazine is not necessary, neither is melting the floor plate. As long as your modification is of a design which can not be defeated while the magazine is complete, you are ok. People shy away from just a rivet since with enough force you can break that rivet off allowing the follower to go farther down.

Magazines from Glock, S&W, Armalite, Bushmaster do not have pinned or epoxied floor plates even when they use longer magazine bodies. They simply make sure the follower can not push past the limiter.

Getting a true limiter is better then making one of your own.



The pinning of the floorplate was born out of a misunderstanding of the law and from a distrust in the people (police) who would be enforcing the law. Yes there are a few Officers who still want to see welds of steel, epoxy, rivets, pins and glue on homemade magazines, yet don't give a Factory Glock magazine a second glance...

i was actually gonna put rivets on both sides

be careful. rivets on both sides can interfere with the magazines insertion... I did that once with failed results...can't remember why, but I know it had something to do with the rivet hitting the magazine well.

What if, with some force, an 11th round could be forced into a 10/30 mag with just the limiter? I doubt it would function properly and would be difficult to remove, but would it be prosecutable?

In a 10/3 this would cause problems. When I first set up my blockers, I made them just small enough to except the 10th round. The won't take more than that.

Why not place a rivet here:

This would be as permanent as the side of the mag...

Its a toss up.
In the purest interpretation of the law, the magazine is a LCM which was illegally manufactured post 1/1/2000. If inserted into a magazine with a magazine release lock, the firearm becomes an AW, even if it can't properly feed.
On the other hand, in reality, the magazine is defective and the firearm would too be defective and not a true AW. Its just like if your disconnector spring breaks (AR15), your firearm will double or triple burst making it a defined machine gun post 1986 in violation of NFA. Its not a major issue unless you leave it that way without fixing it.

I can break and/or cause any 10rd magazine to hold 11. Its easy. The debate then hinges on who what where when and how... not just if it holds more than 10.

There are two saviors in the law.
1) LCM Possession isn't illegal on the face of it, meaning the government needs more info on who what where and when before a proper arrest. As long as you don't provide that information...
2) A 11+ rd magazine can be sitting right next to a firearm (with a magazine release lock) and the firearm is not an AW. Who is to say when that 10rd magazine gains the capacity to hold 11? It could be the first time the Officer forces that 11th round into it....and if the magazine is out of the firearm at that time, its still not an AW until the government can prove the magazine held 11 while it was in the gun. No one manufactures an 11rd magazine for the AR15. So its obviously a defective magazine. The debate then again turns to who what where and when..not if the magazine holds more than 10.

My advise is...
1) Check your home built 10rd magazines several times for capacity. Have 11 rds in front of you. If you have 1 left over...as your tool, you are good. Check your magazines before and after each session.
2) Use commercial limiting devices. Its much harder for the government to make a case against you, when its not you who manufactured and/or designed the limiting device. I will toss this in here and many call me a hypocrite for this. I manufactured several 10rd magazine from 30rd magazines. I then came to the conclusion the risk is too great so I destroyed them and bought factory made (small body) normal 10rd magazines. I advised against the so-called 10/20 and 10/30 magazines. I recently bought a 10rd magpul magazine that has a 20rd body... I will never call any of my magazines 10/XX... all my magazines are 10rd magazines period, end of story..the size of the body means nothing...they are all 10rd magazines. I also own 30rd magazines which sit in a box in my garage labeled...30rd magazines.

You are missing the point. He is placing the rivet on the spine of the magazine to stop the Follower from moving farther down thus stopping it from loading more than 10. He is not using the rivet to stop the floor plate from sliding off.

As I have said, there is no reason for that. It factually legal to have the ability to take your magazines apart... its even legal to have the ability to manufacture a LCM post 1/1/2000...its just illegal to do so.

The law states a LCM is not one that was permanently altered to hold 10 or less.

Permanently altered is defined as what a normal reasonable person believe it to mean. The AG and most normal people understand, acknowledge and know you can never physically permanently alter anything so it doesn't mean "can never have the ability". It means "can not have the ability". Permanently Altered is a function of time, not the physical ability.

What then becomes illegal and illegal manufacturing is if I had you a 10rd magazine and you find it holds 11. You then get the brilliant idea that 11 = 30 in the eyes of the law and turn that defective 10rd magazine into a 30rd LCM...you have manufactured a LCM post 1/1/2000 in violation of the law by using a 10rd magazine that held 11. The 11rd capacity didn't make the magazine a LCM, even though the law defines a LCM as one holding more than 10.

... yeah I know

Why oh why do people have to over think EVERYTHING.

OP - go buy a mag block (they're like $6). EOS
