Making a 10/20 PMag legal

[10fcp]

I just bought 2 20rd PMags parts kits. I have also bought the 10 round Mag Blocks. To be legal does the floor plate need to be permanentaly attached?

Yes. Either apoxy or rivet it so it is considered permanent.

I don't believe that's the case.

You epoxy the mag block to the SPRING. There is now no way to assemble the magazine, spring, body and floorplate into a configuration that can accept more than 10 rounds. Once you assemble the magazine, it is a ten round magazine. If you disassemble the magazine, it is now no longer a magazine... it is a rebuild parts kit.

If you epoxy the floorplate, how on earth are you going to disassemble the magazine for rebuilding or even simple cleaning? That defies common sense.

Once you assemble the magazine (with 10 round limiter), it is a ten round magazine. If you disassemble the magazine, it is now no longer a magazine... it is a rebuild parts kit.

This.

^^ anything else is FUD.

If you have to take it apart to make it bigger, its permanent. No glue or rivets required.

While I agree with you in principle, and you may very well have a point that would prevail in court - there is no jurisprudence determining what constitutes "permanent". A law officer could - perhaps rightfully - conclude that if he, without any special tools or breaking/damaging part of your magazine, can re-configure it to a high-capacity configuration using just the parts you yourself assembled... he has enough of a case to at least hold you pending review of the facts... in other words, he may feel he has justification for an arrest.

It is widely believed that simply epoxying the spring to the mag block is "permanent" in the sense that now something has to be broken or altered with a tool to make that magazine contain more than ten rounds. That is NOT necessarily the case if the spring is simply slipped over the mag block, such that anybody could remove it from an essential part of the magazine.

There is no guidance from DOJ on this subject, so it is a subject with plenty of room for conjecture.

Note: the configuration outlined above (spring epoxied to the mag block) renders that magazine "permanently" converted to ten rounds in a conventional sense, barring the use of any tools or replacement parts. There is nothing that I can perceive in law preventing a person from owning in their home an infinite number of partial rebuild kits (i.e. springs). If one travels out of state, there's no reason why these springs couldn't be temporarily assembled into the magazines for standard capacity. I don't believe it's very plausible that a "constructive possession" case could be made simply for having a rebuild kit on hand unless there is evidence of intent to break the law.

It's a grey area, and there is no shortage of opinions on the matter. Epoxied mag block is what makes me feel "permanent" enough to sleep well at night and safe when traveling to/from the range, and is what is recommended by the mag block manufacturer. That's good enough for this guy.
