Is it legal to have a riveted 10/30 blocked mag with mag extension?

[NatetheGr8]

The title says it all guys. Got a buddy who may be moving here if they get the house. He's from a free state and he's got a ton of mags; I'm sure he's got more since the last time I visited him not to long ago. He competes mostly in his gun club range. Thus the reason he has mag extensions. So with all that said if he ends up coming here could he just rivet the mags that have the mag extensions to save him time and the hassle? Mag extensions are expensive which is why he rather not just ditch them. Though with some laws and the way they're written it's hard to find a clear answer to this specific situation. What do you think?

Over 10 round magazines must be "permanently" altered to only hold 10 rounds maximum. The new regs refer to riveting and/or epoxying the magazines.
But, does not specify that that is the only way to make magazines permanent.

As usual, DOJ is leaving it open for a District Attorney to make the decision on what is permanent.

Although, I believe if you block and epoxy or weld magazines in a way that trying to disassemble them would destroy the magazine, it would be acceptable.

Thanks! Anyone else who can help? I'm assuming it may be ok, it's riveted at the body of the mag not the floorplate. Sorry I should specified that was the intent. So with the rivet on the body blocking the follower from going any further; you may have anytype of mag extension/ floor plate one would like.

If I'm understanding you correctly, couldn't the rivet be drilled out so it no longer blocks the follower. If so, that would not be permanently altered and would not satisfy the requirements of the law.

Anything that can be done, can be undone. So anything can be "permanently altered" until it is unaltered. Even welding.

Epoxy is easiest of all. Just dump the mag in a can of "Acetone, MEK or Styrene" and wait a day. POOF, epoxy gone.

If that's the case all the 10/30s and etc are all illegal. Even the one I get from gun shop and the one that come with my rifles when I buy it from the shops.

Exactly!

Anyone else got an opinion?

Well nothing is really permanent so it's open to interpretation.

I could make a brand new 10+ magazine from magic and thus is an existential question.

Anyone got answer to the original post?

We have a State full of District Attorneys with their own answer, most different from their counterparts. They are free to make their own determinations, and in so doing render the law unconstitutionally vague.
To the law abiding simply writing "10 rnds max" on your mags is a "permanent restriction".

As long as they are "permanently altered" into 10 round magazines, they will be CA legal. [11 CCR 5491(b)(1)]

11 CCR 5491
(b) Prior to July 1, 2017, an individual may dispose of a large capacity magazine by permanently altering the magazine's feeding device so that it reduces the capacity to 10 rounds or less.
(1) A large capacity magazine that is a box type can have it's capacity permanently reduced by using both of the following methods:
(A) Inserting a rigid magazine capacity reduction device, also known as a magazine block, into the magazine body and then affixing the floor plate of the magazine to the body of the magazine with permanent epoxy. Metal magazines with metal floor plates have the option of being either welded closed or permanently epoxied closed once the magazine block(s) have been inserted. Due to magazine manufacturing variations (such as drum magazines or tubular magazines) it my be necessary to insert multiple magazine blocks in order to reduce the capacity to 10 rounds; and
(B) Once the capacity of the magazine has been reduced by inserting a rigid magazine block into the magazine, it shall be riveted in place through either the floor plate or side wall of the magazine body.

Thanks Quiet! That's what I was waiting for. So a rivet to the body of the magazine that blocks the magazine follower to the point where no more than 10rds can be inserted; with a magazine extension, floorplate, ranger plate and etc. Is legal in CA? Correct? Blocking a magazine to 10rds can be achieved with many methods as long as it's achieved is what I'm understanding.

Mag extenstions are legal as long as the mag only holds 10 rounds and is not able to be unblocked.

Internal mag block
Epoxy glue
Pin

That's what the DOJ rules say

Tell him to leave his mags with a buddy in a free state and just buy 10 round mags
