Law Question Would this be a permanent modification to limit your magazine?

[Fleaz]

i was messing around with ideas for blocking magazine with the 3d printer, i came up with this. basically a pin you melt down over the base plate. This will affix the base plate to the floor plate/block. the pin is attached to the floor plate making it impossible to remove without destroying the now melted/mushroomed pin. you would have to replace the pin in order to reaffix the magazine. this would allow you to service your blocked magazine without needing to purchase a new base plate and floor plate every time, just replace the pin. would this be legal? mag used in photo is a 10rd mag blocked to 9 rounds with new insert lol.

I don’t think anyone really knows what constitutes a permanently blocked magazine. The DOJ has declined to offer any guidance on this, and the originally proposed regulations, which required both permanent epoxy and a rivet, were never approved. I’m not aware of anyone actually being prosecuted for possessing insufficiently blocked magazines, so I don’t know of any case law on the matter, either.

Typically, in the rare instances where the capacity of magazines owned by otherwise law-abiding citizens comes under scrutiny, magazine owners inform the authorities that they obtained the magazines prior to the original ban or during Freedom Week, and the burden then falls on the government to prove beyond a reasonable doubt that they didn’t. Savvy DAs understand the difficulty of overcoming that burden of proof, and act accordingly, as the DA did with Pheng Yang about a year after Freedom Week:

As mentioned above it doesn't really seem like anyone knows exactly what they mean regarding permanently blocked mags.

I see folks simply using rivets on the mag body itself, a block only, a block with a rivet on the base, block with epoxy on the base.

Just look at what we recently saw regarding barrels having a pinned & welded muzzle device to reach the 16" minimum. That goes to show how far the gubt will go when they want to push an agenda.

I'd be more worried about a mag potentially taking that 11 round if forced than the method of blocking.

I go to ca often for work and took the 15 round mag that came with my Canik mc9 and used a mag block to limit it to 10 rounds and used some epoxy.

Can’t ccw it in ca anyways and prefer the flush 12 round mag at home. IMO it can come down to if an officer sees you attempted to comply or a case where you are up to no good activity in the wrong neighborhood.
