Just discovered Magpul Magblocks- question about epoxying mags

[Sgt Raven]

I suppose it will work if I remove the block, but my magazine will fall apart soon enough because there will be nothing to retain the floor plate.

Have you ever taken a PMag apart? The floor plate fits snugly by itself. Then add the spring pressure of a loaded mag.

I say pin them so you can REBUILD them later as needed.

This. Why would anyone want to risk criminal prosecution for a $20 item?

This is Kalifornia, we risk criminal prosecution for just owning a gun legally.

IIRC, riflegear epoxies the magblock to the spring so they can still be disassembled.

Arrest, yes. Criminal prosecution? No.

Mags are a different story however.

Why don't you address my point on magazines instead of your red herring?

Arrest, yes. Criminal prosecution? No.

Prosecution: probably. Conviction, no.

Mags are a different story however.

Eh, seems like the magblocks replace a crucial part. That should be enough for the law. Though I think most of us realize, any of the DA's hoping to get an easy plea don't care since their main concern is the number of convictions.

I've often wondered if there is actually precedent for not having to epoxy/rivet/pin the magblocks: shotguns with rods or dowels in the tube magazine to limit legal capacity for hunting.

Decades before there was ever a question on how many rounds a semiauto centerfire rifle could legally hold, hunters have been limited to a capacity of 3 rounds in their shotguns for waterfowl. Most semiauto and pump action shotguns, though, can hold 5 shells (2 3/4", 1 in the chamber and 4 in the tube). So for hunting, they're sold with a plastic block in the end of the tube magazine. And in old guns, or for guys who've lost their block after a busy weekend of dove hunting (no limit on shell capacity) a section of wood dowel cut to fit works just fine.

The point is, game wardens have always accepted an installed block or dowel as an appropriate capacity limiter. Its not epoxied or riveted or pinned, its just sitting in there. It can easily be removed if you unscrew the tube cap. But its completely legal for waterfowl hunting shell capacity limits.

Wouldn't this be a valid basis for also limiting a rifle's magazine's capacity with a physical block? As has been mentioned before, owning 10+ round magazines isn't illegal, but assembling them is. So if anyone took out their Magblock and reassembled the magazine without it, that's the crime. But assembling & using it with a Magblock in, even without epoxy etc. follows the standard custom & practice done to limit capacity for hunting for generations.

Disclaimer: I'm not a lawyer, and I don't see the point of 10/20 or 10/30 round mags anyway. Why carry the extra weight and why let something you can't use stick out, get in the way, limit how close to the ground or a bench you can put your rifle? Any new mags I've needed, I just bought 10-rounders anyway...

permanence is in the PC for converting LCM to 10 I believe, and not for hunting with shotguns.

1.) Start with a 20 round PMAG parts kit and a 10 round limiter.
2.) Assemble magazine with the limiter substituted for the locking plate.
3.) You now have a magazine that *cannot* take more than 10 rounds (verifying is always a good step here).
4.) No matter what you attempt to do to that magazine, short of breaking it into a parts kit or breaking it internally by extreme downward force, it cannot accept more than 10 rounds. There is no "switch" or way to swap it to a higher capacity magazine without breaking it apart into a parts kit first.
5.) Take off the floorplate and limiter. You have now a parts kit.
6.) Put back on the floorplate sans limiter, you have now illegally created a non-reliable high-cap mag. It will jam, and be funky, but it is a high-cap.

If you want to feel extra safe, throw away the old locking plate, even though there isn't constructive possession.

Rivets can be easily punched out, pins won't stop you, epoxy breaks down. Short of putting a plastic rod in the magazine, heat molding it onto the floor plate, assembling the magazine and *heat molding the floor plate to the body to form one solid chunk of plastic*, you're just doing handwaving to make yourself feel more safe.

I'd feel very comfortable pointing out that the Prosecutor had to substitute parts *and disassemble* the mag from a legal configuration and *manufacture* into an illegal configuration to get more than 10 rounds in the mag.

I get Pmags for about 12.00, I figure I can just buy rebuild kits for out of state use. For in state use I block em then use super glue for the bottom plate. Its plastic and it works well.

[Seesm]

I have a few steel G.I. style re-build kits if anyone needs any.. All 30 round re-builds.

I think I have a cmmg or 3.. Some C-Products and the ones made by Colt but not with the Colt name. (made in the same town and I think begins with HT?)
I also have some Colts as well... Most are Mil-Spec and some have anti tilt followers...

Not sure what to ask for them. (They are just sitting in a box in bags apart and ready for mag fixing ) and I have all my mags rebuilt finally and really do not need these.

[goodlookin1]

I dont like how people say "just to be safe". What's safe? Time and materials are of no consequence....whether it takes you 1 minute or 30 years to undo, it's still not permanent.

There is NO SUCH THING as "permanent", thereby making it impossible to comply. The CA DOJ has REFUSED to define "permanent". They say "permanent is sufficiently understood by a reasonable person". Translation: You do what YOU feel is permanent and if/when you are caught, we'll see if your peers think what you did was "permanent". This law is so unconstitutionally vague, the stench of it reeks! Laws are not supposed to tell you what you cannot do: If they do not properly define what it means to be permanent, it is impossible to follow.

So in a nutshell, do the amount of "permanenting" to the magazine YOU think the jury members will also see as "permanent". But essentially, there IS NO GUARANTEE. Period.

Could one argue that:
The 30-round Magpul PMAG magazine (as well as any other magazine on the market) is designed to function properly if the magazine is not altered in such a way that would possibly make it dangerous and/or deadly by removing or altering existing parts. If parts were removed from the magazine, such as a base plate retention plate or any other part for that matter, it is no longer a complete, operable magazine per the manufacture's specification and could possibly result in injury. But, REPLACING existing parts with parts that are built to the manufacture's specifications, yet safely alter the magazine to only hold the legal limit of rounds should be completely legal. As you are within the limitations of the law with your magazine only holding 10 rounds, AND if you were to "alter" the magazine with said existing parts, it would be impossible to manufacture a complete high-capacity magazine without the parts that were replaced......... right?

I was just watching ShooterDude's video and it got me thinking

I shot a Pmag this weekend without the retention plate. Under recoil, the base plate would start drifting fwd around shot # 4-5.

Does taking a 10/20 or 10/30 appart leave one with what is legally defined as a parts kit or not?
