Was just looking thru the magpul catalog and noticed 5 and 10 rd magazine blockers for their 20 rd pmags. Since I've never read about them here am I correct in assuming that they won't cut it for the 5 rd law? I am assuming that the fact that they can be removed prevents them from being legal. Is that the case?
 
I've had plenty of internally blocked AR15 magazines. Bought them like that and sold them like that. I suppose it all depends on how you define "permanent". It's such a sloppy word for what should be a clear cut law. I wouldn't even be surprised if at some time in the future the liberals sic their dogs on us for rivetted mags as being non-permanent.
 
I've had some people try to convince me otherwise. From what I understand, you need a "tool" to remove any round limiter for it to be legal. I doubt the magpul blockers are tool-y enough
 
I believe the rule of the thumb to be legal is that removing the blocking mechanism requires destroying it. Drilling out rivets, for example. Being removed by a tool is not good enough, as you can just pop it in and out. That's why a simple screw isn't legal.
 
I have a couple that are 'blocked' but they also have two roll pins installed through the body/floor plate that prevent you from sliding the floor plate off.

They are pretty small diameter pins too. It would be a righteous pain in the nether bits to remove them.
 
Magpul markets it as a tool less, non-permanent way to limit mags for places that have limits on hunting capacity. They even state that they're not legal in jurisdictions that prohibit 20 rd mags so I seriously doubt that they'll fly up here. Having said that, make it permanent and you should be good to go. You could epoxy the base plate in place or rivet the base plate so that it can no longer be removed. Kind of a moot point since they'll likely be riveted already by whoever imports them, and this would only increase the price of the mag. Rooster33 was selling a similar conversion a few years back.

No, they won't cut it - simply because they're removable. While you could probably epoxy them in-place, that would preclude ease-of-maintenance down the road. Since it limits it to exactly 5 rounds, you wouldn't be able to load on a closed bolt, either - so now you're down to 4 rounds. :(

Honestly, you're further ahead with the standard flush-riveted 5.5-round PMAGs. Then you can also use the ranger plates.

What about almost every single factory Swiss Arms magazine with a set screw in the spine? I've had dozens of them over the years...

i saw a device the other day that covers the mag release of semi rifles. it requires you to use a tool to change your mags. it is designed to slow down a mag change. i think it may also accept a bullet tip to activate it. forgot its name though. designed for the california market.

Hmmm, I've seen reputable retailers with Beta C mags with a phillips screw in the back. I thought it seemed slightly odd then too though.

I've also seen these and was very surprised when I saw it. In my opinion, I don't think they would pass muster. Maybe the RCMP lab decided that to remove it you have to take the whole magazine apart, it's not a quick and easy task, so then it's alright. I really don't know. It's probably going to get someone in trouble.

If you can put a wrench on them and screw them out, they aren't up to snuff and you have a pile of prohibited magazines.

All the ones I've seen have a set screw that is then epoxied over to glue it in place and to fill in the hex socket. To remove it, you'd have to destroy the epoxy, thus destroying the pinning mechanism, therefor legal.

Magpul 5 Round limiter installed, some of the 20 round Pmags already have the hole for the pop rivet in the floor plate.
Unfortunatly you can't use Ranger Floor plates with the rivet.

I think the nick name is a "bullet button". Proper name of Raddlock?
