I want to buy some 30-round Magpul pmags to be used as 10-round mags for my Beowulf .50 rig.

Do you recommend any vendor who would ship them to CA ?

the only way you are going to get 10 rounders for beowulf is if they are clearly marked as "10-round magazines for a beowulf" as far as i know, there is only one company (alexander arms) that makes them, they stamp the floorplate of the magazine clearly indicating that it is for a beowulf.

I thought that a 30-round 5.56/.223 mag can only load to the max of 10 rounds of .50 Beowulf. Would that be considered meeting the 10-round limit in CA ?

What if someone swap the AA floor plate with a Magpul Ranger plate ? Would that make the mag illegal ?

The mag is designed to hold 30 rounds of 5.56 and that's what the state is going to look at.
Now, if you buy a magazine that's marked 50 Beowulf, it's obviously "designed"

for 50 Beowulf and the state won't question it's importation. ;)

Having said that, there's no law against using a magazine for another cartridge, such as using your 10rd 50 Beowulf mags to hold 30 rounds of 5.56...

The Pmags would be hard to use since in order to accept the Beowulf cartridge the feed lips have to be bended a certain way, so I don't think polymer bends just as easy as aluminum or stell lol. Best bet would be to just order the mags from www.impactsguns.com they have the mags in stock for a pretty decent price. Good luck!

Actually, the Al or steel lips need a little bent to avoid case scratching. Otherwise, there is no need to bend the lips. The polymer lips are actually just soft enough to hold and lead the cases without scratching them. There are several range reports showing no issue with pmags.

You're walking a fine line here...

I've been recommending going with the AA designed 10rd mags.

44mag.com sells rebuild kits of pmags, but you tell me if you're assembling them into beo or 5.56 mags?

I hear you.

Can the AA 10-rd load 30 rounds of 5.56 ?

I will say that the reliability of USGI 30rd mags have been pretty dismal vs just using the 7rd Alexander Arms Beowulf magazines, in both my friend's and my Beowulfs.

Most common issue is to get hung up on the last round.

The point is they don't ship them to CA even when the buyers want to comply to the law and use them strictly as a 10-rounder .50 beowulf.

Go for the AA mags... the little extra you may spend on the mags will save you a lot more in legal fees.

correct me if i'm wrong, but isn't it more ideal to fun the decdicated AA .50BEO follower in any mag rather then the standard 556 follower?

just buy a 30 round ummm "rebuild" kit...make sure never to put it together, and then buy the AA .50BEO followers and stick those and and create your magpul .50BEO 10 rounder. Then take a market or something and mark the mags "10rds x .50BEO only"

Remember, never assemble that "rebuild" kit into a complete mag :D

Magpul Pmags won't accept followers designed for USGI type mags.

5.56 and .50 Beowulf followers are the same.

I haven't had that problem, try polishing the feed lips. Mine work fine without polishing, but once polished they do not scratch the brass.

Here is what I do.....take a thick follower, like one for a 6.8 for a G.I. mag, or the magpul's are thick enough too. Grind the follower flat. It will now not hold 5.56. You can try all you want, but they just pop right back out! Bam! It will only large cals. I use this on my .458 socom. I have also done some for friends that have 50B. I had my mags engraved but its not necessary when it cant accept smaller calibers.


It works!

Also when you file that hump on the follower. It will stop any feeding issues. It lets the follower come up further then before.:)

It's a very good idea. I'll try that. If a 30-round mag can load nothing but .50B then we have a better explanation if LE wants to check on them.

Would it load any cartridge smaller than .50B ?

No go on 7.62x39, 6.8, and 5.56. Didn't try much else.

With the flatten follower, how many round of .458 or .50B were you able to load on to a 30-rd (5.6) mag ?

10 rounds.

Midway will - when they have them in stock, which as of late seems almost never.

Beowulf mags have lips that are slightly different than standard USGI mag lips. I don't recommend using anything except AA Beowulf mags, especially if your want your rifle to shoot reliably.

Here two theoretical question:

1) What are the legal implications in California if you buy AA 10 round .50 Beowulf Magazine but you do not have a .50 Beowulf upper? Let say I buy AA 10 round Mag to use with my featureless 5.56 AR rifle. Would I have a problem with "the law"?

2) Lets say I buy a .50 Beowulf upper but decide to use the AA 10 round Mag on my featureless 5.56 AR rifle. Would I have a problem with "the law"?

Not my experience. Regular USGI mags have worked just fine for me.

Then you didn't buy an AA 10 round .50 Beowulf Mag, you bought a 30 round 5.56mm magazine. Now technically purchase isn't a problem. However, did you manufacture a 5.56mm magazine when you inserted 5.56mm into it since it was designed to be something else?

If you import these mags, then you are guilty. If you buy AA parts kits online and then assemble them into .223 mags you are guilty.

I have 7 and 10 round mags I use for my .50 and they all say .223 on them. First, I keep .50 Beowulf ammo in them, so it is easy for me to say that they are for .50 Beowulf when they have .50 Beowulf in them. Second, they might have been .223 mags at one point in time, but all of the mags I own were bought before 2000. Third, even if they weren't bought before 2000, I have a large capacity magazine permit with my name on it and anything I possess is company samples. Fourth, it is not illegal for a regular citizen to purchase complete large capacity magazines from a person licensed pursuant to PC 12071.

I'll tell the coppers to pick my defense for me.

There's no law that says you can't have magazines for a weapon that you don't own yet. It's not constructive possession like with pistol uppers. Nor is there a law that says that using sub-caliber ammunition in a magazine designed for another is illegal either. You can have 10 round Beowulf assembled mags shipped to your door in CA too.

If you didnt mod any part of the mag, then feel free to use it as a 5.56 mag. Its not your fault 5.56 fits in the mag and also feeds properly. Putting a 5.56 round in it isnt manufacturing or modding anything.

There is no law against usage or posession.

Just dont mod anything and you will be good.

Can the AA 10-rd load 30 rounds of 5.56 ?

Yes, just loaded mine up (snap caps) no problem, and feeds properly.
