10rd+ AR mags

So would a .50Beowulf XCR pistol with supporting purpose built magazine actually convince you to show Robarms some love? At least temporarily? :p

I already own a half dozen XCR-L pistol magazines in 7.62x39 for my 6.8SPC. That's probably all the love for the moment. :D

AR15 pistols aready exist. All you have to do is throw a .50 Beowulf upper on an AR15 pistol and presto you can put 10 rd proprietary mags for that calibre into the firearm. The ONLY catch is that the magazine has to be build and labelled as being a pistol magazine. I just confirmed this with an RCMP technician an hour ago.

That's a fairly substantial catch, as both the metal and polymer magazines for the .50 Beowulf are currently sold as rifle magazines. That's good if the RCMP confirmed it, but I'd be inclined to have something in writing before venturing out with one of these...
 
Hi all,

Straight to the point, we all want 30 rounds in the AR15 magazinse.
18 rounds of 5.56 fits in .50 Beowulf 5/10 AR15 Magazines.

Is it possible for us to come up with a pistol version AR15 chambered in .50 Beowulf, so that it can legally have 10/10 rounders, which conveniently fits 36 Rounds of 5.56?

Or maybe the .50 Beowulf chambered XCR, which conveniently has pistol versions of their rifles? This way we can do the 10 Round LAR mag again, but appearance-wise more like the standard AR15 Magazine.

As for the geometry, It appears that .50 Beowulf functions fine in Pmags, so it shouldn't be a problem to use standard 5.56 AR15 magazine dimensions for the magazine. Most importantly, have the magazine marked "10 Rounds XCR .50 Beowulf"

Is this do-able?

Holy crap, that is a big bullet.

would it be better if we all re registered our ar's as .50 pistols? then it would be more than common... just saying...

According to the RCMP that's irrelevant. The tech just kept repeating that if a magazine is designed and manufactured to be a pistol magazine and is clearly marked for its intended calibre, then it doesn't matter how many rounds of a different calibre fit into that magazine. So I asked what about the case with AR15s where you can swap an upper for one in a different calibre? The tech replied that if you had a magazine intended for that different calibre and it was manufactured as a "pistol" mag, then you can put 10 rounds in it of the new calibre, regardless of the calibre of the lower.

lets get them pistol mags going then....

exactly, all we need is FRT #'s for 50 beowulf pistols, (the # of actual beowulf pistols is irrelavent, it is commonly available, as opposed to commonly owned)

and mags that explicitly are manufactured for BEOwulf pistols, and NOT advertised as fitting rifles, then they follow the exact same rules as the LAR-10 mags. If the manufacturer advertises them as fitting rifles too, its a no go just like with those bolt action stanag magazines

Just FYI, there's no FRT for a .50 Beowulf pistol - the two models listed specifically state "rifle". In order for the pistol magazine thing to fly, you're going to need a .50 Beowulf pistol registered as a "handgun". I imagine the RCMP lab may want a physical sample, too - and then they'll probably also want to see the pistol-specific magazine. This could be a rather involved and drawn-out process...
 
yeah... so we need a registered .50 beowulf pistol, and mags marketed and marked as pistol only, then done and done...

easiest way is to take a RRA pistol AR, that is already registered as a pistol, put a .50 upper on it, and get the new caliber registered, so it is then a .50 beo wulf AR pistol.

hard part will be getting a manufacturer to actually make mag specifically for 50 beo pistols
 
I don't know about you EasySauce, but I'm quite content for now (well I'm #249 on the pre-order list so we'll see how "now" that will be) with the idea of cramming 18 rounds of .223 in my .50 beowulf mags.

10 round pistol mag will just be the cat's a$$ for sure.

same here, have 3 on pre order as well,
 
Doesn't NEA makes mags. Couldn't somebody try and convince them to make a Beowulf pistol mag*? Or at least mark some mags as such for the RCMP and general sales.

*mags meant to hold 10.9 rounds of .50 Beowulf
 
beowulf is a proprietary thing, have to get permission from them to make the mags, thats the hardest part is getting the permission and the licensing $ to put .50 beowulf on the mag, doable, but would take significant investment, and a real business proposal, but once done would rake in tonnes of $ for whoever did it, beside being more ammo for changing the law.

getting the FRT is the easy part

My understanding of how the law was explained to me today is that you wouldn't need a 50 Beowulf pistol to be registered with a FRT. When I asked if you could make a wildcat calibre upper and pop it onto a AR15 pistol lower, the RCMP said that if the wildcat magazine is manufactured and marked as a pistol mag, then it can hold 10 rounds.

Look, below is the letter Questar got that opened the door to all this pistol magazine business. No where in the letter does it state that the LAR15 pistol must be in the calibre .223/5.56mm. The only place it says that is on the magazine. Ergo, who is to say that an upper chambered in a different calibre would require registering? The only snag in this letter is that the RCMP have stated that the C-products LAR15 design specifically has been accepted. However, that said, how many other calibres are AR15 pistols mags in now? Plenty. Are all these designs being submitted to and accepted one by one my the RCMP? I'd like to know. Perhaps some of the other dealers or importers can chime in here.
