AR-15 .450 bushmaster?

Contact your favorite dealer and have them contact Gravel for the parts.

There are 16" and 20" uppers available along with mags or complete rifles.

I'm going to be taking apart one to use in/on my Maccabee Defence.
 
Look into the current magazine capacity crap that is going on with the 50 Beowulf which also applies to the 450 Bushmaster as well as the 458 Socom cartridges. They're all great cartridges if you feel the need to pay a lot of money to make bigger holes in paper (in the case of the AR platform) but with a 2 round magazine limit you may want to rethink your plans. It would make more sense to me if you were putting together a non restricted but even then a 2 round magazine limit is a lot less fun.

I know it's just a bulletin the RCMP have put out and that it isn't actually law yet but you can be sure that means they are working hard to make it written law and you also may not want to be one of the guys who gets caught with an AR magazine that can hold more than five rounds of 223.
 
So you're saying if I build my Macabee in .450 for moose hunting, some how I have to pin the mag to 2 rounds of .450?!?!

Does not apply to 450 bushmaster, the mags are their own design that can not even hold one round of 223/556
 
Note the lips do not retain the 223/556 round

note the internal limiters that prevent any round from "double stacking"

Here is the Remington 30 AR magazine, equally as impossible for it to hold even one round of 223/556 but an entirely different design again.

It is unfortunate that the designers of the 50 beowulf and 458 Socom chose to use a regular 223/556 magazine to feed their rounds, in the USA it is not an issue, but with our cartridge control regulations in canada, it is.
 
Where ya guys getting the .450 BM mags at? That was my plan for the Maccabee set I have on order. Make a nice bush thumper.

Lol I disagree. Guys running Beowulf mags in their .223 ARs got WAY more enjoyment out of them than the three people that actually bought or built .50 Beowulf uppers. :)

I guess, If you are talking about guys who risk a prohibited device charge for an over capacity 223/556 magazine

Note I said got, past tense. But yes, those are the guys I am referring to. 15 rounds of semi auto goodness :D

It was glorious while it lasted. Potentially still is, for potentially many of those guys.

If you can find 450BM magazines and your plan wasn't to just use the common and easy to find Beowulf magazine then you might be ok.
The bulletin says any magazine that it derived from a standard 223 STANAG magazine. I really have no idea how far they would take it but since they all look the same until you actually look at the follower and feed lips I can see
I'm not really sure what would happen if you were stopped with one, if the officer felt like it he could charge you with possession of a prohibited device and then let the courts sort it out.

The letter the RCMP sent out to retailers like Armtac and others specifically named 50 beowulf and 458 Socom. The reason being is they still hold and feed the 223/556 rounds the magazine was originally designed for.

I have been stopped out hunting, no issue so far, don't seem interested when they find out it is not the other "B"

The legal comments in the FRT for the capacity regulation are also only on 50 beowulf and 458 Socom entries
