I have an AR, so I have parts. I have no GBBR, so I can't say for certain. But from what I have heard, WE ran into some trouble with this in the US, and so did G&P. From a design standpoint, it would be orders of magnitude easier to do this with a GBBR than to modify an AEG, which was my point.
I know the WA style receiver WILL not accept an ar-15 bolt carrier because it is shorter by a few mm
I'm not sure the firing group would work, then the bolt catch assembly is different. Magna hammer strike the lower portion of the bolt catch group which sends a pin forward to hit the gas release. Basically if you want to convert it into a firearms, you're gonna have to:
a) get a prime receiver (which is alot more expensive then AR-15 receiver in Canada (without import fee)
b) get the bolt catch group converted, this is gonna be hard since there's more cutouts in magna system towards the magazine area
c) some how get the firing group in
d) install ar-15 upper.
Honestly, if I really want to get an m4 cheap.... I'll just get the norinco CQ556 and mod it from there since it was originally full auto being factory
convert into semi (In the Firearms Act, a converted auto which is prohibited is a firearms originally capable of firing automatic convert into semi auto only by a third party, if it was original factory conversion then it is just a semi auto AFAIK)
