It is very clear... Have you ever read it?
The maximum permitted capacity of a magazine is determined by the kind of firearm it is designed or manufactured for use in and not the kind of firearm it might actually be used in. As a consequence, the maximum permitted capacity remains the same regardless of which firearm it might be used in.
The same capacity of what ? The same caliber or another one ? So much place to interpretation ...
With the Lar-15 mag it is clear. We are only using 10 rounds of .223 for what the mag have been manufactured for.
They also gave in exemple the Marlin model 45 but again it is a pistol mag that is loaded at is maximum capacity and in the same caliber.
On the section 5 they talk about the switch caliber and they use a good exemple with the HK P7 but it is clearly write " 5. Magazines for semiautomatic handguns which contain more than ten (10) rounds of a different calibre " They are not talking about semi-automatic rifle.
It is just lacking of precision.
Call them and see by yourself what they have to say.
Why they are not able to say YES or NO ? It is a real problem because they are supposed to be the authority on that matter.
I am not saying you can't do it but it is what i call a grey Zone ...
