22-250 model 11 extra capacity magazine

Hey guys.
Lim in Canada which limits my options because no retailer will ship over the border. So does anyone know a supplier for an extended capacity magazine.
Or is there some kind of conversion that will allow it to accept more easily acquired magazines,like the cheaper plastic AR mags or something.
I'm sure I saw on YouTube a guy had a model 11 that had a longer,almost looked like a 30 round,magazine.
If there is a conversion kit that makes ar-15 mags work or longer aftermarket magazines,that are in Canada already and don't need to cross the border and you could point me in the right direction that would be absolutely fantastic.


Thanks guys

If it is a centerfeed you should be able to use the bottom part of the regular 10 round mag on your 22-250. I am waiting on a 22-250 AI barrel and am planning on using these. Just haven't done it yet to tell you if it works or not.

Try Aztech Armory

K. So I buy this mag and canibalize the one that came with the rifle then and cobble them together?
I'm cool with the idea,just wondering if that's what your saying?
