Buy recommendations Henry supreme mag?

Post image

I just put a down payment on a Henry supreme 5.56 at my local gun store. I was under the impression that these magazines have to be pinned to 5 but my gun store employee said it's a 10 round limit which makes no sense to me. Is there some sort of loophole that he knows about and I don't? Or was he bullshitting / mistaken? Pic for attention.

​

Regardless, what is the best magazine option for these things in Canada? All I'm going to be using it for is target shooting for now.

​

Thanks In advance!

Canuck arms I believe made a bolt action rifle that takes proprietary mags very similar in footprint to AR mags. They have an extra vertical rib that prevents them from inserting into an AR magwell. I wish I could remember the rifle name.

You can modify the rifle to accept the magazines and it's perfectly legal, they sell them up to 20 rounds I believe. You will have to Dremel out part of the steel on the magwell but I believe there's been posts of people doing it successfully.

Do NOT modify the magazine to fit the rifle, you'll be getting into hot water about redesigning it and it could be considered now designed as an AR mag.

You’re likely thinking of black creek labs, they make a modified ar mag that holds 20 rounds that only functions in their MRX bolt actions- this mag has the extra rib you describe.
