double eagle m85 hi cap mag

[Sk8rSeth]

i have a kind of knock of mk36, the m85. its made by double eagle,my question is does anybody know of a hi cap magazine that will fit this weapon?
i can get extra 50rd mags for it for like $5 but i would really much rather have a hi cap.

URL for the 50rd mags,

and here is a pick of what the actual hole looks like for the mag



some of the hi caps i have looked at for the mk36 dont look like they would fit into this chamber? idk

and i thought about doing just that, but im on a budget, and a tight one at that, so i cant really afford to drop 20-40 bux for no reason uk?
