I have a semi-auto MK 760 incoming and I was browsing for options for magazines. While both BWE and Scott Andrey Machine offer magazines, they're priced pretty well above the cost of Suomi mags, which I realize have to be fitted.
I was looking at Numrich's website and they have a section for MK 760 magazines, though the photo they have is identical to their Suomi magazines.
Should I just go for the cheaper option and get standard Suomi mags and be prepared to do a bit of filing for each one or go for the mags labeled as for the MK 760 on Numrich?
