Midwest industries m-lok shell holder - Midwest Industries Universal Shell M-LOK Holder

I bought a couple of these to complement the Midwest Industries straight stock that I purchased for my Marlin 1895 45/70. They seem to grip the fat 45/70 shells very well. I haven't used the rifle out in the field yet, but would imagine the shells would remain pretty secure with the movement and bumps associated with moving around in the field.
