I’m guessing this is a typo, as I can’t find anything online about it, but anyone here know for sure?
A colleague posted it on facebook. My response was this:
That magazine doesn’t appear to have enough curvature to accommodate 7.62x54R. Guessing it’s a typo because I can’t find anything about a 7.62x54R Sig 716 anywhere.
Just thought I’d double check here.
Surely a typo. Magpul doesn’t make x54r mags of any sort.
Look at your number keypad and tell me what you think…
