need help-Dimensions of 243-308 detachable box magazines

[mncarpenter]

Is there anyone with M14 mags, FN FNAR mags or similar mags that can get accurate dimensions for me? I need length(fore/aft) and width(side to side).
Calibers needed are the derivatives of 308- if I've been confusing re: the dimensions I need see attached pic- I've scoured the 'net for dimension and have dimensions for Ar-10 mags, FAL mags.
Other possibles are Remington 750/742,BAR Stalker, BAR MK2,any bolt rifles w/ detachable box mags, etc. In other words any available mags..
-Thank you in advance for any help
