Can You Identify This Mystery Magazine?

    A reader of the blog found this magazine in a box of junk being thrown out. Apparently it was found in the locker of an old timer who retired. The company he works for manufactures ordnance and fuzing for the military.

    The magazine is cast or extruded aluminium, definitely not stamped. The follower has an articulation that looks like it is designed to push the nose of a cartridge up.

    Can anyone identify what gun this magazine belongs to?

    I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!
