I have a few boxes of counterfeit lake city 30 carbine ammo. All brace is dated 52. If you are unfamiliar with this stuff look it up. Foolishly bought it at the Baltimore arms expo for $20 a box. Ammo comes in a gray box rubber stamped LC 7.62MM, It has an interesting story if you do your research. AMMO IS CORROSIVE. Buyer beware. Looking to sell it for what I paid for it. $20 per box of 50.
