If I remember correctly, it was an AR (maybe AK) pistol variant chambered in 7.62 x 39 that caused the old Norinco steel core ammo ban.
I think I remember Olympic Arms in it.
Correct, similar in configuration to the Romanian *Draco* AK shorty pistols that are both very popular an d on my own personal want list.
BTW, there was a rumble at the SHOT show where the new even shorter [8-inch barrel/ 18 inches overall] Draco was introduced, that there's soon to be a version in the 5,45 Soviet AK74 cartridge. Which means that the inexpensive supplies of the military steel-cored 5.45mm Soviet ammo now on the market will dry up very quickly, and further importation of the Russian and Bulgarian military 5.45 will be halted.
If you have a 5.45 AK-semi and like the (good stuff* ammo, get what you can NOW.
