Lets see, sks shotgun news $99. box of shells 7.62 x 39 $3. This caliber is not going extinct, The government does not have the money to buy back all of the surplus.
And lets say that they did a forced recall, NOPE to many small town farmers and ranchers use this round to shoot varmints. And needless to say local "militia".
Don't know what the greater fear would be {for the government} groups of guys with high powered guns. or billy bob sitting 400yd away drinking a 12 pack like he was back home shooting squirrels. and your the squirrel.
That sounds like the revolutionary war?
