I had bought a Type 99 with mum intact a couple yrs ago at a show for $75....it had been sporterized. (stock cut down only)
The bore looked good at the gunshow but upon closer viewing at home it was about 35%
Then I saw the cost of the ammo!
Wound up selling it to a guy that had the correct stock for it...sold it for $175....he was going to display it only....so we were both happy...
