Jinsen Arsenal Type 99 7.7 Japanese caliber rifle. Last ditch rifle made at Jinsen Arsenal in Korea. Ground mum. I saw one of these advertised locally for $250. Is this the same as your arisaka 99 Hamp?
rifles as they were hastily assembled and they are generally sub par in many areas compared to the regular production rifles, the finish usually sucks and some of them have out of spec head space etc.
