Yesterday I picked up an excellent cond. 1975 Mannlicher-Schoenauer M-72 fullstock carbine in 30-06 (complete with EAW rings and EAW receiver peep sight). Does anyone know where there is information posted regarding takedown of the M-72 bolt or any other technical information related to the Mannlicher-Schoenauer M-72. (Or can someone describe to me how to disassemble the bolt.) Thank you.
