I have had three of them. Two were the M70 Super Grades of about 1971 vintage. 22" barrels.
I picked up a supergrade.458 in the 80s, and it looked to have some age on it, so I gather it was something from the 70s Wasn't too impressed with the stock inletting, how were yours in that regard?
Agree, they were not that great in that regard, Although the checkering was very functional, being deep and sharp. They were vey business like looking rifles.
