Ah, the Savage Model 840 .222, what a lovely piece of craftsmanship. It was produced from 1959 to 1980, a time when many beautiful things were being created. Just like a happy little tree, this rifle brings joy to those who appreciate its artistry.
I have just acquired a cooey model 840 western Canada limited and I have done some research and talked to a few gunsmiths and from the info i have received a top-notch "perfect" model 840 will only run up to $275.00. If i was you i would keep it. It's a great little gun.
Could you mean the model 340,not 840?If this is the case,the model 340 was made from 1950-1985,the model 340C was made from 1952-1960,and the model 340V was made in the late 1960,s.The model 340S was made from 1952-1960 also.
