My first centerfire rifle was a .243 Remington 700ADL 20" carbine w/iron sights.
I bought it, used, in Massachussets when I got discharged from the service in 1966, for $95 in excellent condition.
I ended up adding a contrasting wood forend tip & PG cap, in the style of the day, and installing a BDL floorplate/magazine after ordering the parts from Remington's Parts Dept..
