I've owned a couple of the 70 XTR FWTs that were made for the European market. They have an open rear sight in a barrel dovetail and a ramp front sight. The also made a run of 70 XTR Sporters with higher sights that would work with the monte carlo style stocks. There were made in 1986/87. I took mine to Botswana and shot most of my plains game with it. They are throated for the longer 156/160 grain round nose bullets. I shot 156 grain Norma factory loads in mine.
