We sell more "turn in rings" for regular hunting rifles than any other style. Not every gun we set up is for competition, tactical or long range shooting...in fact many guns sold are for hunting. Quality "turn in rings" allow us (and consumers who do their own mounting) the ability to center the scope on the base (or bases) using very little (if any) windage adjustment in the scope during initial mounting and bore sighting. This then allows the end user full range of adjustment in the scope itself during actual sighting in. "Turn in rings" are a little more difficult to install for people not experienced in scope mounting but for installers who mount scopes for a living they offer the most solutions to most mounting issues. We sell over 4000 guns a year and often mount scopes on many of those rifles. We have one of the largest selections of rings and bases in Edmonton (over $150,000 in parts alone in stock) so we also offer the full selection of choices and yes people still want "turn in rings".
