Not that older style mounts were bad or unusable, these are just a big upgrade.
I ran a tracking "box" test and the scope did. Very well. Tracked accurately and returned back to zero. The clicks are awesome. Seems very well made.
If your a serious target shooter, you will not be disappointed.
This mount is super duper improvement over the original mounts, they were mushy and too fine increments it made it hard to use .
But this new mount is built more robust and has very distinct and solid clicks.
The graduations on the turrets are very clear and very precise.
I also like the adjustable "0". Love this mount!!!
I am looking forward to shooting my next vintage sniper match !!!!
