The only potential downside for the Dual Dovetails can be using up too much windage in scope if the mounting holes on the receiver are a bit wonky for alignment.
With good alignment and receiver contact, they make a nice, clean, sturdy setup.
Good shootin' -Al
Yep! alignment is key and wonky receiver/holes are a nemesis! Hung around too many machinist in my time.
Alignment is definitely key. So is buying good rifles where you don't have to worry about such things. Just sayin. I personally don't just use these on my Winchester model 70's:
They work just fine on other rifles as well. Tikka's shown below:
No alignment issues with these rifles either. ^^^^^ The Windage adjustable mounts go hand in hand with Remington 700's, old sporterized military rifles and Leupold scopes.
