What's wild is that they had a good design on some of the fixed power military scopes they made in the 90s. They would track and hold zero. Not sure why they don't dig out the old design. I've had 2 personally fail that had to be sent in and repaired and had another buddies scope stop dialing on a hunt (they sent him a new scope). Just not worth the hassle of trying any more when there's much more reliable scopes.
