Hello mike,

A quick response as I really get on a soap box when it comes to scopes. As for Leupolds I can only go by personal experience here, I use to guide in Wyoming so I see a fair amount of shots fired. I also do a fair amount of gun work so fire alot of shots as well. By far the largest number of QUALITY scopes I see fail to track or hold zero are Leupolds. Nothing else comes close. I have used Zeiss for 20+ years and never once sent one for repairs. I have never had a leupold of my own that didn't get sent back. The most common failure we see is a wondering zero on a upper right to lower left stringing of shots. I think they make a decent 200.00 scope, problem is they are twice that and still not a Burris or Nikon toughness wise.

There Mark 4's are tough I guess but have heard that the Scout Sniper scholl at Benning is using 10x Henstolds and Tasco's again.

I don't own a single Leupold scope anymore. For a hunting gun where I need/want a minimal amount of added weight I use Zeiss, on tactical/target guns I use I.O.R or NightForce.
