Get a Nikon Monarch 3....even Pro Staff and Sluggun will hold up to heavy recoil better compared to Leupolds and better eye relief.

Myself and several other people are using them on large bore lightweight rifles weighing less that 8 pounds, 375 up to 500 caliber. In 3 years and thousands of full power rounds not one has broken. Usually in one year 5-12 Leupolds would be going back for repairs.
