The Burris Handgun Scope is designed for handgun hunters who need a robust scope to handle the harshest recoil. The compact scope has a long eye relief ideal when hunting with a powerful handgun. The double internal spring tension system allows the scope to hold zero through shock recoil and vibrations; while positive steel-on-steel adjustments ensure repeatable accuracy. The scope has a 1 piece 1″ tube and is nitrogen-filled to prevent internal fogging. The index-matched multi-coated lenses maximize contrast in low-light settings while eliminating glare and providing superb clarity.
