The Burris Handgun Scope is a compact scope with 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.
