The Sharpshooter also includes Weaver-style aluminum rings in the box that will work on both Weaver and Picatinny rails to get you mounted up and on the range fast and without the additional cost. Bushnell riflescopes are constructed of a one-piece tube made of aircraft-grade aluminum, and are watertight and nitrogen-purged so you won't have to worry about fogged up glass or failed seals when you're out at the deer stand.
