The Patriot precision rifle scope is 100% battery free and delivers the performance your rifle deserves. The optimized internal design maximizes eye box, a clear sight picture from edge to edge, even at high magnification. Use the included low- or high-profile throw fins to make instant magnification changes. The zero-re-settable target turrets feature crisp, tactile and audible clicks calculated to match the Sharpshooter MOA or Sharpshooter MRAD first focal plane reticle with either 0.25 MOA or 0.1 MRAD adjustment per click. The Patriot delivers worry-free use in hunting, tactical, or competition shooting.
