The Vortex Optics Crossfire II 4 - 12 x 44 mm Riflescope has low profile turrets, that are less susceptible to accidental impact damage and reset turrets, that allow re-indexing of the turret housing to zero after sighting in the riflescope - generally requires use of a coin or wrench.
The Dead-Hold BDC reticle helps eliminate guesswork on hold-over and windage corrections. It is good for hunting/shooting at varying ranges where estimating hold-over is a concern.
The solid one-piece aircraft-grade aluminum alloy construction of the Crossfire riflescope is outstanding in strength, rugged and shockproof. Neutral pressure nitrogen purging guarantees waterproofing and fog-proofing that withstands the elements at any elevation.
