Offering both quick target acquisition and ammunition-specific hold points for longer shots, this Bushnell 1-6x24 AR Optics Riflescope is a versatile optic for your modern sporting rifle. You'll enjoy a bright, clear sight picture thanks to its fully multi-coated optics, and the illuminated BTR-1 reticle in the second focal plane shows holdover marks calibrated to the popular .223/5.56 cartridge with 55- to 62-grain bullets. The 100' maximum field of view makes it easy to find your target in competitions; when it's time to zoom in for a longer shot, generous elevation and windage adjustment ranges help compensate for bullet drop and cross winds. The 30mm, one-piece aluminum housing is waterproof and shock resistant, with 3.6" of eye relief. The Throw Down PCL zoom lever (short and long versions included) allows for rapid response to changing circumstances.
