A variable scope that gives you the best of both worlds. At 1x magnification, it can be used almost like a red dot while still giving you the option to zoom in 4x when you need to see more. Quick scope adjustments are easy even with gloves on. Illuminated reticle. Green & Red. CR2032 Battery Especially suitable for DMR setups for mid to long ranges. Eye Relief → 4.13 inch Tube Diameter → 25mm Comes with a metal, lightweight NATO/Picatinny mount. Features dioptric adjustment. The front glass element of this scope is thick enough to withstand regular BB impacts. We tested it with 1.5J point blank. BB marks on the glass can be wiped off with a cloth. This is just for your information, please be aware that we do not replace products damaged by BB shots or improper use.
