Style: FIB01 Reticle


Features

  • Mid power variable optic MPVO from 3-12x magnification and a wider 44mm objective lens allowing for more light transmission and a wider field of view
  • Features a fiber optic reticle with a fiber optic tube that runs along the back of the crosshair to channel light from an LED light source to the center of the reticle. This allows it to generate a daylight bright center dot many times brighter than those found in more commonly used etched or wire illuminated reticle systems.
  • Includes a side focus parallax adjustment dial - that allows for sharper focus of the target image, elimination of parallax, and range estimation
  • Available in multiple newly designed second focal plane options: FIB01, FIB02 and FIB03 reticle. Second focal plane reticles remain the same size at all magnification levels for high visibility at all magnifications.
  • Scope comes in a 30mm tube configuration and includes a Monstrum one piece cantilever scope mount. Also comes with a set of bikini lens covers.

  • Great optics value.
Style: FIB02 Reticle
Clear glass at all magnifications. Tracks well and time will show the zero hold ability but I expect it to preform well. All adjustments turn smoothly but are stiff enough to hold settings. You can't beat the price and would definitely purchase again. Great look and quality.
