Features

  • Mid power variable optic MPVO from 4-12x 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: FMR02 and FMR03 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.

  • Scope mount
Style: FIB01 Reticle
Don’t use the ring mount sent with it. It sits offset of the rifle does not clamp properly. Scope is great
