Features

  • Long range optic from 6-24x magnification and a 50mm objective lens allowing for more light transmission and a wider field of view
  • Fiber optic reticles differ from traditional etched or wire reticles in that the light source is channeled through a fiber optic filament to the center of the reticle to produce a daylight bright center dot, similar to that of a red dot.
  • 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: FIB04-MOA and FIB04-MIL 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.

Style: FIB04-MOA Reticle
100 bucks! Slapped this baby on a 6.5 Grendel. This piece of glass punched way over its price point. Clear good glass and the included mount how can you beat this deal. We zeroed the turret caps and the dial was was dead on. Very affordable excellent long range plinking scope. I just ordered a second for my 223 Wylde. Get these while you can. ... show more
