  • Multiple Reticle System: Multi-reticle System (MRS) equipped Holosun optics allow you to determine the type of aiming point you want to use when you want to use it.
  • Super LED: Super LED technology provides a versatile range of reticle intensity settings from night vision-compatible to daylight bright.
  • Multilayer Reflective Glass: Holosun’s use of Grade 5 Titanium in certain Elite category optics and laser devices results in unparalleled strength and durability.
