Reliability in Adverse Conditions

Closed emitter red dot sights excel in dynamic tactical situations where field conditions can rapidly deteriorate while every shot has to count.

  • Our ACRO-patterned closed emitter has a 16mm lens diameter in a housing that measures just 47mmx35mmx32mm and weighs only 70.8 grams, keeping your weapon light and responsive.
  • Select from a 3 MOA dot for precision, a 38 MOA circle for rapid acquisition, or a combination circle dot reticle to maximize tactical flexibility.
  • Windage and elevation adjust at 1 MOA per click through a 45 MOA range each for a total adjustment range of 90 MOA.
  • Ready to install on ACRO pattern plates or with the included 1913 Picatinny rail mount for rifle or carbine use.
  • Made with 7075-T6 aircraft-grade aluminum for durability in the field.
  • The IPX7 waterproof, shockproof, and waterproof design keeps your sight ready for action in inclement weather.
  • Features ten levels of brightness adjustment, including two night-vision compatible levels and eight separate gradients for daytime use.
  • The power-saving shake-to-awake feature puts your sight in low-power mode after 225 seconds without movement, but the dot comes alive instantly with a shake or sharp motion, such as drawing the weapon.
  • A single CR-2032 3V Lithium battery can power your sight through up to 50,000 hours of service life under optimal conditions and can easily be changed without removing the sight thanks to the convenient side-load battery tray.
  • Parallax free up to 33 yards.
  • Our unmatched lifetime warranty stands behind our product against defects or almost any damage short of intentional abuse. If it stops working, we’ll replace it.
