C&H Precision BUIS (Back Up Iron Sights) were specifically designed to be used with the OEM Optic Ready Slides and Direct Milled Slides.

LowWitness is defined as a BUIS (Back Up Iron Sights) that sits between .075″ to .100″ into the optic FOV (Field Of View) which is equivalent  to lower 1/6 to lower 1/8.

True Co-Witness blocks half of your red dot visible window / FOV while Lower Third blocks one third of your visible window / FOV.

Red Dot Industry Experts believe Back Up Irons should not be a vision blocker and should be as low as possible but still useable if needed.

LowWitness® Back Up Iron Sight heights provide you the lowest usable sight height without being a vision blocker “Everything you need, nothing you don’t”

  1. Joshua Movich (verified owner)

    Great Irons! Perfect height for about a lower 1/4 witness, not in my way but there if i need them.

  2. Grant Kendall (verified owner)

    Great sights, easy install feel durable. I have an MOS glock with an Aimpoint Acro and the the sights take up less room in the window than Trijicon Suppressor height sights and you can see them fine in the lower 1/5th basically
