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. Michael Gascon (verified owner)

    After ordering the wrong set, when these arrived, I wasbsonstoked, Indecide to keep the other ones (for a direct mount slide cut) and just have a slide cut for them. I love the Low-witness sight picture, just enough if my RMRcc goes down for some fluke of a reason.

    The rear sight has melted/radiused corners and are very comfortable for AIWB, even with a holster cut to allow a proper full-grip draw and not have your frontstrap riding the top of the belt like they’re its in heat.
