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”

    Sweet set of sights! I ordered these mistakenly, without fully reading that they are for a direct-mount slide cut, not a plate mount. I ordered the correct ones, and liked them so much, I decided to have a different slide cut to use the sights, and love the setup with an RMRcc. Definitely well worth the money, fit is excellent,, rear sight does not cut into my retention level 3 dunlap… due to the nicely melted edges.
