Description
This is Kensight's DAS (Defensive Adjustable Sight) built for 1911 pistols cut for the Novak LoMount dovetail. It gives you full click-adjustable windage and elevation, so you can dial in your point of impact without guessing, and the whole body is rounded and dehorned with no sharp corners to bite your hands or grab clothing on the draw. That combination of precision and a smooth exterior is what makes it a favorite for carry guns that still need to shoot to point of aim.
What Sets the Kensight DAS Rear Sight Apart
The sight body is Wire-EDM machined from 4140 chrome-moly steel and heat treated to a hardness of RC 38-40. That process holds tighter tolerances than typical CNC work, which means consistent dovetail dimensions, an audible click on every adjustment, and a sight that shrugs off years of slide cycling and holster wear. It is the kind of part you install once and forget about.
Sight Picture on the DAS White Dot
The blade is partially serrated and slanted to knock down glare, and there is a high-visibility white dot on each side of the notch. The two dots frame the rear notch and pull your eye straight to the front post, which speeds up target acquisition in a defensive or range setting. It is a clean two-dot setup that works well in daylight and does not clutter your view.
Fitting the Kensight LoMount Sight
This one drops into an existing Novak LoMount rear dovetail found on many factory and custom 1911s, including certain Colt, Springfield, Wilson Combat, Les Baer, STI, Rock River, and Dan Wesson models. Because these are cut to tight tolerances, the dovetail often runs slightly oversized and needs to be fitted, so a sight pusher or a trip to your gunsmith is the way to go for a rock-solid, centered install. Confirm your slide is cut for the Novak LoMount pattern before ordering.

Frequently Asked Questions
What pistols will the Kensight DAS rear sight fit?
It fits 1911 slides machined for the Novak LoMount rear sight dovetail cut. That covers many factory and custom guns, including certain Colt, Springfield Armory, Wilson Combat, Les Baer, STI, Rock River Arms, and Dan Wesson 1911s. Check that your slide has the Novak LoMount pattern before ordering, since it will not work with other dovetail cuts.
Is the Kensight DAS a drop-in sight or does it need fitting?
Kensight cuts these to tight tolerances, so the dovetail often runs a touch oversized and needs to be fitted for a centered, secure hold. Most people use a sight pusher or hand the job to a gunsmith rather than tapping it in with a punch. That extra step is what gives you a sight that stays put and holds zero.
Does this rear sight adjust for both windage and elevation?
Yes. This DAS model is fully adjustable for both windage and elevation with positive, audible clicks. That lets you fine-tune point of impact for different loads and get your groups centered without swapping parts.
Will the Kensight DAS rear sight work with my current front sight?
Because this rear sight sits a bit taller than a standard adjustable, it needs a front sight of the right height to shoot to point of aim. Many users pair it with a Kensight standard front sight cut for the common 0.330 inch Novak-style front dovetail. If you are unsure about your front sight height, a gunsmith can help you match the pair.
