Does the Kensight DAS Adjustable Elevation Only Rear 1911 Night Sight Deliver?
For years, my go-to for reliable 1911 sights has been functional, no-nonsense iron sights. However, the dim light conditions on the range and the increasing frequency of low-light defensive shooting drills pushed me to explore night sight options. After much deliberation, I landed on the Kensight DAS Adjustable Elevation Only Rear 1911 Night Sight, a promising blend of durability and illuminated aiming points. This particular model caught my eye due to its adjustable elevation, a feature I often find myself needing for precise zeroing at varying distances. My previous sight, a standard fixed rear, was accurate but lacked the fine-tuning capability for rapid target acquisition across different ranges.
Initial impressions upon unboxing were strong. The sight feels substantial, machined from what appears to be robust 4140 Chrome Moly Steel. There’s a satisfying heft to it, suggesting it can withstand the rigors of a workshop or a demanding range day. The serrated blade is clean, and the tritium dots appear properly seated. I had considered a different brand that offered both windage and elevation adjustments, but for my specific needs on a particular 1911 platform, an elevation-only adjustment was more practical and often less prone to accidental bumps. My first reaction was one of confident anticipation – it looked and felt like a serious piece of equipment.
Real-World Testing: Putting Kensight DAS Adjustable Elevation Only Rear 1911 Night Sight to the Test
My testing grounds for this optic were primarily the indoor pistol range during evening hours and extended range sessions during daylight. I specifically chose scenarios that mimic both defensive practice and target shooting. This involved drawing from a holster and acquiring a sight picture under artificial lighting, as well as fine-tuning the zero at 25 and 50 yards. I also subjected it to a few simulated workshop dust environments and a light drizzle during an outdoor range day to gauge its resilience.
The ease of use was surprisingly intuitive. While I’ve worked with adjustable sights before, the Kensight’s mechanism felt familiar. Adjusting the elevation was straightforward, requiring only a small tool (often a punch or a specific driver) to turn the adjustment screw. The tritium dots glowed consistently in low light, providing a clear aiming point without needing to charge them with external light. My only minor quirk was the initial sight-in process, which always takes a few magazines to dial in perfectly, but that’s standard for any adjustable sight.
Extended Use & Reliability
After several months of consistent use, the Kensight DAS Adjustable Elevation Only Rear 1911 Night Sight has proven its mettle. It has been re-zeroed several times due to ammunition changes and range requirements, and the adjustment mechanism remains crisp and holds its setting reliably. There are no signs of looseness or wear on the serrations or the tritium vials. It has endured being racked on holsters and the occasional bump against a workbench without any visible damage or degradation in performance.
Compared to other rear sights I’ve used, this unit strikes an excellent balance between robust construction and functional adjustability. Cheaper plastic sights tend to degrade or lose zero more easily, while some high-end target sights can be overly complex for general use. The Kensight offers a solid, middle-ground solution. Cleaning is as simple as wiping down the slide and ensuring the lens over the tritium is clear; no special care is required.
Breaking Down the Features of Kensight DAS Adjustable Elevation Only Rear 1911 Night Sight
Specifications
The Kensight DAS Adjustable Elevation Only Rear 1911 Night Sight is crafted from 4140 Chrome Moly Steel, a material renowned for its strength and durability, suitable for harsh environments. The rear sight features a serrated blade design, which is crucial for reducing glare in bright light. It incorporates Trijicon tritium 0.076″ dots for low-light visibility, offering a reliable aiming point that glows without batteries for up to 12 years. This specific model is elevation adjustment only, simplifying its use for shooters who primarily need to manage bullet drop.
The sight is designed to fit the popular Novak LoMount rear sight dovetail cut, a common dimension found on many 1911 pistols from manufacturers like Springfield Armory, Colt, Wilson Combat, and others. This universal fit makes it a versatile upgrade. The accompanying front sight, typically sold separately or as a set, is often a 0.200″ tall front sight with a tritium dot, designed to pair with various blade heights for a perfectly zeroed system. The dovetail cut for the front sight is specified as 0.330″x 65 x 0.070″, indicating precise machining requirements.
Performance & Functionality
The core function of any rear sight is to provide a clear, reliable aiming point, and this Kensight unit excels here. The tritium dots offer a distinct advantage in transitional light and complete darkness, making target acquisition significantly faster and more precise than with standard iron sights. The serrated blade effectively diffuses light, preventing distracting reflections that can obscure the sight picture. The adjustable elevation allows for precise point-of-aim/point-of-impact adjustments, which is indispensable for shooters who demand accuracy at various distances.
Its primary strength lies in this dual capability: effective low-light sighting and precise point-of-impact adjustment. While it lacks windage adjustment, which some shooters might desire for extreme precision, for defensive carry and general target shooting, managing elevation is often the more critical factor. This focused design streamlines the adjustment process and reduces the potential for user error. It reliably meets and often exceeds expectations for a night sight in this price bracket.
Design & Ergonomics
The design of the Kensight DAS is decidedly utilitarian, prioritizing function over elaborate aesthetics. The 4140 Chrome Moly Steel construction lends it a robust, almost rugged feel. The finish is typically a matte black, which is non-reflective and blends well with most firearm finishes. The serrations on the rear blade are well-defined, providing good contrast against the tritium dots.
Ergonomically, it’s a standard rear sight, meaning its integration depends heavily on the pistol’s slide profile. However, the absence of sharp edges or protrusions makes it snag-free, ideal for concealed carry or tactical operations. The adjustment mechanism, while requiring a tool, is well-recessed, minimizing the chance of accidental adjustment. The tritium dots, being small and precisely placed, offer a clear sight picture without overwhelming the target.
Durability & Maintenance
Given its 4140 Chrome Moly Steel construction, this sight is built for longevity. Under normal use, it should last for many thousands of rounds and years of service. The Trijicon tritium vials are rated for approximately 12 years of illumination, after which they can typically be replaced by Kensight or a specialized service.
Maintenance is minimal. A simple cleaning with a soft cloth and a mild solvent to remove fouling or debris is usually sufficient. It’s important to avoid harsh abrasives that could damage the finish or the tritium vial’s protective coating. The adjustment screw threads are robust, but it’s always good practice to use the correct tool to avoid stripping them. There are no apparent weak points that suggest premature failure.
Accessories and Customization Options
This specific model focuses on the rear sight itself. While it often comes as part of a set with a matching front sight, the rear sight’s primary customization comes from its adjustable elevation. Compatibility is key here; it’s designed to fit the Novak LoMount rear sight dovetail cut, meaning it will work with many factory and custom 1911 slides cut for this common dovetail.
The accompanying front sights, typically sold in sets, are usually designed to work in conjunction with the rear sight’s blade height for proper zeroing. For instance, Kensight often pairs this rear sight with a 0.200″ tall front sight with a tritium dot, but they offer a range of front sight heights (from 0.150″ to 0.210″) allowing shooters to fine-tune their sight radius and point of impact if the standard pairing doesn’t match their specific firearm or preferred load. The front sight typically requires a 0.330″x 65 x 0.070″ dovetail.
