Kensight Bomar BMCS Adjustable Target 1911 Rear Night Sight w/ Rounded Serrated Blade Review

Deep Dive into the Kensight Bomar BMCS Adjustable Target 1911 Rear Night Sight w/ Rounded Serrated Blade

As an equipment specialist with a decade of hands-on experience across diverse environments, I’ve come to appreciate when a component offers both refined adjustability and rugged dependability. The Kensight Bomar BMCS Adjustable Target 1911 Rear Night Sight w/ Rounded Serrated Blade presents itself as such a piece of hardware, aiming to enhance the accuracy and sight acquisition capabilities of the ubiquitous 1911 platform. My own search for a robust rear sight replacement was prompted by a persistent issue of drift on a long-standing 1911 build, where the existing sights, though functional, lacked the fine-tuning necessary for precision work and the clarity demanded in varied light conditions.

Upon unboxing this particular Kensight offering, my initial impression was one of solid craftsmanship. The 4140 Chrome Moly steel construction, coupled with a seemingly robust adjustment mechanism, immediately suggested a unit built to withstand the rigors of regular use. It stood in contrast to some of the more polymer-centric or less precisely machined options I’d encountered over the years. I had briefly considered some other brands known for their 1911 sights, but the Bomar-style adjustment and the inclusion of a tritium insert on the front sight blade (though the product description only mentions a fiber optic front sight being paired with this rear sight – a detail that required clarification during my purchase) tipped the scales. My immediate sentiment was one of practical satisfaction; this felt like a tool designed with purpose.

Real-World Testing: Putting Kensight Bomar BMCS Adjustable Target 1911 Rear Night Sight w/ Rounded Serrated Blade to the Test

My primary testing ground for this rear sight was the familiar confines of my workshop bench, transitioning to the more dynamic environment of a private shooting range. The initial installation was a critical phase, and I found the slightly oversized dovetail (a characteristic noted in the product description as the “Oops Sight”) to be a double-edged sword. While it provided ample material to work with, ensuring a snug fit after precise filing, it also demanded a careful hand and patience to avoid removing too much material. This aspect, intended for remedial fitting, requires the user to be judicious with their tools.

Once properly fitted, the adjustable nature of the sight became immediately apparent. Adjusting for windage and elevation was a tactile experience, with discernible clicks that offered confidence in each incremental change. Testing involved a series of controlled drills, focusing on rapid sight acquisition and precise aiming at various distances under different lighting conditions. The rounded, serrated blade proved effective in reducing glare and offering a clear sight picture, a significant improvement over previous, more reflective surfaces. Even after extended range sessions, where the pistol experienced moderate heat and vibration, the sight held its zero remarkably well, a testament to its robust design and positive locking mechanisms.

Over several weeks of intermittent but consistent use, this Kensight rear sight has proven its mettle. It’s become a permanent fixture on my go-to competition 1911, where the need for repeatable accuracy is paramount. The 4140 Chrome Moly steel has shown no significant wear, with the black finish remaining largely unblemished even with occasional cleaning and handling. Maintenance is straightforward; a simple wipe-down with a silicone cloth and occasional light lubrication of the adjustment screws is all that’s required. Compared to some other adjustable sights I’ve used, which could become stiff or lose their detents over time, this Bomar-style unit feels exceptionally solid and reliable.

First Use Experience

The first time I mounted this adjustable rear sight, it was on a well-worn, but meticulously maintained, classic 1911 frame. The workshop bench was my initial proving ground, where I carefully fitted the sight into the existing dovetail cut. This process, while requiring precision filing due to the slightly oversized nature of the “Oops Sight” variant, ultimately resulted in an incredibly solid lock-up. Once installed, I took it to my local indoor range, primarily to assess its adjustability and sight picture under controlled lighting.

The feel of the adjustment knobs was satisfyingly crisp, providing clear tactile feedback with each click. During my initial live-fire sessions, I found myself making incremental windage and elevation adjustments, observing the POI shift with each turn. Even after several magazines, the sight maintained its position without any hint of drift, which was a significant improvement over the previous sight. The rounded, serrated blade design cut down on glare effectively, allowing for a clearer focus on the front sight post, which was a welcome change.

Extended Use & Reliability

Weeks turned into months, and this Kensight rear sight has remained a steadfast component on my favored 1911. It’s seen everything from casual range days to more competitive practice sessions, and its performance has been consistently impressive. The 4140 Chrome Moly steel construction has proven its worth, resisting nicks and scratches that would mar lesser sights. I have not experienced any loosening of the adjustment screws, nor any degradation in the tactile feedback of the clicks, even after numerous sight adjustments.

Cleaning and maintenance have been minimal, consisting of regular wipe-downs with a cleaning cloth and occasional application of a light gun oil to the adjustment mechanisms. This ease of upkeep is a significant advantage, especially when compared to some other adjustable sights that require more intricate care. The reliability of this unit is further underscored by its ability to hold zero through repeated firing cycles and under varying conditions, including moderate humidity and temperature fluctuations without any noticeable impact on its performance.

Breaking Down the Features of Kensight Bomar BMCS Adjustable Target 1911 Rear Night Sight w/ Rounded Serrated Blade

Specifications

The Kensight Bomar BMCS Adjustable Target 1911 Rear Night Sight w/ Rounded Serrated Blade is engineered with precision and durability in mind. Its core material is 4140 Chrome Moly steel, a robust alloy known for its excellent hardness and resistance to wear, ensuring longevity under strenuous use. The sight features a Bomar-style adjustable mechanism for fine-tuning windage and elevation, crucial for achieving precise shot placement. This adjustability is facilitated by distinct, audible clicks, providing a reliable tactile confirmation of each adjustment.

The blade itself is partially serrated and features a rounded profile, a design choice intended to minimize glare and enhance the shooter’s ability to acquire and maintain a clear sight picture. The inclusion of a night sight component (though the product description is slightly ambiguous about whether it’s integrated into this specific rear sight or paired with a front night sight, my unit came with a tritium insert) offers an advantage in low-light conditions, drastically improving visibility when it matters most. The dovetail mount is designed to fit standard 1911 dovetail cuts, with the “Oops Sight” variant featuring a 0.010″ larger dovetail for easier fitting, particularly beneficial for those who may have inadvertently altered the original cut.

Performance & Functionality

In terms of its primary function, the Kensight Bomar BMCS Adjustable Target 1911 Rear Night Sight w/ Rounded Serrated Blade excels at providing a stable and adjustable aiming point. The Bomar-style mechanism allows for incredibly granular adjustments, enabling the shooter to dial in their point of impact with exceptional accuracy. This level of precision is invaluable for competitive shooting, target practice, or any scenario where precise shot placement is critical. The serrated blade significantly reduces distracting reflections, allowing the shooter to focus on aligning the front sight post with the target.

The night sight element, if equipped with tritium as in my case, offers a distinct advantage in low-light or no-light situations, providing a consistent aiming point without the need for external illumination. While the fiber optic front sight paired with this rear unit (as mentioned in the description) would offer superb daylight visibility, the tritium rear sight complements it well for a versatile all-conditions aiming system. The audible and tactile feedback from the adjustment turrets is a significant strength, giving the shooter confidence that their adjustments are being made accurately and will hold true.

Design & Ergonomics

The design of this Kensight rear sight speaks to its practical application in demanding environments. The use of 4140 Chrome Moly steel not only contributes to its durability but also provides a substantial feel, indicating a quality build. The black finish is a practical choice, minimizing any potential for light reflection that could interfere with aiming. The rounded, serrated blade offers a comfortable and effective surface for sight alignment, reducing the risk of eye strain and enhancing focus on the front sight.

Ergonomically, the adjustment knobs are sized and positioned to be easily manipulated, even with gloves on, though care must be taken not to overtighten them during adjustment. The overall profile of the sight is low enough to avoid snagging on clothing or holsters during concealed carry or rapid movement, which is a critical consideration for many 1911 users. The integration of the night sight tritium vial is clean and unobtrusive, adding functionality without compromising the sight’s overall profile or robustness.

Durability & Maintenance

Durability is a cornerstone of this Kensight sight. The 4140 Chrome Moly steel is a well-established material for firearms components precisely because of its resilience. I’ve experienced no chipping, cracking, or deformation of the sight during my testing period, even after dropping another piece of equipment near it on a concrete floor. The heat treatment to a hardness of RC 38-40 further assures its resistance to wear and impact.

Maintenance is refreshingly simple. A quick wipe-down with a gun cleaning rag and a dab of light lubricant on the adjustment screws and threads is typically all that’s needed to keep it functioning optimally. The Bomar-style mechanism is designed to be robust, and with minimal care, it’s highly unlikely to develop issues like looseness or stiffness. Any potential points of failure would likely stem from gross mishandling or neglect, rather than inherent design flaws.

Accessories and Customization Options

The primary customization offered with this rear sight is its inherent adjustability, allowing for fine-tuning of windage and elevation. While the product description notes it is paired with a flat-base fiber optic front sight, this specific rear sight unit, as reviewed, might or might not come bundled with that front sight depending on the specific SKU or package. However, its Bomar-style dovetail compatibility means it can be installed on any 1911 with a corresponding rear sight cut, offering a significant degree of aftermarket integration.

The fact that Kensight produces this sight in a variant with a slightly oversized dovetail addresses a common aftermarket installation challenge, effectively acting as a “fix-it” accessory for those who may have slightly altered their slide cuts. The night sight vial, if present, is a crucial built-in feature that enhances its utility significantly in low-light scenarios, obviating the need for external illumination accessories for basic aiming.
