The Truth About Using the Kensight Bomar BMCS Square Serrated Blade Adjustable Target 1911 Rear Sight
The world of 1911 customization is vast, and finding the right sights can dramatically alter a pistol’s performance. My search for a precise and reliable adjustable rear sight led me to the Kensight Bomar BMCS Square Serrated Blade Adjustable Target 1911 Rear Sight. After years of pushing equipment to its limits in diverse environments – from workshop benches to rugged outdoor settings – I was eager to see if this particular optic lived up to its promising specifications.
My immediate need for a new rear sight stemmed from a previous iteration that, while functional, lacked the fine-tuning capabilities required for consistent competition accuracy. I needed something that offered robust adjustments and a clear sight picture, even under pressure. While I briefly considered some more budget-friendly, fixed options, I ultimately decided that investing in a high-quality, adjustable sight would provide a better long-term solution for my needs.
Upon unboxing this Kensight rear sight, my initial impression was one of solid engineering. The wire-EDM manufacturing process was evident in the tight part-to-part fit, a detail often overlooked but critical for accuracy. The 4140 chrome moly steel construction, heat-treated to a respectable RC 38-40 hardness, suggested a level of durability that should withstand the rigors of frequent range use. This initial feel of quality provided a sense of cautious optimism, a quiet promise of precision.
Real-World Testing: Putting Kensight Bomar BMCS Square Serrated Blade Adjustable Target 1911 Rear Sight to the Test
First Use Experience
My first outing with the Kensight Bomar BMCS rear sight was at my local indoor range, specifically on a Caspian-built 1911 that I’ve been slowly refining. The installation was straightforward, fitting snugly into the existing Novak-style dovetail cut. The combination with a 0.100” wide, partially serrated blade and a 0.060” diameter fiber optic rod front sight (which was provided as a paired component) offered an exceptionally bright sight picture, drawing the eye naturally to the target.
During my initial range session, I focused on dialing in the windage and elevation adjustments. The detents felt crisp and precise, providing satisfying clicks with each turn, and importantly, they held their zero without any wandering. Testing in the controlled environment of the range allowed me to verify the accuracy of the adjustments. I experienced no surprises or quirks; the sight simply performed as advertised, offering a marked improvement in my ability to make precise shots.
Extended Use & Reliability
After several months of consistent use, including multiple range days, dry-fire practice sessions, and even a weekend carbine course where I used my 1911 as a secondary, the Kensight Bomar BMCS rear sight has held up exceptionally well. There are no signs of loosening adjustments, no visible wear on the blued finish despite being handled frequently, and the fiber optic rod remains bright and secure. Its performance has remained consistently accurate, reinforcing the initial impression of robust construction.
Maintenance has been minimal, which is always a plus. A simple wipe-down with a cleaning cloth after each range session is all that’s needed to keep it in pristine condition. Compared to previous, less robust adjustable sights I’ve used that developed play in their adjustments over time, this Kensight model feels significantly more durable and reliable. It certainly surpasses the performance and longevity I’ve experienced with more budget-friendly options, offering a solid middle ground between cost and premium functionality.
Breaking Down the Features of Kensight Bomar BMCS Square Serrated Blade Adjustable Target 1911 Rear Sight
Specifications
The Kensight Bomar BMCS Square Serrated Blade Adjustable Target 1911 Rear Sight is a testament to precision manufacturing. It is constructed from 4140 chrome moly steel, a robust material chosen for its strength and durability in firearms components. The manufacturing process utilizes the wire-EDM process for major components, ensuring tight part-to-part fit and exceptional accuracy.
This rear sight is designed to pair with a specific front sight, featuring a contoured base fiber optic blade. The fiber optic rod itself is 0.060” in diameter, offering superior visibility and quick sight acquisition. The blade width is a standard 0.100”, and it is partially serrated to reduce glare.
The base of the rear sight is flat, making it ideal for pistols with a flat-topped slide or for custom filing to match a specific slide contour. This specific model is compatible with Novak type front sight dovetail cuts (0.330″ x 65 x 0.075″), a common standard on many customized and factory 1911 pistols. The hardness of the 4140 chrome moly steel is heat-treated to RC 38-40, ensuring it can withstand significant impact and wear.
Performance & Functionality
The primary function of any adjustable target sight is to allow for precise zeroing and repeatable accuracy, and the Kensight Bomar BMCS excels here. The windage and elevation adjustments are tactile and precise, with distinct clicks that confirm each movement. This granular control is crucial for competitive shooting or any application demanding pinpoint accuracy, allowing shooters to fine-tune their point of impact with confidence.
In terms of performance, the bright fiber optic front sight complements the adjustable rear sight perfectly. It significantly enhances visibility, especially in varied lighting conditions, making target acquisition faster and more intuitive. While the serrated blade on the rear sight is a nice touch to minimize glare, the overall sight picture is clear and uncluttered. Its main strength lies in its ability to provide consistent, repeatable adjustments, which is exactly what you need for a target sight.
Design & Ergonomics
The design of this Kensight rear sight is classic Bomar-style, focusing on functionality and adjustability. The use of 4140 chrome moly steel provides a substantial feel, indicative of quality and durability. The wire-EDM machining results in crisp edges and a precise fit, which translates to a solid, integrated feel once installed.
Ergonomically, the sight is designed for its intended purpose on a target pistol. The adjustment knobs are accessible without being overly obtrusive, and the serrated blade offers a good grip for fine-tuning. The flat base is a practical design choice, catering to a common slide profile or allowing for custom fitting. The overall aesthetic is functional and no-nonsense, prioritizing performance over flash.
Durability & Maintenance
Based on the materials and construction, this Kensight rear sight is built for long-term durability. The 4140 chrome moly steel is a proven material for firearm components, and the RC 38-40 heat treatment further enhances its resistance to wear and impact. The wire-EDM process contributes to the overall integrity of the sight by ensuring precise mating surfaces that are less prone to developing play.
Maintenance is thankfully straightforward. A simple wipe-down to remove residue and dust is generally sufficient. The enclosed adjustment mechanisms help protect them from debris, reducing the need for more intensive cleaning. As with any firearm component, keeping it clean and free from excessive moisture will ensure its longevity and continued precise operation.
Accessories and Customization Options
The Kensight Bomar BMCS Square Serrated Blade Adjustable Target 1911 Rear Sight is typically sold as a unit, often paired with a compatible front sight as described. In my case, the front sight with its contoured base fiber optic blade was included, which simplifies the upgrade process by providing a matched set. Compatibility with Novak type front sight dovetail cuts is a key aspect, meaning it will integrate well with a vast number of existing 1911 platforms.
While this model doesn’t come with a plethora of additional accessories, its strength lies in its own well-executed design and functionality. The fiber optic rod is a significant functional enhancement, providing superior visibility without needing external batteries or complex electronics. The partially serrated blade on the rear sight is a subtle but effective design element that aids in glare reduction.
