Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights Review

Getting Up Close with the Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights

As an equipment specialist with over a decade of experience across diverse environments, I’ve learned that the devil, or in this case, the accuracy, is often in the details – especially when it comes to pistol sights. My quest for improved target acquisition led me to the Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights. The small frame Glocks, particularly the 42, 43, 43X, and 48, are popular choices for concealed carry and personal defense, but their stock sights can sometimes leave something to be desired, especially under stress or in low light. I was specifically looking for a taller sight profile to better co-witness with a red dot optic on my G43X MOS, and a more robust, snag-free design for EDC. After a quick look at other options, such as Trijicon HD XR or AmeriGlo Trooper sights, the Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights caught my eye due to their promising combination of construction, de-horned design, and the allure of fiber optics at a very attractive price point. My initial impression upon unboxing was positive; the sights felt solid, with a pleasing matte black nitride finish that exuded durability, promising a significant upgrade from the often plastic-feeling factory sights. This compact sight set arrived promising enhanced visibility and a smoother draw, making it an exciting prospect for refining my shooting game.

Real-World Testing: Putting Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights to the Test

First Use Experience

My testing began at an indoor range, a familiar haunt for evaluating pistol upgrades. I installed the Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights on my Glock 43X MOS. The installation itself was straightforward, mirroring the process for most Glock sights, requiring a sight pusher tool. The rear sight seated snugly into the dovetail, exhibiting a satisfyingly tight fit that instilled confidence in its stability. The front sight, too, was secure, with the included screw holding firm. The initial experience at the range was marked by a noticeably brighter sight picture thanks to the fiber optic inserts. Even under the range’s artificial lighting, the green front sight rod popped, drawing my eye naturally to the aiming point. Shooting drills, including rapid fire and deliberate precision shots, were all executed smoothly. The taller profile was immediately apparent, providing a better line of sight above the RMRcc, crucial for that intended co-witness capability. There were no snags during presentation from a holster, confirming the de-horned design’s effectiveness. One small quirk I noted immediately was that the bottom edge of the rear sight protruded slightly (about 1/16 to 1/8 inch) past the rear of the slide. While not affecting functionality or snagging, it’s an aesthetic detail worth mentioning.

Extended Use & Reliability

Over several weeks, these Angry Bear Arms sights transitioned from range novelty to a dependable EDC component. I carried my Glock 43X daily, drawing and re-holstering countless times in various environments – from the controlled environment of my workshop to the bustling chaos of everyday life. The sights consistently performed without issue, their snag-free design proving its worth repeatedly during concealed carry draws. The black nitride finish has held up remarkably well, showing no signs of significant wear despite daily contact with holsters and clothing. Cleaning and maintenance have been minimal; a quick wipe-down with a soft cloth after a range session or a dusty day is all that’s required. Compared to other aftermarket sights I’ve used, including some much pricier options, these bear Bones sights have demonstrated impressive resilience and consistent performance. The fiber optic rod remains bright, and the overall structural integrity feels robust. Unlike some budget sights that can loosen over time, these have maintained their tightness in the dovetails, indicating solid machining and proper fitment. I did notice one user comment mentioning a rear sight with no optics, which seems like an anomaly, as my set, and the product description, clearly indicate fiber optic inserts. My experience has been exclusively positive regarding the optical clarity and illumination of the rods.

Breaking Down the Features of Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights

Specifications

The Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights are engineered for Glock small frame pistols, specifically models Glock 42, 43, 43X, and 48. Constructed from billet alloy steel, these sights promise significant durability and resistance to wear. They feature a black nitride finish, which not only provides corrosion resistance but also contributes to a glare-free surface crucial for aiming. The defining characteristic is their fiber optic illumination, with included green and red fiber optic rods, allowing users to customize the front sight color for optimal contrast against different backgrounds. The front sight blade height is specified at 0.305 inches, and the rear blade at 0.31 inches, creating a “tall profile” suitable for co-witnessing with red dot sights or simply providing a more prominent sight picture. The design is explicitly snag-free, with de-horned edges on both front and rear sights to ensure a smooth draw from concealment. The attachment type is a standard dovetail mount, secured with screws, which is common and reliable for Glock pistols. The package includes essential mounting hardware and spare fiber optic rods, making it a complete solution for upgrading your pistol’s sights.

The billet alloy steel construction is a significant advantage, offering superior strength and longevity compared to many polymer or softer metal sights. This ensures they can withstand the rigors of daily carry and frequent range use without deforming or breaking. The black nitride finish is more than just aesthetic; it’s a highly durable surface treatment that resists scratches, rust, and, importantly, glare. In bright sunlight or under harsh artificial light, a non-glare finish is paramount for maintaining a clear sight picture, and this nitride finish excels at that. The fiber optic technology is a standout feature, especially at this price point. Unlike tritium sights that glow continuously but can dim over time and are expensive, fiber optics gather ambient light and channel it into a bright, highly visible dot. The inclusion of both green and red rods is a thoughtful touch; green is typically the most visible color for most people in most lighting conditions, but red can be preferable in certain situations or for shooters who find green distracting. This flexibility allows users to tailor the sight to their personal preference and shooting environment. The “tall profile” aspect is critical for Glock owners who mount red dot sights. These taller sights allow the iron sights to be visible through the optic’s window, providing a reliable backup if the electronic sight fails or is obstructed. This “co-witness” capability is a major functional benefit for those relying on their firearm for self-defense or serious training. Finally, the snag-free, de-horned design is a hallmark of quality defensive pistol sights. The sharp edges of traditional sights can catch on clothing, holsters, or even skin during a draw, potentially slowing you down or causing a failed presentation. Angry Bear Arms’ attention to this detail ensures that drawing your weapon will be as smooth and fast as possible.

Performance & Functionality

In terms of pure function, the Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights deliver on their promise of improved target acquisition. The fiber optic front sight is exceptionally bright, drawing the eye immediately and making it easy to find your front sight quickly, even during dynamic shooting exercises. The contrast between the bright green front sight and the black rear sight creates a clear, easy-to-align picture. My experience at the range confirmed this; target transitions were faster, and follow-up shots were more consistent because I was able to reacquire the front sight rapidly. The tall profile works exactly as intended for co-witnessing; when looking through the RMRcc on my G43X MOS, the top of the front sight post aligns perfectly with the bottom of the red dot, offering a solid backup aiming point. This functionality is critical for anyone running a red dot on a defensive pistol. The snag-free design is not just marketing hype; during multiple draws from my EDC holster, the sights glided smoothly without any hint of catching on fabric or the holster opening. This is a significant improvement over the factory sights, which have sharper edges.

However, there are minor areas for improvement that prevent these sights from being absolutely perfect. One user feedback mentioned a rear sight with no optics, which is concerning and suggests a potential quality control issue in a very small percentage of units, though not something I encountered. My main observation, as noted earlier, is the slight overhang of the rear sight base on the back of the slide. While it doesn’t impede function, it’s an aesthetic detail that might bother some users who prefer a perfectly flush fit. Additionally, while the fiber optic is excellent in good light, it will not glow in complete darkness like tritium sights. For true low-light or no-light situations, an alternative sight setup or weapon-mounted light would still be necessary. Despite these points, for their intended purpose of enhancing visibility in day or illuminated conditions and providing a reliable backup to optics, they perform exceptionally well. They meet and often exceed expectations for their price category, offering a substantial upgrade in terms of visibility and defensive utility.

Design & Ergonomics

The design of the Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights is clearly focused on practicality and defensive use. The billet alloy steel construction lends a substantial, high-quality feel, a stark contrast to the lightweight plastic many Glocks come with. The black nitride finish is not only functional but also aesthetically pleasing, giving the firearm a more tactical appearance. The edges are expertly de-horned; running a finger over them reveals a smooth, rounded profile that feels safe for concealed carry and drawing. This attention to detail in the ergonomics is evident and contributes significantly to the user experience. The sight picture itself is clean; the black rear sight blades are serrated (though not explicitly mentioned in the description, it’s a common feature for glare reduction on rear sights and is implied by the glare-free finish) providing good contrast with the bright fiber optic front sight, minimizing distraction. The slightly taller profile is ergonomic in the sense that it naturally guides the eye to the correct sight picture, especially when co-witnessing with a red dot. There is no real learning curve associated with these sights; their operation is intuitive and mirrors standard iron sight usage. The only slight ergonomic anomaly is the minor rear sight overhang, which, while not a functional issue, breaks the otherwise clean lines of the slide.

Durability & Maintenance

Durability is where the Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights truly shine, especially given their accessible price point. The billet alloy steel construction means these sights are built to endure significant abuse. I’ve personally dropped other firearms with aftermarket sights onto concrete, and while the gun might sustain cosmetic damage, robust steel sights like these are unlikely to fail. The black nitride finish is exceptionally tough and resistant to scratching and corrosion. After weeks of consistent EDC, the finish shows no signs of wear or chipping, which is impressive. Maintenance is as simple as it gets for firearm components. A quick wipe-down with a clean, dry cloth or a lightly oiled cloth after exposure to moisture is sufficient. The fiber optic rods are relatively durable but can be fragile if subjected to direct impact or excessive force, though they are well-protected within the sight housing. If a fiber optic rod does become damaged or lost, the product description notes that spare rods are included, which is a thoughtful inclusion for long-term usability. The dovetail mount design, when properly installed with sufficient tension from the sight pusher tool, is inherently durable and resistant to loosening under recoil. I haven’t experienced any shift or looseness after numerous range trips and daily carry.

Accessories and Customization Options

The Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights package comes with a surprising amount of value in terms of included items. Crucially, it includes both green and red fiber optic rods. This allows the user to select the color that provides the best visibility for their specific eyes and lighting conditions. Swapping these rods is a simple process, typically involving carefully pushing out the old rod and sliding in the new one. The kit also includes the necessary front sight screw and rear sight set screw, ensuring you have everything needed for installation (though a sight pusher tool is generally required). The inclusion of a blank rear sight rod (likely a small black plastic or metal rod) is also present, offering an option for users who might prefer a blacked-out rear sight, though this would negate the fiber optic benefit of the front sight. While these sights themselves are not directly “customizable” in the way some other firearm components are (like changing grips or triggers), the ability to choose your front sight color and the robust materials make them a highly customizable experience for the shooter. They integrate seamlessly with Glock pistols, and the tall profile is specifically designed for optimal co-witnessing with popular micro red dot sights like the RMRcc.

Pros and Cons of Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights

Who Should Buy Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights?

These Angry Bear Arms Glock Bear Bones 42/43/43X/48 Tall Profile Small Frame Fiber Optic Pistol Sights are an excellent choice for Glock owners, specifically those with the Glock 42, 43, 43X, or 48, who are looking to upgrade from their factory sights. They are particularly well-suited for concealed carriers who value a snag-free draw and improved target acquisition. Shooters who have upgraded their Glock MOS models with red dot sights will find the tall profile invaluable for ensuring a reliable iron sight co-witness. They are also a fantastic option for defensive handgun trainers or responsible gun owners who frequently train at the range and want a more robust and visible sighting system. The DIY gun enthusiast comfortable with basic sight installation will appreciate the straightforward fitment.

However, individuals who require sights that function in absolute darkness without any external light source might need to consider tritium night sights as a primary or supplementary option. Those who prioritize a perfectly flush rear sight fitment with no overhang whatsoever might find the minor protrusion of the rear sight base a point of contention. For users who are not comfortable with sight installation tools like a sight pusher, professional installation might be necessary, though the sights themselves are designed for standard Glock dovetails. Recommended accessories would include a quality sight pusher tool for installation, and potentially a lightweight solvent for cleaning the fiber optic rod if it becomes smudged.
