Bushnell AR Optics Advance Reflex Sight Review

How I Used the Bushnell AR Optics Advance Reflex Sight and What I Found

For years, I’ve been piecing together a rather eclectic collection of gear, spanning everything from delicate laboratory instruments to robust tools for workshop mayhem and reliable equipment for the unforgiving outdoors. My search for a compact, dependable red dot optic for my burgeoning pistol collection led me to the Bushnell AR Optics Advance Reflex Sight. It promised a small footprint and robust build, qualities I desperately needed for a specific pistol build I was working on. The need was for a quick-acquisition sight that wouldn’t add significant bulk or weight, something that could handle recoil and still offer a clear aiming point in various conditions.

Prior to settling on this particular Bushnell optic, I’d spent time looking at several micro-red dots, including options from Sig Sauer and Swampfox, but their price points, or in some cases, bulkier profiles, made me pause. The Bushnell AR Optics Advance Reflex Sight, however, struck me as a potential sweet spot between affordability and functionality. Out of the box, my initial impression was one of pleasant surprise; the unit felt solid, well-machined, and surprisingly lightweight. The anodized finish looked durable, and the glass seemed clear with no discernible tint. It wasn’t the most premium-feeling optic I’d ever handled, but for its intended purpose and price, it felt more than adequate.

There was an immediate sense of relief mixed with a healthy dose of curiosity. Would this compact sight live up to its claims, especially given its rather modest price point compared to some of its competitors? Only time and a steady diet of live fire would tell.

Real-World Testing: Putting Bushnell AR Optics Advance Reflex Sight to the Test

My testing regimen for any piece of equipment is rigorous, and the Bushnell AR Optics Advance Reflex Sight was no exception. I’ve integrated it into a few different setups, pushing it beyond its likely intended use case to truly understand its limits and capabilities.

First Use Experience

My initial testing grounds were the familiar confines of my local indoor range, and crucially, my personal range setup in the backyard. I mounted the optic on a Glock 34, a pistol known for its longer sight radius but still a prime candidate for a red dot. The installation was straightforward, especially with its compatibility with Glock Mount Plate #1, requiring minimal fuss. The brightness adjustment was intuitive, easily cycling through its 12 settings.

Conditions varied from dim indoor lighting to bright, midday sun. In all these scenarios, the 5 MOA dot proved to be a significant advantage. It was bright enough to be seen against a brightly lit backdrop without washing out, and at the lower settings, it was equally visible in low light. I noticed immediately that the dot was crisp and well-defined, not fuzzy or blooming, which is a common issue with lesser optics.

One early surprise came during a particularly energetic range session where I was running drills that involved quickly reacquiring targets after rapid fire. The optic held zero admirably, with no discernible shift after several magazines. A minor quirk I noted was the lack of audible clicks for the windage and elevation adjustments. While this allows for infinite adjustability, it means relying on the etched markers for zeroing, which can be a touch less precise than a tactile click. However, the detents felt solid, and the adjustment screws themselves offered positive engagement.

Extended Use & Reliability

Over several months, this micro-red dot has seen more than its fair share of use. It’s been mounted on my Saiga 12 shotgun, enduring the substantial recoil impulse of 12-gauge rounds, including heavy slugs. This is where the shockproof construction truly proved its worth. Despite hundreds of rounds, from light target loads to magnum slugs, the sight has maintained its zero without any drift or issues. I’ve also had it on an AR9 carbine, where its compact size and lightweight nature were invaluable for a build focused on quick handling.

The weatherproof and fogproof claims have also been put to the test. I’ve used it in light rain and humid conditions without any internal fogging or external water ingress affecting performance. The O-ring seals seem to be doing their job effectively, providing confidence when the weather turns foul. Maintenance has been minimal, mostly just a quick wipe-down of the lenses with a microfiber cloth. The side-mounted battery tray is a godsend, allowing for battery swaps without removing the optic, a feature that significantly reduces downtime and hassle.

Compared to some of the budget reflex sights I’ve used in the past, which often fail after a few hundred rounds or succumb to environmental factors, the Bushnell AR Optics Advance Reflex Sight has demonstrated a level of durability and reliability that punches well above its weight class. It’s not a Trijicon RMR, but for its price point, it offers a performance envelope that easily rivals optics costing significantly more.

Breaking Down the Features of Bushnell AR Optics Advance Reflex Sight

The Bushnell AR Optics Advance Reflex Sight is designed to be a compact, no-nonsense aiming solution, and its feature set reflects this philosophy.

Specifications

The core specifications highlight the compact nature and intended application of this optic. It boasts a 1x magnification, making it ideal for close-quarters engagements where speed is paramount. The objective lens diameter of 44 mm is measured across the housing, and it’s important to note that the actual lens aperture is considerably smaller, contributing to its reduced size.

The reticle is a single, bright 5 MOA red dot. This size is a sweet spot for many users, offering sufficient visibility in daylight without being overly large at closer distances. It features 12 brightness settings, providing ample adjustment for various lighting conditions, from dawn to dusk. Eye relief is, as expected for a reflex sight, unlimited, meaning you can acquire the target quickly without precise head positioning.

Adjustment for windage and elevation is 1 MOA per click, although as noted, these are not audible clicks but rather detents. The parallax is set at 50 yards, meaning the reticle appears to stay fixed regardless of your eye position when sighted in at that distance. The optics are multi-coated for improved light transmission and reduced glare.

Powering the sight is a common CR2032 battery. Bushnell claims an impressive battery life of 50,000 hours on the lowest setting, a figure that, while often theoretical, suggests excellent efficiency. The unit is fog resistant and has an IPX-7 water resistance level, meaning it can withstand submersion up to 1 meter for 30 minutes. Its length is 44 mm, and it weighs a mere 62 grams, making it incredibly lightweight.

The mount type is listed as Weaver, but it comes with adapters for both Picatinny and Weaver rails, offering broad compatibility. It’s also specifically compatible with Glock Mount Plate #1, a crucial detail for pistol shooters looking for a direct slide-mount solution.

Performance & Functionality

In terms of its primary job – making you faster on target – the Bushnell AR Optics Advance Reflex Sight performs exceptionally well. The 5 MOA red dot is its standout feature, offering a bright, clear aiming point that is easy to pick up, even under pressure. This is a significant improvement over smaller dots for shooters who struggle with red dot visibility in bright light.

The 12 brightness settings are well-spaced. The lowest settings are perfect for low-light or nighttime use, while the upper settings can cut through direct sunlight effectively. I found the transition between settings to be smooth, and the button controls are easily accessible. The side-mounted battery tray is a game-changer for convenience, allowing for quick swaps without disrupting the optic’s zero.

The main functional limitation, as previously mentioned, is the lack of tactile click adjustments. While the detents are firm, judging exact MOA adjustments without an audible click can be tricky. This is a trade-off for a more compact and potentially more waterproof design. However, once zeroed, the optic has proven to hold its zero exceptionally well, even under heavy recoil.

Design & Ergonomics

The design is undeniably compact and streamlined. Its 44 mm length and 62-gram weight make it one of the lightest and smallest options in its class, ideal for applications where space and weight are critical. The open emitter design contributes to its low profile. The black, matte finish is non-reflective and feels durable.

Ergonomically, the button placement for brightness adjustment is well-thought-out, allowing for easy manipulation with a thumb or finger. The overall shape is smooth, with no sharp edges that could snag on gear. The glass is clear, and the multi-coated lens minimizes glare and reflections, aiding in target acquisition.

The included Picatinny adapter mount is robust, and when used with the correct plate on a compatible pistol, it creates a solid, integrated platform. The only ergonomic consideration is the adjustment mechanism, where the absence of clicks might be a minor drawback for those accustomed to them.

Durability & Maintenance

The Bushnell AR Optics Advance Reflex Sight appears to be built for hard use. The shockproof construction is evident in its ability to withstand the significant recoil of a Saiga 12 without issue. The waterproof and fogproof ratings are not mere marketing terms; my tests confirmed its resistance to the elements.

Maintenance is straightforward: keep the lenses clean and ensure the battery is fresh. The side-access battery tray simplifies this process immensely, a feature that is often overlooked but is incredibly valuable in the field. Given its construction and my experience, I anticipate this optic will last for a considerable amount of time for most users, especially those not subjecting it to extreme abuse. The primary potential failure point for most red dots is battery failure or a damaged emitter, but the extended battery life and robust housing mitigate these risks.

Accessories and Customization Options

The Bushnell AR Optics Advance Reflex Sight comes with a basic but functional accessory package. It includes the necessary mount for Picatinny and Weaver rails, which is a standard attachment method for many firearms. For specific pistol applications, such as Glock MOS systems, compatibility with Glock Mount Plate #1 is a key selling point and essentially serves as a necessary adapter.

While the sight itself is not highly customizable in terms of reticle options (it’s a fixed 5 MOA red dot), its mounting system allows for significant versatility. It can be mounted on virtually any platform with a Picatinny or Weaver rail, from tactical shotguns and carbines to pistol slides via the appropriate adapter plate. The CR2032 battery is readily available and inexpensive, making replacements easy to source.
