Key Features Of Holosun 508t

1. Solar Failsafe technology

I can’t stress enough the importance of having a reliable power source for your optics. The Solar Failsafe technology in the HE508T-X2 is an exceptional feature that addresses this concern.

The integrated solar panel serves as an auxiliary power source, ensuring the sight remains operational even when the battery is low or in low-light conditions.

This feature provides confidence during extended shooting sessions or in situations where battery replacement might be challenging. It’s a game-changer for shooters who need consistent, dependable performance from their sights.

2. Shake Awake technology

Battery conservation is a crucial aspect of any red dot sight, and the Shake Awake technology in the HE508T-X2 is a testament to Holosun’s commitment to providing intelligent solutions.

This technology keeps the sight dormant when not in use, activating it only upon sensing movement. No more manual on/off switches or worrying about battery drain; the sight is always ready when you need it.

I found the Shake Awake feature to be very convenient and much appreciated. I appreciate this feature as it saves valuable time and ensures my sight is ready for action.

3. Multi-Reticle System (MRS)

The MRS on the HE508T-X2 is a valuable feature for shooters who want versatility and adaptability in their red dot sight. The ability to switch between a 2 MOA dot, a 32 MOA circle, or a combination of both caters to various shooting scenarios and personal preferences.

The 2 MOA dot is perfect for precision long-range shots, while the 32 MOA circle aids in rapid target acquisition in close-quarters situations. The HE508T-X2’s MRS offers flexibility that many shooters, including myself, find indispensable.

I really love this feature as it allowed me to customize my experience and get the most out of the optic.

4. Titanium housing

As a professional shooter, I need my gear to be tough and reliable, which is why the CNC-machined titanium housing on the HE508T-X2 is so impressive. Titanium offers lightweight properties and exceptional strength, ensuring the sight can withstand impact, shock, and harsh environmental conditions.

The HE508T-X2’s rugged construction instills confidence, even during heavy use or exposure to harsh elements. It’s a top choice for those who demand high-performance gear.

5. Side-mounted battery tray

The side-mounted battery tray on the HE508T-X2 is a thoughtful design feature that simplifies the battery replacement process. It allows you to change the battery without removing the sight from your firearm, saving time and eliminating the need for re-zeroing.

This feature helps maintain zero and minimize downtime during battery replacement. The compatibility with the widely available CR2032 battery further adds to the convenience, making it easy to find replacements when needed.

6. Parallax-free and unlimited eye relief

The parallax-free performance of the HE508T-X2 ensures that the reticle remains on target, regardless of the shooter’s eye position relative to the sight. This feature enables fast and accurate target acquisition without the need for perfect eye alignment.

Additionally, the unlimited eye relief allows shooters to effectively use the sight with both eyes open, providing a wider field of view and better situational awareness.

These features significantly enhance shooting speed and accuracy, making the HE508T-X2 an excellent choice for a wide range of shooting applications. As a pro shooter, I find these characteristics invaluable in my optics selection.

Performance Review of Holosun HE508T-X2

1. Clarity and brightness

I can attest to the outstanding reticle clarity and brightness of the HE508T-X2. The sight’s high-quality glass and multi-coated lens minimize distortion and deliver sharp, clear images, making target acquisition seamless. With 12 brightness settings, including two night-vision compatible options, adjusting for various lighting conditions is a breeze.

I found the HE508T-X2 to perform consistently well in both bright daylight and low-light situations, providing optimal visibility for accurate shooting.

2. The adjustability of windage and elevation

The HE508T-X2 comes with intuitive, tactile windage and elevation adjustments, simplifying the zeroing process. With a 1 MOA per click adjustment, you can precisely fine-tune the sight’s alignment.

During my testing, I found the adjustments to be consistent and accurate, ensuring my shots were on target. Moreover, the sight maintains its zero remarkably well, even after heavy use and recoil.

3. Battery life and performance

If you ask me about my experience with battery life, I’d say it exceeded my expectations. The HE508T-X2 comes with Holosun’s innovative Shake Awake technology, which senses motion to switch on or off based on user activity. This feature conserves battery power and enhances its performance in a range of light conditions.

I’ve used the sight for extended periods of time, and I still haven’t had to replace the battery. With an estimated runtime of up to 50,000 hours (that’s over 5 years!), you can be assured of reliable performance throughout your shooting sessions.

4. Durability and reliability

The robust CNC machined titanium housing of the HE508T-X2 ensures its durability and reliability.

During my hands-on testing, I Dropped the sight multiple times and even dunked it in a bucket of water, yet there were no signs of wear or damage. Its rugged construction instills confidence, even during heavy use or exposure to harsh elements. It’s a top choice for those who demand high-performance gear.

It is also IP67-rated for water resistance, meaning it can be submerged in water up to 1 meter deep for 30 minutes without any adverse effects.

I value the ruggedness and reliability of the HE508T-X2, as it consistently performs under diverse conditions and endures the demands of the shooting world.

5. Mounting and compatibility

The HE508T-X2 is compatible with a wide array of firearms, making it a versatile and valuable addition to any shooter’s arsenal. Easily mountable on popular handgun models, rifles, and shotguns using the included Picatinny/Weaver rail mount, the sight’s low-profile design ensures minimal interference with the firearm’s ergonomics. Additionally, its lightweight construction adds negligible weight to the overall setup.

In my experience, mounting the HE508T-X2 was effortless, and its compatibility with multiple firearms is a significant advantage for shooters seeking a versatile red dot sight.

6. Size & Weight

The Holosun HE508T-X2 features a compact and low-profile design that makes it an ideal choice for shooters who prefer a minimalistic setup. The sight measures 1.78 inches in length, 1.21 inches in width, and 1.08 inches in height. Its compact dimensions ensure that it does not interfere with the ergonomics of the firearm and allows for easy co-witnessing with iron sights.

Weighing in at just 2 ounces (56.7 grams) without the mount, the HE508T-X2 is remarkably lightweight, thanks to its titanium housing. Its low weight ensures that it does not add any significant heft to your firearm, allowing for quicker target acquisition and reduced fatigue during extended shooting sessions.

Compared to other red dot sights on the market, the HE508T-X2 maintains a competitive edge in terms of weight, making it an attractive option for shooters who value a lightweight setup.

Alternatives Of Holosun 508T

1. Holosun HS507C-X2

The Holosun HS507C-X2 is another popular red dot sight from Holosun, sharing many features with the HE508T-X2. Both sights have the Solar Failsafe technology, Shake Awake technology, and Multi-Reticle System.

However, the HS507C-X2 has an aluminum housing instead of the titanium housing found on the HE508T-X2. This difference makes the HS507C-X2 slightly lighter but potentially less durable than the HE508T-X2.

See the detailed comparison of Holosun 507c and 508t.

2. Trijicon RMR

The Trijicon RMR (Ruggedized Miniature Reflex) sight is a well-known alternative to the Holosun HE508T-X2. The RMR is renowned for its durability and reliability, featuring a forged aluminum housing that can withstand harsh conditions.

It offers a single 3.25 MOA dot reticle and has an auto-adjusting brightness feature, though manual adjustments are also available. One downside of the RMR is its battery placement, requiring dismounting of the sight for battery replacement, unlike the side-mounted battery tray of the HE508T-X2.

Additionally, the RMR typically comes at a higher price point than the HE508T-X2.

See the detailed comparison of Holosun 508t Vs RMR.

3. Holosun HE509T

The Holosun HE509T is a more recent addition to Holosun’s lineup of red dot sights. Like the HE508T-X2, the HE509T features a CNC machined titanium housing, Solar Failsafe technology, Shake Awake technology, and a Multi-Reticle System.

However, the HE509T has a fully enclosed design, which provides added protection to the lens from dirt, debris, and other environmental factors. This feature makes it an attractive option for those who require added durability and protection in harsh conditions.

The HE509T also has a slightly different battery compartment design, requiring the removal of a small cover rather than a side-mounted tray.
