  • MULTI-RETICLE SYSTEM - This Holosun sight is equipped with MRS to let you select a fast sight picture for shorter distances with a 32 MOA circle with a 2 MOA dot; The large circle allows for a hold-over reference and helps guide your eye to the 2 MOA dot; Either the large ring or dot can be deactivated leaving 2MOA Dot Only or 32MOA Circle Only
  • SHAKE AWAKE TECHNOLOGY - Extends battery life by deactivating the optic's LED while not in use; Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred; The slightest touch of the optic instantly reactivates the LED so your Holosun reflex sight for pistol is ready when needed
  • SOLAR FAILSAFE - If your battery fails, this red dot sight for pistol has a backup power source when natural or artificial light is available; Solar Failsafe is activated while in Auto Mode where reticle intensity is automatically adjusted: in brighter conditions, you have a brighter reticle and in lower-light conditions, the reticle will step down in intensity to match any lighting conditions

Description

The Holosun HE508T-GR-X2 Green Dot Sight is an open reflex optical sight that provides a large field of view paired with useful features that will help you stay on target while greatly reducing target acquisition time. The X2 optics offer upgraded features such as a Lock Mode that prevents unintentional button presses while the optic is holstered and a side access battery tray, which allows the operator to change the battery. Holosun manufactured this product from light yet rugged titanium and added a multicoated lens that provides a bright, crisp sight picture. The Holosun HE508T-GR-X2 Green Dot Sight uses both Solar Failsafe technology and a high capacity lithium battery to power the optic, ensuring you'll always have a reliable point of aim in the field. These optics are designed with Shake Awake technology that senses motion to power the sight on and off and last setting recall ensures you don't lose your customized options once the unit powers down. This model offers up to 50,000 hours of battery life. Multi-Reticle System (MRS) gives the option of a 2MOA dot only, 32MOA ring only or ring with dot reticle. All versions are projected from the same LED, so no re-zeroing is needed when changing reticles. Enhance your shooting skills and create a better experience at the range with a Holosun HE508T-GR-X2 Green Dot Sight. In the box: HE508T-GR-X2 Elite Titanium Green Dot Sight, coin battery CR1632, T10L key, lens cloth, and user manual.

Perfect!

Behaves just like a holosun should. Titanium build quality and lightweight makes this a top choice for me. Battery life is solid, size is good. I mounted it onto my Glock 30S in .45 ACP (kinda wider frame) and it fits perfectly. I also mounted it on my FNX-45 Tactical and it was a charm, so it’s highly versatile for larger caliber pistols. I could see this be a slightly large for smaller caliber slides, but nonetheless this is perfect. Target acquisition is top notch too, that window is big enough to sight in. Mounting was easy too. I’ll choose this over expensive Trijicons anyday! ... show more

Good and Tough

Honestly this is a great green dot for a pistol and even a rifle i have ran it on both, this has been my main dot for p226 for ahwile now and I gotta say its extremely tough, my only complaint is the glass clarity, it seems to scratch easy. Other than that its a straight workhorse.

Great sight for the money
Size: 0.63x0.91 Color: Red 2 MOA Dot & 32 MOA Circle (HE508T-RD...
I'll admit, I'm a Trijicon guy. I've carried Trijicon's in IRQ and AFG and firmly believe in their durability, accuracy and own many of the RMR sights. That being said, I decided to try the Holosun based on the positive reviews and the price. So far, I am super impressed with this sight. There are few features I like over the Trijicon RM7. First, I like the "shake awake" feature. Second, the battery location makes changing the battery a breeze and doesn't involve a special tool that gets to close to the optics glass. Third, the solar panel on the top of the sight is a nice touch and helps save battery life (not that its a big concern, but still a nice feature). I have this sight mounted on a Glock G45 MOS, which I carry daily and routinely gets banged around in my rucksack. I have nearly 1000 rounds though it and the Holosun has not lost its zero. I like this sight so much I just ordered another one. Highly recommended! ... show more

I love it. I put it on a pistol caliber carbine for USPSA competition. The large 32 MOA circle makes target acquisition fast. I'm happy with my choice of a green dot.

Best handgun optic for the money.
Size: 0.63x0.91 Color: Green 2 MOA Dot & 32 MOA Circle (HE508T-...
Holosun seems to always be hitting it out of the park. This HE508T-GR X2 Green Circle Dot, Solar Titanium is no different. I mounted it on my Staccato P Dou and man what a combination. Due to having astigmatism and eye surgery I went with the green dot instead of red. compared to my other optics with red dots the green seems to be more crisp to my eye. So if you have similar issues it may be worth going with green rather than red. It offers 3 different recticels depending on you're preference. small 2 MOA dot, a 32 MOA circle, or a combination of the two. I was originally hesitant to use the combination of 2 MOA doe with 32 MOA cross hair circle, but it has slowly grown on me. I would recommend atleast trying both to see what you prefer. The build construction is solid, after mounting I needed to hardly make any adjustment at the range to get zero. The auto light adjustment works well and is very nice for being able to see a crisp dot throughout the day, in doors and out. While this optic has solar panels along the top those are more of a supplemental/emergency power source and it still requires a CR 1632 battery. The battery tray being side access however mean you do not need to remove the optic to change the battery which is a huge plus. Overall a fantastic optic for EDC and duty use. ... show more

Better than the RMR
Size: 0.63x0.91 Color: Red 2 MOA Dot & 32 MOA Circle (HE508T-RD...
Fantastic deal for the money and a proper duty rated optic. Trijicon has long leaned on the fact that they have military contracts and have used this as a crutch for those who love the term “military grade” but don’t actually understand what that means. Considering features, the trijicon RMR is so bare bones that it could be considered archaic at this point. You have to remove the optic and re-zero to change the battery, the bottom of the optic is open to the elements and without a sealing plate the battery just grounds on the frame of the optic and thus was part of the reason it had issues with flicking early on. It only has one reticle and it isn’t great for those with astigmatism. The model with a 3.25 MOA dot looks more like a 8 MOA star to me with my moderate astigmatism. And the optic doesn’t have a solar failsafe or auto adjust brightness. The holosun, on the other hand, has years longer battery life, a solar failsafe, auto adjust brightness with a manual lockout, the batter changes out of the side through a trap door with one flat head screw, the optic is waterproof and sealed, it has the same footprint as the RMR so slide comparability is there and it’s cheaper. It’s literally a no brainer. Trijicon fails to adapt to the times and can no longer lean on its name now that holosun has improved their design for them and made it for lower cost. THE TIME IS NOW OLD MAN ... show more

Magic invisible laser
Size: 0.63x0.91 Color: Green 2 MOA Dot & 32 MOA Circle (HE508T-...
This thing blows my mind. I had never used one before, and when I first tried it, I thought it was off and was confused about how to zero it. But there are little direction heads (left-right, and up-down) - Just know, if your cluster is below the target, adjust it to U (you want your bullets to go Up) and if your cluster is to the right of the target, adjust it to L (you want your bullets to go Left). I'm not looking at it right now (in the gun safe), but one screw head is for up-down and the other is right-left. The directions don't really tell you how to adjust. For accuracy, oh my! I can shoot the eye out of the target at 20 feet, and get close at 30 feet. And I only started shooting 6 months ago. This this dramatically improved my accuracy. It is also so cool, basically using a laser (I just use the dot, not the circle, as the circle doesn't seem to help much), that no one else can see. A magic invisible laser. Sometimes it is hard to find the dot, but that'll come with more practice. What an incredible product. ... show more
