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.

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.

  • Best handgun optic for the money.

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

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 am a newbie when it comes to red dot sights-so least take that into account. I wear a no line bifocal so sometimes seeing my iron sights is problematic and definitely not enjoyable. As a gun owner I take my responsibility seriously, so knowing I can aim effectively at my target and hit what I'm aiming for is of vital importance. On to the sight. First, it arrived safely and we'll protected in the manufacturer's packaging. It included the sight in a plastic box with dense foam, a cleaning cloth, and an adjustment tool. This tool is for adjusting a mounted sight, not for installation. You will need a special torque wrench, loc tight blue, and bit that is not included. Installation was pretty straight forward once I found the properly sized bit. It was my first time installing a sight and it went smoothly. I installed it on my S&W m&p 2.0 metal and I don't find it to be unmanageable in size or form factor. I personally like the aesthetic. Sighting in at the range was also easy. As an Olympic recurve archer, the trial and error of adjusting the sight was a similar process to what I was familiar with, just a slightly different format. For me it took less than a full magazine to be all in the 10 ring - and so far everything has stayed in place and hasn't needed readjusting. One thing I did notice is that the red dot is big. I mean, it is exactly the size advertised - but when you move from 7-10 yards to 25 yards the dot will cover most of the 10 circle on the target. ... show more

Once mounted, Zero was Spot on requiring no adjustment at 10 yards. Fit my Trijicon milled G17 perfectly. Ran it with the outer circle w center green dot. The additional outer ring allowed for rapid acquisition and accurate rounds on target. So far, very impressed with approximately 150 rds down range. Quality and features along w the lower price may make this a better choice over the Trijicon RMR. Time will tell w this triple RMR owner. ... show more
