Highly recommend holosun 507k x2
Best micro red dot I have ever used. The windage/ elevation has tactile audible clicks for easy precise use. The glass and reticle are crystal clear. I wasted tons of $ on multiple other brands, holosun is leaps and bounds above everything else I've tried. Take it from me, buy once cry once over the $ instead of being like me and wasting time and $ on inferior products.Verified purchase: YesCondition: New

Red dot would not turn on.
I really like Holosun products as a general rule. I have a couple on other pieces that work flawlessly and I really didn't like giving this particular unit such low marks. However, this one came and just didn't work. I couldn't get the red dot to turn on. I put in a new battery and still nothing. I finally had to send it back to Holosun to see if it could be repaired. Maybe I just got the one in a hundred lemons.Verified purchase: YesCondition: New

Holosun 507K green dot
Arrived fast at home and the Holosun green dot is easy to acquire when putting your pistol on target, easy to use and the reticle has three different options to chose from. Awesome price and product highly recommend over the red dot.. A++++Verified purchase: YesCondition: Pre-owned

Perhaps the best red dot on the market!!!
It's hard to believe you can obtain quality such as this at such a low price. I have Holosun optics on at least 5 of my firearms and in each case they have exceeded my expectations. The HS 507K-X2 is special since it's only one of two that I'm aware of that fit the Sig Sauer P363-XL. It was almost too easy to install and you keep thinking, what's missing? The optics are clear and the red dot options are perfect and easy to find when you raise the weapon to firing position. I first adjusted the red dot using the built in standard iron V sight mounted on the optic and after that, there was very little adjustment necessary. The quality of workmanship and materials is top notch and appear made to last a lifetime. Speaking of "lifetime", battery life of 50,000 hours would certainly last a life time of casual shooting and a mighty long time while carrying. If you're looking for a small footprint optic with superior quality, look no further than Holosun and especially this HS 507K-X2. My only criticism would be that Holosun should bring manufacture of these devices to the USA. I'm not in favor of anything made in China, but sometimes you have to compromise and this site is one time it seems prudent.Verified purchase: YesCondition: New

Holosun sight
This is the best sight I have mounted on a pistol! Shake awake is the way to go no fumbling to turn on the sight. It's ready to use when you need it. Better than the other brands that I have but far! Bought a 2nd one right away the one with solar panels for backup. You can't go wrong very well made.Verified purchase: YesCondition: New

Great red dot.
It fits on my Glock 48 MOS and has the brightness adjustments RMSc Shield doesn't. I ordered an in stock Item from Optics Planet and after 3 days it was canceled because I supposedly requested it, which I never did. I tried ordering online from them and they were "processing" it for almost 3 weeks before they canceled it for no given reason. Shady sales practices!Verified purchase: YesCondition: New

Small package and great image quality
Exactly what I was looking for. "Shake awake" feature is great as well as the 32 MOA circle. Mounted it on a 43X MOS using an adapter plate.Verified purchase: YesCondition: New

Holosun 507k
This optic is by far better than the Romeo zero simply because of button placement and standard features, battery compartment, And clarity of site picture, easy to mount includes screws I run a Sig p365XL and love both definitely recommend. Cons I wish it was solar/Battery like the 503c and had auto brightness like the 503c it would be perfect.Verified purchase: YesCondition: New
