To expand compatibility, MOS-to-RMSc and RMR-to-RMSc adapter plates are included, allowing the optic to fit even more handgun platforms

Description

We specialize in optics and display technology. We build gear that professionals and dedicated enthusiasts can depend on in every environment . ZEROHAWK is more than a brand — it’s a commitment to excellence, built for elite professionals and for anyone striving to push their limits with gear that will never hold them back and find their focus. How do I know if the EM1 will fit my setup? The EM1 fits RMSc-cut, optics-ready slides and includes RMR-to-RMSc and MOS-to-RMSc adapter plates. Check our compatibility chart before ordering. If your model isn't listed, verify your slide's mounting footprint. I have astigmatism and the reticle looks blurry or starburst-shaped. Is it defective? Astigmatism can make a red dot appear blurry, distorted, or starburst-shaped. Try viewing the reticle through a pinhole or take a photo of it with your phone camera. If the reticle appears clear in the photo, the optic is likely functioning normally. How do I know whether a red or green dot is right for me? Green dots may appear brighter and easier to see in daylight, while some shooters with astigmatism may find red dots clearer. Since everyone’s vision is different, choose the color that looks clearest and most comfortable to your eyes. What are the benefits of an aspherical lens? The aspherical lens design delivers exceptional optical clarity with minimal distortion and parallax-free performance for a clear, natural view. What happens when the battery runs low? When the battery voltage drops below 2.5V, the reticle will flash 5 times at startup as a reminder to replace the battery.

Great buy for a great sight!
Color: Black Reticle type: Red 2 MOA Dot & 32 MOA Circle
Im very impressed with is enclosed sight, the reticle is clean and crisp without artifacts or distortion. The windage/elevation adjustments are positive and track as they should. It comes with enough mounting screws to fit it without issue on whatever your mounting it on. It sits low on my slide and co-witnesses well with extra tall sights. The battery tray is easy to get too without removing from the slide/mount when you need to replace the battery. The brightness buttons are easily adjusted and sit flush with the housing. Overall im very happy with this sight and will be picking another up shortly. ... show more

Solid, Durable, Sight.
Color: FDE Reticle type: Red 2 MOA Dot & 32 MOA Circle
Quality sight, hold zero well. Would recommend using red loctite. The shake wake has been very good and all features have been perfect. It has many features for its price point. Very durable, actually dropped it hard on to pavement from stomach height on pavement. Fell right on the corner of the sight, assumed it was toast. Not only was the sight fine but the zero held the exact same. Was very surprised. 9.5/10 good buy ... show more

Excellent choice
Color: FDE Reticle type: Red 2 MOA Dot & 32 MOA Circle
Outstanding. Fit the RMSc footprint perfectly. Comes with about 6 sets of screws to fit whatever the thread cut is. Adaptor plates as well. Packaging is 2nd to none. Seems to hold zero well (200 rounds down range). Would order again.

Incorrect installation of battery deadlines gun optic
Color: Black Reticle type: Green 6 MOA Dot
Total trash stay away, if you put the battery in upside down, the "captive" screw comes back out, the tray does not, friction fit for water tightness instead of an o-ring. No engineering for in case you put a coin shaped battery in wrong. Your sight out of the box won't work, and the aluminum will snap any small steal flat head screw driver small enough to even maybe fin inside the tiny gap so you can try and pry the tray back out to not have wasted your money. And then you'll stab yourself in the process of trying to save your money on such a poorly thought out investment. If you can't get the battery tray right for a gun optic don't even bother. Would rate 0 stars if it was an option. STAY AWAY ... show more

Great optic.
Color: FDE Reticle type: Red 2 MOA Dot & 32 MOA Circle
I ended up getting this optic and a little bit of the finish flaked off. I emailed the company and showed them a picture and they did not hesitate to send me a brand new one and let me keep this one as well. It is an outstanding optic especially for the price. And their customer service was top notch. After email I received the new optic in two days. Just unreal ... show more

Great value
Color: Black Reticle type: Red 2 MOA Dot & 32 MOA Circle
As long as this stays as a BUDGET option, this is a great value enclosed optic. Not having 'tested' it yet (durability or keeping zero yet), but just sighting it in and mounting it, so far very good. Machining, accessories (screw set, plates, battery) have been top notch. The enclosed optic seems decent, and the optic window is clear. Not the largest which is fine especially for a CCW/and RMSc footprint. It's meant for a compact/micro. Works and fits perfect on your Hellcat, P365, MC9s, Echelon, etc. Really good fit and finish. Hopefully the durability and ability to hold zero holds true. Will update once I go to the range. Have it mounted on a 10mm compact and this will test how 'durable' and 'can it hold' we'll find out. The dials to adjust the windage and elevation is easy. The mounting with included plates (plastic) was easy. Screw set is comprehensive and EXCELLENT. Thank you! ... show more

Get it if you want a cheap dot - it’s great
Color: Black Reticle type: Red 2 MOA Dot & 32 MOA Circle
Got this on sale and threw it on my FN502 pistol. Have about 1k rounds down the barrel with this thing mounted and it has been great. For this price, I will gladly purchase more to throw on my fun/range guns. Took a bunch of nasty abuse from a suppressor and wiped clean without scratches. Great product haha ... show more
