CyeleeCAT G-PRO Green Dot Sight for RMSc/407k/507k Footprint - 3MOA Reflex Sight with Motion Deactivated Standby(Similiar to Shake Awake)

Cyelee is punching well above their weight class with this one. Depending on whether you want a red or green dot you can have a good quality working optic for under $200. I went with the Cat G-Pro for an extra $25 cuz I wanted the green and I'm not dissapointed. Some people are hating because they are made in China but so is Holosun and the fit and finish of Cyelee's stuff seems to be a lot nicer. Highly recomended. The only changes I would make is texture or add knurling to the front of the optic to rack the slide from, delete the lasered cyelee logo above the battery tray its already stamped in the top of the housing we dont need it twice. And include a universal chart somewhere explaining which size screws need to be used with each gun, I had to go digging for that info. Installed on a Glock 43x MOS.

Wonder product, would definitely purchase again. Easy to attach and holds zero perfect

First its important to double check the make and model of your firearm to make sure that this will properly attach. When I ordered it, I thought that my pistol was on the list but when I went to install it, the screw pattern was wrong. Double checked--nope, it was never advertised to fit.On the positive side, the green dot is bright and the battery has lasted well and it works just as well now as when I first opened the box nearly six months ago.

this is much better in every way vs holosun 407k, the window is bigger, the ability to use slide is better, it looks much better, the dot is better....

JUST GET A HOLOSUNI opened my box and was super excited to try it out, I turned it on no problem so far, I go to grab my gun so I could install it and the dot went away. at first, I thought it was user error, but then I messed with it and the light would flicker and then completely fizzled out. I assumed it was may be the battery that I had shipped with so I went out to my local convenience. Store bought a new nice battery and no dot. If you’re looking for an expensive paperweight this is for you! If you want a good budget optic, I advise you look some place else.

This is a nice GREEN dot optic. It has a shake awake function that actually works. You can also turn the optic on and off, or lock it off manually if desired. The optic comes with a nice cover that has an attachment point for a lanyard. The optic is powered by a CR1632 cell. One is provided with the optic, but I'd recommend replacing it with a name brand cell. Battery (cell) life is said to be 50,000 hours, which is about 5.7 years but I'd replace it every year just to be safe. Various mounting screws are provided, as are two two "tools" to adjust the optic and tighten to screws. I'd use my own tools.Included are clear instructions on setup, adjustment, and installation. The manufacturer specifies the mounting screws to be torqued to 15lb/in and to use Locktite 242 on the screw threads. This is a fairly small housing dot sight. However, the dot window is big and the dot can be adjusted to 8 daylight brightnesses, and 2 for night vision. I have night vision but wouldn't use it with a dot so I did not test that as I had no reason to.All in all I am pleased with this optic. I am a long time shooter and have some very expensive glass for my guns. This optic is inexpensive, but not cheap. It is well made and I will now mount it on my carry gun as I trust it. If you're looking for a nice green dot optic with shake awake functionality, this dot may be for you. It's light, bright, and will likely serve you for a long time. If not, it has a lifetime warranty. So yes, I recommend it.

Purchased this green dot sight for my Ruger pistol. Good fit and easy install. Tighten screws all the way so vibration of shooting does not loosen them. Clear image down range. Shuts off automatically and also is 'shake awake'. I found the sight accurate and easy to use/setup. Overall, I'm happy with my purchase.

Right outa the gate Im going to tell you I have no clue what RMSc / 407K / 507K Footprint is or means and chances are neither do you. Im guessing it has something to do with some one some where being able to track you or find you through your weapon that this sight is installed on, like maybe some sort of fancy G.P.S ..... This is also a guess, but Im guessing unless your a member of a seal team or some sort of special opp's unit you like me will have absolutely zero use for the expensive tecknowledgy this green dot sight possess's . The owners manual, instructional pamphlet if you will was not at all helpful in fact it was more less a small fold out that had the oddest explanation of how to zero this green dot sight that Ive ever seen, and I know how to zero what ever Im zeroing that day,they also send in the box whats referred to as a help card which is basically a www.com getinlinehurryup&wait, the sight its self did not come with a mount to adhere it and secure it to a picatinny rail or any other rail. Now Im thinking with all that tecknowledgy this little gem seems to possess why didn't they include a 5$ mount for the sight to be able to be used immediately instead of the customer (me) having to special order it and wait some more or do as I really did & Macgyver it on to one of my many mounts. When its all said and done, its only average, I have red, green dot sights I paid maybe a third of what this costs that I like much better and as far as Im concerned are a better sight., Im sorry but today its a no from me.
