Vector Optics Frenzy 1x20x28 6 MOA Red Dot Sight w/Extra-Large Window, Auto Shut-Down, Fit for Pistol Cut, SCRD-40

This is a great optic from a company with absolutely stellar customer service. I have it mounted on my service pistol, a Gen5 Glock 19MOS. I love the massive lense. I previously had another smaller optic mounted and I must say that I like this one much better. The larger lense makes the red dot come right up at eye level with ease every time.I use +p+ ammo and it has stood up to that recoil with no shift of zero whatsoever. The red dot is very bright, and on the highest setting there is no doubt that you will be able to clearly see that dot even on the sunniest of days. I did look at the dot through the two night vision modes. They are barely visible in pitch dark but through a Gen2 monocular they are perfect.I wanted to state that if the red dot is not clear you probably have an astigmatism. This is often the case when people.blame the optic. I did have a small issue with Amazon sending me a used optic instead of a new one. The great people at Vector quickly mailed me a brand new optic free of charge. They have fantastic customer service.I carry my pistol with this optic mounted daily on the job and I trust it. Purchase with the utmost confidence.

Very easy enough to install and setup on top of my Vortex Spitfire. I zeroed it at 15 yards for CQB. It holds zero after 200 rounds in the range. I will definitely buy it again. I got a lot of compliments on the first day I took it to the range.

Optic works fine, I made this purchase after I broke my RDS and need one in a hurry for a PRS competition. This RDS was twice the price as my last and it does not come with a battery. RDS works as advertised, the protective cover fits loosely and falls off easily. I’m sure this will get lost in no time. Another draw back is you have to remove the optic each time you need to replace the battery. I’ll go back to my Tasco RDS as it was a better design, quality and at a cheaper price.

This is a good general purpose sight. I mounted it on my 20 gague Mossburg and it fit like it was made for it. There is one thing you need to be aware of: this sight does NOT come with a battery installed or even included. Make sure to have, or order, a Cr 2032 battery when you order the sight. I will update this review after I've shot a box or two of shells.

I put this on a Ruger MKIII 22/45.Goods: Fairly easy to mount. Held zero, albeit it's just a .22. Fairly tightly manufactured from the factoryCould go either way: On/off is always a sore point with any reflex sight. This turns on to the last setting. Some of these have auto-adjust, though mine didn't. Buttons are on either side. No shake-awake.Bad: Another device that requires three wrenches to mount, put a battery in, and sight in. Wish somebody would take a page out of Spyderco/Trijicon's book and just use hardware that can be turned with a penny/quarter/knurled knob.For my use case, it's fine. I don't know if it's trust this with a PCC or something heftier. Adequate for range use.

Vortex has stood the test of time. There are many optics that are out there that are just as good, or maybe even better because of features and different styles that are relevant, etc. This one was perfect for my needs. This fit on a Canik Mete SFX, and I did not have to remove the rear sight, which was very important to me. Attached on perfectly, and did not have to adjust the zero when it came out of the box. Still very much quality made, and I took it to the range and shot 250 rounds no problems. Didn’t bounce, go out to zero, and operated flawlessly. Very happy with the purchase. Came on time, and assembly was less than 15 minutes to put together. Good luck!

Just like the header says this does not have the footprint for rmr. They don't say this anywhere in the production description, all they say is "it's vector foot print" which doesn't really help. and now I have to spend time and money making a return.... So if you're buying this to be used as a red dot for your pistol shop elsewhere... Waste of my time.

Purchased this optic since I needed a bigger read dot to replace my Vortex Venom. Since this has the same footprint, I decided to take a chance and was surprised on its accuracy. Shot over 1000 rounds in a USPSA match and has not lost its zero.
