[Optical] I ordered and have owned this sight since 4/29/2022 and I have to say I am STILL absolutely blown away by the quality. I mounted it to a Stoeger M3000 Defense semi-auto 12gauge and I have ran every kind of load I can find on the local market. The sight has held up through mud and water being splashed onto it when my shotgun was mounted to the front of my 4 wheeler while tending to my property, It's held zero the entire time and is extremely accurate with slugs even out of my short 18inch barrel Stoeger. I thought the recoil of a full power 3inch slug out of an 18inch barrel was going to cause it to loose zero but It's been 2 years, hundreds of slugs through it and its still holding zero. It was my first entry to red dot sights and I have to say, I loved it the day I mounted and sighted it in and I still love it 2 years later! For the price and it being Bushnell you cant go wrong. I haven't had a single issue, I haven't even had to change the battery yet! It was the perfect addition to my semi-auto shotgun that I never knew I needed until I mounted it. I highly recommend it!

[Optical] I really like the ease of adjustment for sighting in. The one feature that I was really sold on was where the battery was located and the how easy it was to replace.

[0.325 lb] Great when using a telephoto for flying bird photography!

[Optical] This red dot sight mounts easily and is very easy to use. I like the large diameter lens that allows you to get on target quickly. The adjustments are easy to make. I use this for target shooting and would use it for hunting too. You could buy a better sight for a lot more money, but this one is well worth what it cost.

[0.325 lb] This little sight is awesome!! It's easy to sight in and is accurate. I bought one for my .44 mag marlin for deer hunting and another for my AR .22 M&P. Love them both!!

[Optical] I like to photograph birds in flight with telephoto lenses. I use the Canon RF 100-500mm w RF 1.4X Extender and a Canon RF 600mm F4 with either the RF 1.4X or 2X extenders. Due to the narrow angle of view with telephoto lenses, it is difficult to locate birds in flight. The Olympus Dot Sight mounts to the camera hot shoe and after distance calibration; makes tracking birds easy. With the 600mm F4 you will have to put a hot shoe extender on first to elevate the sight above the lens profile. This is highly invaluable for either birds or other fact moving subjects when tracking with a telephoto lens.

[0.325 lb] The benefits outweigh the negatives. It must be calibrated every time with what ever lens you are using. This is simple enough to do, and unless you do it there is no guarantee you will be aiming your lens in the right direction. Also: if you where a brimmed hat, it is likely it'll get bumped by the brim when you use your view-finder. I was able to overcome this by mounting the dot-sight on a
SmallRig Half Camera Cage with a Tilta Cold Shoe Receiver Adapter with Locking Pin in the cage's forward mounting position.

[0.325 lb] This dot sight is great for BIF (Birds In Flight), allowing you to track the bird thru the dot sight using your peripheral vision while keeping your telephoto lens completely zoomed in. It works on ANY brand of camera and only requires a cold shoe. It does need to be calibrated every time you use it, but the results are well worth the time.

[Optical] Bought this for my Mossberg. Easy to use. I’m an LEO in Arizona.

[0.325 lb] Bushnell products are quality with a reasonable price. I have used their red dots on multiple firearms over the years with NO issues.
