Most Helpful Positive Review Old Guy review
I have been target shooting for 72 years. Most of the time with iron sights and lately with scopes on rifles. I had some minor experience in the military but mostly target shoot for pleasure. Just recently one of my sons asked me to try his Sig that had an expensive red dot mounted. I fired a few rounds but because of the recoil I didn’t give it a fair test. Later I decided to investigate further and purchased an Osight SE and mounted it on my PX4 Compact Carry. Mounting and zeroing was fairly easy. Once I got to the range I was very surprised as the results. My honest feeling is “it’s like c...

Home Run Red Dot

by digger dig, Verified Owner from SC, United States Written on September 2, 2026
Osight knocked it out of the park with the SE. Clear, crisp reticle. Enclosed emitter makes glass easy to keep clean. It was easy to zero with tactile adjustment screws. I’ve only put one box of rounds (50) through my Sig Sauer P365-380. I’ll update if my opinion changes. I have Holosun, Sig Sauer, C-More, Viridian, Truglow and Burris red dot sights. The Osight SE is right up there with my Holosun 507. Can’t find a better optic at this price point.
Pros:
  • muliti-reticle, enclosed emitter, price, accurate, side mounted battery tray on a micro red dot
Cons:
  • none so far
Best Used for:
  • CCW, home defense, competitive shooting
Would recommend: Yes

Osight SE Red Dot

by Devin Willinger, Verified Owner from KS, United States Written on August 9, 2026
Worth every penny. Punches way above its price point. Direct fit for my 43x. Small compact closed emitter that performs. Glad that Osight listened to the feedback and is continually launching new products that meet all its consumers needs.

Enclosed - fit well - RMSc footprint - Was Demo but box sealed

by Dave-in-Texarkana, Verified Owner from TX, United States Written on July 28, 2026
I have many Olight/Osight products. This is my fully enclosed emiter. I put it on a CZ P-09 Com and the fit was perfect - it zeroed fine and the brightness adjusted well for in the house and outside on a bright sunny day. it's as advertised. This was suposedly a Demo/Open box, but the box had the plastic still sealed so a fair price too. I'm not sure why my review isn't being accepted when I hit submit??
Pros:
  • Price
  • Quality
  • Fit
Cons:
  • None
Best Used for:
  • RMSc footprint

Best optics at great prices

by Pugamus, Verified Owner from TX, United States Written on July 11, 2026
I’ve always purchased my optics through this site and honest I’ve never had a problem. The returns are rare and the warranties on these are superb. I love finding the demo models at a cheap price. I had many red dots and none of them crapped out yet. Replaced maybe 2 batteries in about 3 years. I have so many optics and they’re still truckin’
Pros:
  • Affordability and ruggedness
Cons:
  • None
Best Used for:
  • CCW & Home Defense
Would recommend: Yes

SE 2MOA DOT& 32MOA CIRCLE RED DO

by NJ2A, Verified Owner from NJ, United States Written on May 21, 2026
I mostly buy Holosun red dots but thought I'd give this a try and NO complaints. It has the enclosed emitter and nice clear glass. I installed it on a Glock G30S after having the slide milled and no overhang, it looks like it was made for it. The only issue I had and the right side 6-32 screw was a bit too long and bottomed out on the extractor internally rendering the extractor inoperable. After finding the problem I was able to grind off enough material from the screw and not damage the threads. The 6-32 left side screw length was fine out of the box but YMMV. I’m giving it Five Stars and would buy again.
Pros:
  • GREAT PRICE
  • Nice looking
  • Great feature, ergonomics, finish, design
Cons:
  • lack of 6-32 screw lenght selection
Best Used for:
  • Range
  • Home defense
Would recommend: Yes

Nice budget option

by Robb C, Verified Owner from MI, United States Written on May 2, 2026
Clear and bright. Mounted easily. easy to zero. This one is on top a Burris 3x prism which is mounted to a S & W Response AR9. My setup is purely a range toy but functions well for both distance and close range steel targets. Looks really cool too!!
Pros:
  • Bright & clear dot
  • Easy to mount & zero.
Cons:
  • wish it was available with green reticle
Would recommend: Yes

Better than the 507K

by Lumpy, Verified Owner from NC, United States Written on April 4, 2026
Put it on my Glock 43XMOS and it needs no adapter, unlike the Holosun. Being a closed mirror, there is a lot less dust on my everyday carry, and it is much easier to clean. I also feel that the window is bigger, allowing me a faster site picture.
