Most Helpful Positive Review Well built; but you have to figure out the per click MOA and BDC Drum values for your gun.
I bought 6 of these. All required the elevation index to be reset (1.5mm hex key required). 3 would barely bottom out at 6/3 but not fully. 3 bottomed out 1 click away from reaching 6/3. In my case, I adjusted the index to allow me to go 6 clicks below 6/3 for a 200 yard small peep site index. The...

Most Helpful Negative Review Large gaps and doesn't align with leapers UTG front sight
I purchased this rear sight and the front sight that it is designed to work with which I reviewed separately. I had more of an issue with the front sight but I'm not thrilled with the rear either. There is a large gap between the front of the aperture base and the mounting base, and the aperture bas...

Slim Rear Sight is Solid

by Jordan, Verified Owner from AK, United States Written on May 25, 2025
The UTG Slim Rear Sight is a lightweight, low-profile backup sight perfect for AR-15 users. Made from durable aircraft-grade aluminum, it mounts securely to Picatinny rails and offers precise windage and elevation adjustments. The dual aperture design works well for both close and long-range shooting.

A solid, budget-friendly rear sight that’s ideal for backup or range use.
Rating: 4.5/5
Pros:
  • Compact and lightweight Easy to install Accurate adjustments Great value for the price
Cons:
  • Cons: Not as rugged as premium options Small profile may be harder to use with gloves
Would recommend: Yes

Good quality.

by Hi I am a parttimetinkerer, Verified Owner from MT, United States Written on April 15, 2025
Much like service related pieces recommend, the adjustments match 3/6 sites the military uses made in Taiwan so the price is right now, nice representation of the Taiwanese peoples handi-work.
Pros:
  • price ergonomics aesthetic use
Cons:
  • stiff dials if thats really a con.
Best Used for:
  • an ar15 rifle with a front site post F gas block

A2 style rear sights are the best

by David Clark, Verified Owner from IN, United States Written on March 28, 2025
Leapers UTG makes (or imports) some good stuff. This sight is made in Taiwan but is made as well as any A2 carry handle rear sight I have used. I like that it attaches solidly to the upper receiver with a torx screw and locktite instead of a bulky knob. It’s holding zero on my suppressed 10.5 inch 5.56 upper with an “F” marked FSB.
Pros:
  • Quality
  • cost
  • form
Cons:
  • None
Would recommend: Yes

Exactly as advertised

by LeafOfNew, Verified Owner from GA, United States Written on October 13, 2024
Well made . Works great. Easy adjustments. For those that need all the top rail space they can get , this takes the place of a carry handle.

Great rear sight!

by Jack, Verified Owner from FL, United States Written on September 27, 2024
The rear sight is really solid for the price and quality and aesthetically pleasing on the eyes on any AR15 rifle. I highly recommend it to anyone that wants a good quality backup rearsight that is not a flip up rear sight.
