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...

1st rate sight for the AR15

by WILLIAM, Verified Owner from NC, United States Written on September 8, 2026

I already had five of these sights and I have been using them for years and I needed another one and I bought this sight along with a matching front sight from Optics Planet. There are more and less expensive sights available but this sight is the best value. This sight mounts securely and is absolutely dependable. Operation and sight adjustments are familiar to anyone with experience with the AR15 type rifles. This sight might work on other types of rifles, just be sure the front and rear sight height is a close match.

Pros:

The best overall value.
reliable and trustworthy
familiar installation and adjustments

Cons:

None

Best Used for:

Any AR15 where iron sights are the preferred option and optics are not needed or wanted.

Just what I was looking for. Solid construction that will take a little abuse and still keep ticking

easy on, easy zero

by T3 Professional Development, Verified Owner from MN, United States Written on December 4, 2025

nice fixed option as opposed to carry handle. Keeps the door open for other options but still looks sharp.

Slim Rear Sight is Solid

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.

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
