Most Helpful Positive Review Best Choice for a Fixed Rear
Recently finished an AR build using a lot of quality components, and the plastic Magpul flip-ups sights I was using as BUIS seemed out of place (good sights though, will save to use on something else). Since I was getting a nice bottom 1/3 co-witness with my EOtech, I decided to go with a fixed iron sights as a backup. These seemed like the best option and they didn't disappoint. Both the rear and front are nice and solid. Windage adjustment is a little bit of a pain, but the same as any other A2 style rear sight. If you need iron sights for your flat-top AR, or need BUIS for an optic that c...

Back to basics

by Gunner257, Verified Owner from SD, United States Written on July 21, 2025
I have been returning to iron sights on some of my ARs. They don’t fog up, they are more robust, they don’t use batteries, and they areless complex than scopes. Daniel Defense makes a nice unit for those wanting to get back to basics.

Possibly the best fixed rear sight out there

by Guy on the couch, Verified Owner from AZ, United States Written on May 4, 2025
Rock solid. Simple. This is the evolution from a tried and tested winner, the A2. It is meant to be a backup, but there’s no reason you couldn’t run this as part of a “primary” iron sight configuration. I grew up on iron sights, tend to prefer them over optics, and know what I can do with them at different distances. That said, I use this on a very basic AR15 meant for CQB. Never liked the price… but opticsplanet helps with that. Nab one today and see what I mean.
Pros:
  • Simple. Solid. Milspec.
Cons:
  • Expensive.
Best Used for:
  • CQB. Backup.

The standard mounting screw

by Gary, Verified Owner from OH, United States Written on February 28, 2025
The mounting screw needs to be replaced with a socket head cap screw to prevent marring when you are mounting the sight.

Daniel defense rear sight

by ml, Verified Owner from CA, United States Written on June 19, 2022
The sight mounted perfectly and is extremely light weight. It feels very durable and lines up with my a2 sight. It costs more than the competition but you can tell that you get what you pay for. It’s a great addition to my mid length lightweight rifle.
Pros:
  • light but solid
Cons:
  • Price $$$
Would recommend: Yes

great sights!

by senecaSteve, Verified Owner from OH, United States Written on December 5, 2021
I would buy this rear iron sight a million times over just not from Optics Planet because they are way too expensive here. My advice is if you’re really wanting this particular sight go to Daniel Defense website and get it there for sooooooo much cheaper. Your welcome!
Pros:
  • They are battle proven.
Cons:
  • None
Would recommend: Yes

Great fixed sight

by Rear sight, from ID, United States Written on July 12, 2021
This product is just what I was looking for. Easy to adjust, accurate. Can't go wrong with this one, would buy again. Experience with opticsplanet was great as well. The item shipped quickly and received without any issues.

Simple, Rugged, & Reliable

by Kristopher Swift, Verified Owner from TX, United States Written on May 13, 2021
I use this sight on every AR I own for three reasons. First, I don't need to carry or find a star bit or an Allen key to remove or adjust it, just a simple flat screwdriver. Second, It's set and forget. Once it is sighted in I don't have to worry about accidentally bumping a wheel or turning a knob, yet it's easily adjusted with the tip of a round. Once it's set, it's set. Third, it doesn't have sharp edges to tear up your hand when you have to manipulate your charging handle. This is the perfect companion to the Daniel Defense front sight, I recommend them both.
Pros:
  • light weight
  • rugged
  • reliable
  • Simple
Cons:
  • Nothing yet

Solid iron sight

by tsw, Verified Owner from CO, United States Written on March 9, 2021
Great, heavy-duty iron sight. Tougher that flip ups, but low profile as to not block the window of a co-witnessed optic. Big improvement over A2-based iron sight designs as the A2 elevation adjustment is serious overkill and needlessly complex for backup irons, shooting under ~300yds, or anything that isn't a NRA rifle match.
Best Used for:
  • Backups for carbines/pistols
Would recommend: Yes

best fixed rear sight

by Clyde, Verified Owner from GA, United States Written on March 9, 2021
This is one of the best rear sights on the market by a reputable manufacture. The rear aperture flips easy but it still stiff enough to stay in place under recoil of even a 308. Also co witnesses with most optics.
Pros:
  • Fast on target
Cons:
  • None
Best Used for:
  • Home defense, LEO/Military use
Would recommend: Yes
