Most Helpful Positive Review Bought for several builds, never had an issue
Honestly, it's exactly what it is. An A1 rear sight. It's a pain to install, pain to adjust, etc. Before you start your build make sure you use copious amounts of gun oil on the upper, this will help you greatly with the install. To be clear, this isn't the fault of the parts. The parts are perfectl...

Most Helpful Negative Review Out of spec parts
I have a Luth AR A1 upper and these parts are out of wildly out of spec. The leaf spring is too tight and therefore I can't turn the windage drum once installed. The leaf spring is so tight that the rear sight doesn't even flip down all the way. Should throw in some extra roll pins for this as we...

Windage Drum Sucks

by Your Mom Says Hi, from FM, United States Written on March 5, 2025
Luth, I usually dig their stuff, but the hole in the windage drum was waaaaaaaaaaay to small for the supplied roll pin. I should have known better. There are numerous others with the same issue. Nothing I could do short of opening up a bit, and I dont have that many Fs to give or that small a bit, so I'll use one from another manufacturer. I suggest you do the same

Leaf spring too large/stiff

by Matt B, from CA, United States Written on September 22, 2021
Leaf spring is too long and stiff to fit in the Luth Ar upper. Barely able to install the sight and windage adjustment is impossible to use due to the excess tension. Now I have to disassemble the sight and find a new leaf spring.

Missing roll pin

by Foolhardy, from CA, United States Written on June 27, 2021
Bought this rear sight kit to complete my stripped upper. Unfortunately the roll pin was missing from the kit. Thankfully I was able to get one from an old trigger guard I had laying around and complete my build. Otherwise everything installed just fine without any problems.

Out of spec, wrong screw.

by Maurice, from MS, United States Written on March 25, 2021
This came with an A2 length screw, this advertises as an A1 sight, but comes with A2 parts. Is that false advertising? Save your time and money, and order from somewhere else. I had to wait for this order for a month, and it's not as advertised when it shows up, very disappointed.
Pros:
  • None
Cons:
  • Read above.
Best Used for:
  • Parts in a parts box.

Good sights

by Harrison, from UT, United States Written on January 16, 2021
Sights installed with no problem and adjusted easily. They’re a little stiff, and there’s a little extra material on one of the apertures which makes it slightly less than perfectly round. It isn’t noticeable when looking through the sights, and didn’t effect accuracy at all.
Pros:
  • Accurate
  • Inexpensive
  • Looks good
  • easy to adjust
  • Period correct
Cons:
  • Quality Control
Best Used for:
  • Retro AR build
Would recommend: Yes
