Most Helpful Positive Review Awesome quality
I didnt see anything online about this sight but it looked a lot like the expense troy iron sights but the price was actually reasonable. Im happy to report back they work very well. Accurate on an aero m5 build right away. Tool-less adjustment, all metal, USA made, looks great, accurate. Theres nothing I don’t like. You can also stand the rifle upside down on these sights perfectly which is just nice. Well done and worth the money.

Good Sights

by Rammy, Verified Owner from AZ, United States Written on April 14, 2026
Overall these are good sights and well designed. The QR code that is on the package in order to access instructions does not do anything. Also there isn't installation or adjustment manual for these sights on the Williams website. I did call the manufacturer regarding the torque specs and they were able to help me out.
Pros:
  • good quality
Cons:
  • No Installation or Adjustment Instructions
Would recommend: Yes

Great for the price!

by Dylan, Verified Owner from RI, United States Written on March 28, 2026
I am using these as back up sights on a SW Sport 3. They fit on the picatinny rail flawlessly. The QR code that gives installation instructions sends you to the company's homepage, but not to direct instructions. I called them, and their customer service is phenomenal. 20-25in/lb of torque and some blue Loctite and you're good to go.

Some questions I had: could this fit under a Holosun magnifier? The answer is yes. So I am running the rear sight on the last set of picc rails and I am able to put the magnifier over the sight when it's not deployed. They are all metal, and are seemingly very durable. I have yet to really use-and-abuse them, BUT they definitely do the job. I can co-witness them through a Holosun ARO.

I hope this helps anyone considering this product.
Pros:
  • EASY INSTALL
  • fitment
  • Customer Support
Cons:
  • None

Budget flip ups, ok for the price, get what ya pay for

by N.T., Verified Owner from AL, United States Written on April 30, 2024
They work, and manual deployment helps keep cost down. They mount to the rail solid. Although when up they have some play when touched/pushed to the rearward position. I got them for a budget AR build, so for that they are fine. I trust the aluminum more than other polymer ones out there. In all fairly happy with them. Just be aware the windage knob can be bumped and knock you off zero easily. (Not much force needed to rotate it) But if you are OK with fixed iron sights I'd spend the $50 more for the Daniel Defense ones. Or $100 more for troy flip ups. But if your budget is tight, these are fine.
Pros:
  • Flip up, aluminum, and cost effective
Cons:
  • Have rear play, windage knob easy to turn
Best Used for:
  • Budget gun, beater gun
Would recommend: Yes
