Most Helpful Negative Review Non-Standard Sight Adjustment

Great concept for front sight

by Andrew, Verified Owner from NC, United States Written on July 29, 2025
My eye and brain prefer circle-in-circle sighting systems as opposed to post in peep sighting. I bought this to modify and use with a standard front sight tower instead of the ultradyne ecosystem. Just a little bit of time with a file to open up the end of the slots allowed the plunger to engage fine. I have a pair of ultradyne flip ups that are great as well so no matter what you're buying this for it should work with a little modification or as a drop in.
Pros:
  • Accurate
  • Target focused aiming is way easier than front sight aiming
  • great sighting system
Cons:
  • Some modification may be necessary
Would recommend: Yes
