HS507K-FN 510 red dot plate

by Edwez, Verified Owner from GA, United States Written on September 3, 2025
The plate is well design well fit & finished. There is only one thing they shorted on, and that is the cutout for the o ring. The original manufacturer put the o ring cut out for a reason, and this co. redesign it, without taking into consideration the reason it was design that way in the first place. I understand it’s an easier production by cutting out a step, but for the price it should be as the original ones,as far the design is concern. At the end of the day they are not cheap$$$$$.

Great plate

by brain, Verified Owner from CO, United States Written on January 28, 2025
Very nice fit and finish for my FN509T. It should be nice for the price, and it is. If you need a plate and don't mind spending extra C&H is a good choice.
Pros:
  • Fit
  • Finish
Cons:
  • price

No issue with astigmatism

by NoviceShooter, Verified Owner from NV, United States Written on January 14, 2025
I wanted a closed emitter and in a green dot to make it easier to see with my astigmatism and keep the optic clean. So far it’s been a lovely add on. The auto right was feature is nice but tends to be troublesome in low light if using a flashlight on your firearm. I keep it 2 below the brightness setting and seems to be fine for all conditions. Based on this holding, I now want one for my ar15!
Pros:
  • clear glass
  • Ease of view with astigmastism
Cons:
  • None
Would recommend: Yes

great plate

by ming, Verified Owner from KY, United States Written on August 7, 2024
The plate fits super flush! It doesnt make it all bulky like it would if it was 2 plates sitting on top of each other like the original fn 509 optic plates
Some people might say 50$ is alot for a optic plate but i promise its worth the money!
