The Optic Sight was advertised as as GREEN DOT thats what the GR Means, That being said I bid on it id then got a less expensive model Still a Good Sight But it was Boxed in The More Expensive Box.. I could hav spent a little more for a NEW one with a Warranty! They have the correct item, but told me they did NOT! Well I found it on the store page at the SAME price That I could get it from the Maker.. All TRUST Is Lost with this outfit... I did not want RED!!! I may have saved a couple of bucks, But that's not the POINT!!

The 507K is a great optic for it's size. I have 2, one red, and one green. I prefer the green. Love the options of 3 reticles. The overall size is nice compact and works well on my 365XL, 1911, and have my P320 with out hanging over the sides of the slide. Though the 507K does have backup iron sights built in to the sight body they are minimal and are not extremely effective. I would like to see of them taller and have contrast dots to actually be effective iron sights. Though this did not effect my overall rating.

Good build quality. Fit perfectly and looks custom made for Mossberg 590S. Controls are very intuitive and easy to adjust. Holds zero, even on a 12 gauge with larger 2 3/4" shells. Would recommend to anyone with RMSc firearm fingerprint.

Whoa, I really like this thing! It fits VERY nicely on Single Stack size Semi-Autos, like Glock 42 & 43s or the Beretta 80x. And the green dot is the "cats meow". I don't expect to go back to a red dot any time soon! Nicely done Holosun!! I will reserve durability judgement until I've had it a bit longer.
