Skeptical at first - Viridian OPMOD Omega Closed Emitter Green Dot Sight, ACRO Mounting w/RMR adapter And High Picatinny Mount

I have owned quite a few red dots in my day. I generally prefer vortex due to the warranty however, I wanted a closed emitter green dot. So options were limited and price is a big factor. I took a leap on this product, not knowing anything about it, and I will say that this is the only red/green dot sight I have looked through or used, that I can make out a perfect dot. Sometimes indoors, it will be a little fuzzy or blurred however Outdoors it’s a perfect dot. So I actually own two of them now! This is also my first review ever. If that tells you how excited, I am about the product. However I have not tested it for accuracy, repeatability on paper yet. I will say the only frustrating thing that I have run into is mounting it on a full size Glock 9 mm slide. Both slides are Zaffiri which has the posts in the RMR cut out which needed to be milled off and a #4-40 x 3/16", Phillips Flat Head Screws, A2 304 18-8, Stainless Steel purchased from Rusty Bolt shop on eBay was used to mount the plate on. I hope this helps.
