              Awesome red dot for an awesome from a great company

              The title says it all. Not a lot of companies offer excellent service like this company did to me. I ordered an open box at3 red dot and I ask if they can also offer me an optic mount for a reasonable price and the customer service rep(I forgot his name but I think its mike) told hes gonna send me a quote on my email that I provided. When I check the quote he gave me 50% off on their proprietary mini riser mount. On top of that shipping is free. I was shocked to see on my email that the item was shipped on the same day I ordered it. I'm like "wow" you guys are awesome in every aspect. I cant thank you enough. Definitely would come back to you in case I need some more stuff.

              Thanks for sharing your experience, Dario. We work hard to meet expectations like yours, we're glad we hit the mark for you. - AB
