Unable to zero - Holosun Sub-compact HS507K-X2 1x 2 MOA Dot Red Dot Sights

The red dot was so far to the right out of the box that it reached it's mechanical limits of adjustability. This is my second Holosun 507k as I had the V1 and it lasted 10 rounds. I contact acted Holosun's Instant Messenger on Facebook and had the rudest customer service experience EVER! Luckily Optics Planet's return policy is amazing and I'm going to give Holosun one last try with another 507k X2. I have a Sig Romeo 5 (which is made by Holosun) and it is awesome! Super rugged and a phenomenal red dot sight. Holosun...keep an eye on your customer service reps and your quality control. You are NOT the only red dot sight manufacturer around. Optics Planet, I appreciate your fantastic return policy.
