I know many people have sung thier praises on here before but i'm going to do it again. I purchased a Sig 522 a few weeks ago and asked on here about what I should get as far as optics. I was recommended to check out primary arms. I first ordered the Green Dot reflex sight. I got it in about 3 days. The battery connection wasn't very solid so I called and told em. I had a shipping label in my email within 15 minutes. They got the sight back and I got an email about 10 minutes after USPS said they delivered the package. THey issued me a coupon code for the amount of my purchase. I went ahead and ordered the micro dot sight today. They shipped it out within an hour of me ordering it! So hopefully I have my new red dot on tuesday or wednesday. I can tell you the customer service was A++++ I will be using them in the future next time I need some accessories. Check them out if you haven't already.
