I show up at US optics this morning with my scope. I let the receptionist (jessica) know that i just purchased the scope from someone else and wanted it looked over if possible. She asks me what i got. An sn3 3.2-17x37 mil/mil, blue reticle and so on. Then she asks me for it, looks at it and starts to rattle off info, about the build date, the knobs, and adjustments. Wow. Then out comes Mr Jason. He takes the scope and invites me to the back. I am thinking no way. I get back there and we are in the middle of the building and can see the machine shop area, the shipping area, final assembly. He asks me do I know how to properly clean it. He shows me. I am trying to pay attention and check out the shop too. He asks me where the tool kit is so he can show me how to adjust it. I tell him I did not receive one. He gets someone to retrieve one. Then he asks me where the end caps are. I tell him, those where not an option. He gets someone to get me a set. He then asks me what am i going to put it on. Well mostly on an AR. He tells me if I have time, he can zero it and show me. Are you kidding me? Then takes me into final assembly and resets my zero. Shows me how its done, and how to adjust it for my bolt action. Then Mr Arnold comes by and starts to explain the water proof cap for the erek knob. He asks me where mine is. ha,ha. He asks me if I have a preference, if I have a choice sure, make it Marine Corp cap. Sure enough with a new o-ring too. Just before I get ready to leave Jason comes back with a spec sheet on the scope and tells me no charge on anything today. If I need additional help come back anytime. Can you believe that. As I walked around everyone was busy but they made time to say hello to me. I am nobody (just like everyone else) but they made me feel like royalty. Today was a great day thnx US Optics I owe you guys+pretty girls donuts.
