Yeah Teslong. I got the wifi version to use with my phone (iOs). I cleaned it so, so many times. I have the Hoppes coper eliminator and a bunch of other stuff. Still shoots good though. Better than me. I went out today, verified zero at 100, shot one 5 round group on a bench with bipod. I forgot my rear bags like a dummy, but was still a .6MOA group. Then went to the range with steel from 100 to 1500. First round hits to 855. Took a couple to get on target at 1035. 1160 gave me trouble as the wind wasnt constant. The hold was anywhere from 1/2 mil all the way to 3. I was happy considering I havent shot rifle in probably 18 months.
