Greetings, I have to humbly (and embarrassingly) ask where the best place to learn to Zero an AR is. I have nice iron sights and a hologram with zero magnification. I believe that I will be getting a scope this Christmas. Is anyone in the Portland area (Tri County Gun Club) that can show me in person. I would be willing to tip the teacher but I need to share that I don't have a ton of money to offer. I would do the utube thing or other internet sites, but I'm a do it to learn it type of guy. Thank you in advance for your time.
