Hey guys and gals. I moved to Portland about a year and a half ago. I have an AR-15 and would like to know where I can go shoot it. I don't really want to get a membership at a range. Plus my AR shoots 7.62x39 and I just get the cheap steel case stuff to plink with and a lot of ranges don't allow it. Just looking for 50-100y to plink with my red dot. Looking in a 30 minute proximity of Portland. Thank You!
