Hello...new to NWF, wanted some advice for a couple of things. I. Looking to purchase an assault rifle, and I read that the gun show is this weekend. Is that a good place to purchase either a new or used one? What would be a decent price for either a used or new one? II. Where is a good shooting range in the portland area? I have a few pistols that I would like to shoot, as well as a 22lr, and a new mossberg 12g tactical shotgun that I have been jones-ing to take out.
