Well, I finally got my invitation to join DPRC (!) and I'm excited to soon be able to shoot outdoors and at distances beyond 25 yards. I've only ever shot at an indoor range, and that's been mostly pistols. I have a TCR22 rifle and an AR-15 (BG Defense with 16" barrel), but I've only shot them at the indoor range at 15-25 yards with red dots. What should I be looking at for shooting at DPRC? I'm guessing I should get some kind of scope to start with, assuming I can get by with the rifles I have. Thanks in advance for suggestions!
