Several weeks ago I was at the 50 yard range with my CZ-452. I having fun learning to use my scope. During the cease fire some guy complimented me on my goups and asked what caliber I was shooting. I told him it was a .22. He acted like he didn't hear me right and asked if my rifle was a 22 magnum. I said no 22 LR. He told me I should he shoud be shooting something bigger. I noticed he was shooting what looked like a Mini-14. near him were 4 other rifles that looked like AK's along with a couple of surplus ammo boxes filled with bullets. I asked him if they were his and he told me that he bought them because he was concerned of a future was presidential ban. He started bad mouthing the president. Well I don't like talking politics and kind of backed away from the meaning to end the conversation. At the next cease fire I overheard him telling an older gentleman that he was in law enforcement with the BATF. I'm think he was a BS'er but it possible that this guy was working undercover?
