The crappy neighbors up the road did call the sheriff's dept. and they didn't even care. They wanted to see it in action and got a big kick out of it so we just kept on making noise and had a good time. These neighbors or the type of people who shouldn't have moved to the country as they call the sheriff about everything, even when it isn't illegal, yet feel they can let mean dogs have the run of the place. The AR-15 has helped keep that problem under control. Yes, these people have called the sheriff on neighbors who are farmers because they didn't want to hear chickens, tractors, or cows mooing.
I also tried shooting my .22lr conversion with the cheap bulk Federal ammo from Wal-Mart and it didn't work. I lubed the slide with graphite and am using a PSA single stage trigger but it didn't work. I guess I would need a better trigger for this to work. Overall, I have found that the bulk Federal ammo is pretty good stuff and fires in just about anything.
Using graphite lube around Aluminum is not advised.
