Many people may not know this about the AR15.

73. The 3-round burst option wasn't available back when I qualified.

Just semi-auto or full auto. I got yelled at by the range manager for selecting full auto when we were told to fire any remaining rounds we had. He didn't say not to, so I switched to auto and emptied my magazine. I put those six remaining rounds in the target, too, since I anticipated the muzzle rise. When he yelled at me, I just shrugged, and he went on his way.

But, clearly, full auto was a waste of ammo and would be in a real situation, too. Growing up, I had a tubular magazine Marlin .22, like a lot of kids where I lived, so I was familiar with using such a firearm. .22 LR ammo was pretty cheap, so we used to do rapid fire sometimes. It wasn't all that accurate, really, but fun, I guess. I was always more interested in how many beer bottles I could break with the least number of shots, so, I generally fired one shot at a time after aiming. Still, once in a while you just had to see how fast you could empty the magazine.

I can't imagine any use for an AR-15, so I've never been tempted to buy one. I stopped hunting, too, long ago, so my firearms are pretty much unused recently. I take them out once a year and clean and lubricate them. That's it. I keep them, though. Why wouldn't I?
