From Engineering, Parenthood, and a Solid Attempt at Adult Status:
I’m an Army veteran. I like M-4’s, which are, for all practical purposes, an AR-15, just with a few extra features that people almost never use anyway. I’d say at least 70% of my formal weapons training is on that exact rifle, with the other 30% being split between various and sundry machineguns and grenade launchers. My experience is pretty representative of soldiers of my era. Most of us are really good with an M-4, and most of us like it at least reasonably well, because it is an objectively good rifle. I was good with an M-4, really good. I earned the Expert badge every time I went to the range, starting in Basic Training. This isn’t uncommon. I can name dozens of other soldiers/veterans I know personally who can say the exact same thing. This rifle is surprisingly easy to use, completely idiot-proof really, has next to no recoil, comes apart and cleans up like a dream, and is light to carry around. I’m probably more accurate with it than I would be with pretty much any other weapon in existence. I like this rifle a lot. I like marksmanship as a sport. When I was in the military, I enjoyed combining these two things as often as they’d let me.
With all that said, enough is enough.
