Your rifles gas block reminded me of my son's rifle. I asked because my son bought an M&P15 just before Christmas. He put new Magpul furniture on it and a Sig Romeo4 micro dot sight and that thing shoots very well! It needs a better trigger, but dang he can shoot it. He has killed a couple coyotes that we called with it, one a hard charger that he rolled up damn quick. Not always easy to do in a heavily timbered brushy creek bottom. A crow sitting what I estimate at 150 yards, not bad for a zero magnification 2 moa dot.
Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
