@Kingfish That's a great optic, I'm sold on prismatic scopes like that for close range. I use a 1x Vortex spitfire, also prismatic, on my AR's and love it. Unlike standard red dots and holographic scopes I see a nice crisp image instead of a blur due to my astigmatism. Great scope for us old bastiges. I use the 1x so I can sight with both eyes open. My AO is mostly woodlands jungle so I like the wider field of view that 1x gives me. I still have BUIS just in case the glass breaks, and I wouldn't be afraid of inexpensive polymer ones like the MagPul if cost was an issue. For longer distances I have an AR-10 with a crisp 3x9 scope that also has a red dot in the middle. It's amazing how much quicker that little cue is for target acquisition. The green tip ammo is M855/SS109. It's better for penetration if you are facing folks with body armor, but won't defeat any designed for more than pistols. It's the same stuff the BATF unsuccessfully tried to outlaw months back. Still available, and not much more than XM193. Get it now, though, because I suspect an executive order will occur before long and the resulting panic will make it scarce and expensive.
