I've got a Burris 1x4 that's pretty nice. Midway had a sale on them when I bought it, has the XTR reticle. Can't go wrong with a Leupold either, they have a 1" tube 1x4 w/ their SPR reticle that you could calibrate for your rifle. Nikons are supposed to be good too. In the end a tacticool reticle isn't really needed, anything that is built sturdy will work.
I gotta add though, if it's something you have intentions of surviving a full on Red Dawn scenario don't let price come into play. That's like going in for brain surgery but telling the doc to use some kitchen knives and your Home Depot saw to do the work so you don't have to pay extra. I'm not saying the most expensive gear is the best, only that quality often times has a price associated. Stack the deck in your favor I say.
