I've been doing some thinking lately, which is scary. Very scary.

I have come up w/ the idea that I want to build me a 300+yd AR. I've never much been into long range shooting, but I do have my 82a1. It's just not very portable if SHTF. SOOOOO.. in keeping w/ the ammo I already have... I thought a rifle length AR.. 20"+?

What say you guys? I don't want to venture into a new caliber. As much as I would rather it be larger than a .223/5.56, I just don't want to collect another bunch of ammo. I figure I'm not going to be shooting at hardened targets wearing body armor, and a 5.56 should be more than enough for zombies.

I've started looking at rifle length uppers, and know NOTHING about them. I can't seem to find any builds that I like.. there is a place I've been getting bits and pieces from for years, but they're either out of business, or they broke their website for the past few weeks.. Their precision rifle uppers have always made me drool...

So about building one. I was thinking about a monolithic upper. I know VLTOR makes a rifle length mono. It's pricey but I figure I'm going to dump some $$$ into getting exactly what I want anyway..

What are your feelings on mono uppers? Yay? nay? Just go w/ a free float?
