DANG! will this guy ever go away?
Two more questions, one, are your varmint/target barreled uppers chambered for the .223Rem. sporting specs? (SAAMI I believe) or the 5.56 milspec chamber? And two what is the definition of an "air gauged" barrel? Kinda like the question on the phone (what is a "high-riser" and why do I want one?).
I shall quit for a while!
