First, GARR02, I hope you don't mind my semi-hijacking your thread as long as it ends up in you ultimately selling your upper (hopefully to me). For the couple who have asked, either in a thread or by email, I am not including the bolt, carrier or charging handle. My goal is to have my rifle magically change from a 14.5" M4 to a 16" M4 (hmm, could I magically get something else 1.5" longer?....different thread). That means I can't sell more than I get. GARR02 is offering his upper for a good price. I'm just looking to come out even, not with a profit and certainly, not with a loss.
