Sounds Grendelicious!!! Please keep me updated toward his progress. I'm still on the fence as to which to purchase, The 24" AA Upper or the 24" J&T kit. I still have yet to talk to the J&T people for specific dimensions on their barrels. I want an adjustable gas block or at least one that will allow me to turn off the flow of gas for single shot use. My future plans are to buy one of AA's Side charging upper receivers and a 28" 6.5 Grendel barrel from Krieger.
