i love all of my .223 AIs.
my last two (a M7 and Kimber) were done at by Arnold at Capitol Sports, but were just set back and punched factory tubes. absolutly no issues with these. they both shoot better than before, and are chambered identical so neck sized brass from either can be used in the other. i also bought a SS Ruger MKII in .223 AI at a gun show that was also punched AI by Arnold at Capitol Sports. i think highly of him and his work.
but a 12#+ .223 with a 1-8" Brux barrel sets the bar high for sheer accuracy from the bags.
