let me begin by saying that i'm excited and disappointed all in one. i got my 16"kit from m&a today and i first layed it all out to survey the parts. the first thing i noticed was the delta ring was scratched up, next the finish of the upper receiver was really shiny. i figured it was because of the oil on it so i found a clean rag and wiped off the excess. nope! still shiny, the finish was suppossed to be similar to that of my dpms lower. kinda flat looking, the upper looks like wal-mart semi gloss. i layed the parts out for thestripped lower and the rear detent spring for the takedown pin was not in the bag, panic filled me. i called m&a and spoke with "doc". let me say that if a company answers the phone they should feel obligated to help you, not tell you "we're closed call back tomorrow. if your closed don't answer the damn phone! i headed back to the box and low and behold there it was hiding in the crevice of the box. why wasn't it placed in the bag with the other parts. where is the quality control? enough bitchin after it all went together the only thing that didn't fit well was the pistol grip. tomorrow i will see about firing the weapon. i guess it's a good thing i plan on building other ar's so i can give this one to the wife to beat up
