Sure it's a Anderson upper receiver,24 inch Dpms barrel, spike's gas tube,not sure the make of the low pro gas block and a 15 inch aero handguard. I took the barrel nut to a machine shop and had it milled to 1.03 to fit the barrel
The inside of the barrel nut was .98 and the barrel was 1.03 so the barrel nut wouldn't fit on the barrel. This is the second time this has happened to me using bull barrels. I have a friend who is a machinist,so for me it's not a big deal.I'm not sure on the weight but man it feels good
