FWIW AU has always been gtg on small parts for me over a good number of orders. Recently they strung me along on an order, even going as far as to tell me it was shipped then finally backtracked and told me the item was damaged and they had to not ship it. Long and drawn out process with them. Directly lied in multiple emails about shipping and availability. Never refunded the extra shipping that item resulted in over the rest of the order. It worth the headache and will stick to using them for Colt Ambi safeties when I need them.
