Apache Armament will be at the Greenfield show this weekend with a really nice 16" kit for $319 (no tax if cash). They also have Aero uppers for $90. That's a complete kit for $409, cash. Add in the free parking and the $5 entry and it comes out to $414, cash plus gas (LOL). I was looking at them at the Stout Field show and they look pretty decent. I was going to buy one until I remembered I have 2 in the safe needing assembly.
Did you mean Aero lowers when you said uppers? From the rest of your post it seems like you did.
