- Really?Review by Bob
The dust cover door closes IF I try really hard, but wont open. I have to pull the pin and pop the cover off with a screwdriver!
I pulled the cover off another upper, and it worked fine, so its NOT the Aero upper.
The pic clearly shows a black cover spring. It may as well be chrome.
I havent ever tryed the forward assist....
