Cleaning both my uppers for my ar. Going to be selling/partial trade with my varmit upper for a vltor ar decked out and also cleaning my colt match upper. Went and put the scope on the colt upper and took the sun shade thing off it too and took the red dot off it. Gonna put the red dot on the vltor when I get it. the varmit upper is so much smaller then I thought when its off the lower.
