Terrible qc - Barska AR15 Standard Carry Handle

I knew going this product wasn't going to be high quality. They are a low budget brand by default. But this was surprisingly bad. The rear windage knobs was almost inoperable. It was pinned on crooked to the spindle. the rear sight was so loose it flopped back and forth. the finish is, Per Barska standard, temporary to describe it best. It did fit well on the rail. Got this put of curiosity and it didn't let me down lol. Don't buy cheap save your money and get the $60 one. There are several options on here.
