So i have a UTG a2 style carry handle. It's not bad. My only huge problem with it is, the rear site knob. They are extremely stiff.
Someone on amazon worked it out to make it smooth.
Can anyone take the time to make a youtube vid out of it???
"I did find the rear sight to be a bit stiff and it seemed to "hang up" a bit when elevated. I took it apart and ran a 1/2 drill through the rear sight assembly hole in the handle body and re-finished the bare aluminum with Birchwood Casey Aluminum Black (an essential product any AR enthusiast should have on hand). It works fine now, no hang-ups and smooth"
