External adjusters are black, they do not have a coin/tool slot, and they have a higher profile.

My Original Caps Didn't Have A Lanyard So Of Course I Lost One In The Woods. Replaced The Older ACOG Cap With These And They Fit Fine.
Perfect fit and easy installation on my TA01NSN optic. If your Trijicon optic can be adjusted with a coin or small screw driver you most likely need the internal adapter. Check before ordering. Fast shipping.
