UL Mainbody

[yoyoma]

Can someone help.. I just got a UL mainbody for my minimag and I can not get the twistlock off of my frame. How can I remove this? I removed the allen wrench part with the spring inside but can not remove the gold part of it.

You need to carefully tap that brass piece out with a punch and hammer. It's pressed in there and held in by the tight fit. There are no threads or screws holding it in. Just watch not to hit the rail and leave a ding.
