Do PTP Micromags use rail bushings?

Purchased and older MM and it did not come with a rail bushing. When I tried to put one in, it really didnt want to go into the body. Body is nickel plated. I had another one of these before, but couldnt remember if it had one or not.

They don't take a rail bushing. The hole in the micro body is smaller than the hole in the rails. That being said, if something damages the hole, then you can't replace it like you can a rail bushing.
