Briley's 1911 Commander Spherical Bushing

[PerversPépère]

Hi!
I was wondering if anyone among you has installed this particular bushing.
Any comments on how it works and is it a good aftermarket item for the 1911?

I have their bushing on one of my 1911's and in one of my smiths... It can be a pita to get the barrel in and out as they are really precise.. But I've had no problems with them.. I think they are pretty slick...
