rtab1,
I didn't get it either. I told him I needed a 5" bushing bbl with a Wilson Nowlin ramp. On their web site most all of their 5" bbls are bull style, but they have a full selection of 6" bushing bbls. Maybe the bushing was a problem, I don't know. Anyhow, Bar Sto took good care of me. Crossing my fingers that the semi-drop in proves to be a true drop-in. Be nice not to have to run to the smith for a change.
