I fit another set of barrels to my wifes Parker- took about one hour. The gun was a model without a wear plate on the barrels and the new barrels came from a latter gun that used a wear plate and didn't have it. So it also took some time to make a wear plate and fit it. The dolls head was no problem with mine. I did it because the cut barrels were twist damascus and the new one was a nice pattern damascus which I have sent out to Dale Edmands to redo. She'll be able to shoot skeet with the cut 26" barrels or SC's with the 30" ones choked IC and LM. Go for it. Paul
