Dave, if I remember corectly gauge is downstairs it is 16" long so yes you could do 32" barrels, as you can measure from both the front of the barrel and the chamber area. Also Jon gives you his cell number in case you have any questions and it is made here in Michigan....
Yes Jack I called them to question the wall thinkness that was posted on all three of the 16 ga guns. Bill got back to me the next day and said the catalog was wrong and proceeded to give the wall thickness for all three guns, I hope the buyers of those other two Parker 16 ga's have the wall thickness checked they maybe holding a bomb
