Started looking around to order parts for the next build, Looking to build a 24-28 ga smooth bore as the next one. Well barrels arrived Friday, I felt the weight of the box and said OH bOY something ain't right. I unpacked the box to find two 1" across the flats 45 rifled barrels 30" long. I would not feel so bad if they where 13/16" across the flats. anyone ever filed 3/16" of metal off the barrel flats before? LOL. It would cost me more to ship back than to try just to reorder the correct item again. who know I might get some 42" 40cal barrels next. LOL.
