I have 2 TC encore 20ga turkey barrels. The one was done by the custom shop and is blue. The other is factory camo. I have 3 turkey choke tubes 2 are TC and the other is HS Undertaker. . All 3 tubes fit the blued barrel finger tight . But the camo will not take the HS tube. One half turn and it is done Does anyone have idea why the difference '
