I have a set of companion tubes in 410, 28 ga and 20 ga with screw in chokes.
Tubes are 26" long and are for Perazzi O/U. I used these in 30", 32" and 34" barrels with good success $750.00 delivered. Tubes a in great shape! Dan
excellent price for these tubes. don't be put off if the tubes are shorter than the barrels. Back when subgauge tubes first came out, it was not uncommon to have tubes shorter than your barrels for balance reasons. A top skeet shooter, Luke Deshotels, used to, and maybe still does, shoot a set of 25" tubes in a set of 30" barrels to get the balance he wanted.
