Lets say a guy (me) has a Nitro Special that has spiffy 26" barrels were to stumble on a set of 28" tubes and forend from a Western Arms gun in the same gauge. Would there be a snowball's chance in hades that the Western barrels could be mated up to the Nitro without major trouble?
I guess I'd prefer actual hands on experience, rather than speculation, but, feel free to post speculation, if you call it that when you post it.

Many thanks in Advance,

Best,
Ted
