Yes the barrels are interchangable. I have two .50 caliber New Englanders, and a .54 caliber plus the 12 gauge. I bought my barrel from T/C Arms store. It is a great grouse shotgun.

hello, i have read a ton of infomation and talked to a lot of fellows over the last 2 years about black powder shotguns. Over those 2 years I found 3 people that seem to know what they are talking about and you are one of them. I just joined this forum tonight and posted a question in the black powder forum about the t/c new englander. i saw that you have one and would appreciate your help. I am looking for a 12 guage barrell, if i also buy a new englander .54 or .50 rifle if the 12 guage barrell will fit...meaning can you "swap" a .50cal and a 12 guage barrell in a new englander. thank you in advance for your help!
