This is a service where rifled barrels and coupler are machined and marked to be joined into a longer barrel.
The rifling will be able to be lined up using the match marks and the barrels will connect end to end with a tiny seam functioning like one long barrel.
Using this method you can get virtually any length rifled barrel you want.
Add the barrels you want joined to your shopping cart and then add this item. One per join.
Join two barrels: Order the two barrels and one barrel extension.
Join three barrels: Order three barrels and two barrel extensions.
Join four barrels: Order four barrels and three barrels extensions.
Describe what barrels you want joined in the comments area below.
EXAMPLE: I would like to join two 4ft 2in schedule 40 rifled barrels into one 8ft barrel.
