Swiss arms barrel swap from restricted to non-restricted

[Airborn_69]

What all is involved? do the gas ports need to be altered? Not interested in a complicated procedure as I don't care to mess with the engineering of the rifle.

Just a theory since Swiss rifles are one piece, in unison. If someone could duplicate the exact copy of the 18'' Carbines barrel but extend it by .5'' with the exact same flash hider it should be a close call. The other mods or options are totally experimental so its a hit or miss is my guess but we'll see.
