All the over and unders' Franchi barrels are
interchangeable, Cr Md hammer forged, chromium plated
bores and monobloc junction.
The barrels interchangeability is due to the close
tolerances machining and to the spring loaded yoke
forehand, whose spring indirectly «loads» frame and
barrel, thus automatically counteracting the play which
can sometimes show up after thousand and thousand heavy
loads and lot of years of use and over-indulgence. The
ejectors of these over and unders will never go out of
timing and their life will be longer than that of
shotguns of the same type due to the close tolerances
and to the use of parts machined starting from a
forging.With the barrel interchangeability you can vary
the weight and the centre of gravity of the shotgun at
will; you can have a faster handling gun or a heavier
one with less recoil and less muzzle jump.
Furthermore, with interchangeable barrel groups it is
possible to have specific barrels for specific needs,
always choosing the right barrels for the load you want
to use (different loads have different burning rates of
the powder and/or lead charge).
