An adjustable coupling apparatus for first and second spaced superposed bels of a sporting gun in which the barrels are secured at the rear ends thereof, to a mounting at the stock of the gun, the barrels projecting freely forward therefrom. The barrels are supported at the front ends thereof by a double collar which is fixedly engaged to the upper barrel and is slidably engaged with the lower barrel and holds the barrels in transversely spaced relation while permitting relative axial movement therebetween. A coupling device engages the barrels at an intermediate location along the length thereof for transverse adjustment of the spacing therebetween. The coupling device includes a rotatable wheel which can be rotated in opposite directions to increase or decrease the transverse spacing between the barrels. A detachable and interchangeable sight band is disposed above the upper barrel and is secured at its rear end to the mounting. The sight band is slidably mounted on the double collar and on the coupling device to permit free slidable movement thereof relative to the sight band which remains fixed.
An adjustable coupling apparatus for first and second spaced superposed barrels of a sporting gun, the barrels being secured at the rear ends thereof to a mounting of the gun and projecting freely forwards therefrom, said apparatus comprising holding means at the front ends of the barrels and fixed to one of the barrels for holding said barrels in fixed transversely spaced relation while permitting relative axial movement therebetween, collar means engaging said barrels at an intermediate location along the lengths thereof for transverse adjustment of the spacing therebetween, and a detachable and interchangeable sight band disposed above the upper one of the barrels and secured to said mounting, said sight band being slidably mounted on said holding means to permit slidable movement of said holding means and said one barrel to which it is fixed while said band remains stationary.
