Abstract
An adjustable means interconnecting the muzzle ends of barrels in an over-and-under firearm to adjust the distance between the muzzle ends of the barrels to alter the point of impact of projectile means discharged from the barrels.

A screw means is provided for adjusting the position of the lower barrel within the vertical slot of the yoke.
Claims5
In a double barrel firearm having an upper barrel that is superimposed over a lower barrel, an adjustment means connecting said upper and lower barrels for varying the point of impact of projectiles fired from the lower barrel relative to the line of sight of the firearm, comprising:
- an elongated yoke fixed to a muzzle end of the upper barrel and extending downward therefrom;
- said elongated yoke having an elongated slot formed by parallel yoke side rails for receiving a muzzle end of the lower barrel therein and for enabling the muzzle end of the lower barrel to slide vertically along the rails within the slot;
- adjustment means mounted on the yoke and operatively connected to the lower barrel for manually adjusting the relative position of the lower barrel within the elongated slot to adjust the relative distance between the muzzle ends of the barrels to vary the point of impact of projectiles fired from the lower barrel;
- and
- locking means associated with the adjustment screw for manually locking the adjustment screw to hold the lower barrel at a preset vertical position within the yoke slot.
