Description

Insert barrel attachment for firearms. Subject of the invention is a so-called plug-in barrel attachment for firearms. From the older facilities in this way the device according to the invention differs essentially in that one on the barrel muzzle expediently to be yeast sawed like a bayonet lock Sleeve with N female thread cut into the central mouth opening for the ammunition comes into which the insert run directly or indirectly with screw thread located at its end to the required depth is, with the definition of the easily adjustable and rotatable barrel through Lock nut takes place, which is screwed on <las running end and I against the Pressing on the sleeve.

The innovation is shown in Figs. I to 3 in an exemplary embodiment illustrated. Fig, i shows the new plug-in barrel attachment on a pistol arranged, in front view with partial section, while Figs. 2 and 3 are those Parts that belong to the insert barrel fastening are shown separately again.

The insert barrel 3 (Fig.3) has a thread 9 on the front end which a nut 8, which is used in the manner of a lock nut, is rotatably seated. 'With 5 the sleeve is referred to, which is attached in any way to the barrel muzzle can be. Nut thread is cut into this sleeve so that the plug-in barrel 3 inserted directly into the sleeve and screwed to a corresponding depth can be, with its Festkleinmung by the Gegennutter 8, which against the Sleeve 5 is tightened, takes place.

This relatively simple device is the great advantage achieved that the attachment of the insert barrel very quickly to any desired Insertion depth: I have it enabled. As a result, the insert barrel can be used in any The desired position can be brought to the Z'erschlußstück the Schußwafe, whereby the Adjustability and sensitivity of the exercise cartridge carried out within the broadest limits can be.

With this arrangement it is also very easy to detect lateral deviations to regulate the shots by turning the insert barrel around a corresponding Angle twisted in the gun barrel of the firearm and then again by Gegenmütter stuck.

In the illustrated embodiment, there is now a special embodiment this basic idea is illustrated by the fact that the sleeve 5 itself is expediently like a bayonet lock is designed so that they can be pushed onto the muzzle of the firearm or of the gun barrel and then twisting it sideways behind glass grain .1 hooked up who (i: n can.

The attachment of the sleeve to the barrel muzzle takes place in in this case by a sleeve 6 equipped with an external and internal thread, 7, "-which is screwed into the sleeve 5, whereby it is against the mouth of the rump and thus on the one hand the l) ajotiettverschluß-like in the Running attached sleeve 5 clamps at the bullet barrel end and on the other hand that Screwing the bullet barrel 3 into its central thread equipped with an internal thread Drilling permitted, with the clamping of the Ei @ nstecklaufes 3 again through Lock nut 8 takes place. Do you want or have to change the position of the mouth opening of the insert barrel 3 change something to the firing pin of the firearm, you only need the lock nut 8 to solve, whereupon you can move the insert barrel any piece in the direction can move its soul axis.

In the same way, if necessary, the insert barrel can be increased by a small one Twist the angle to the right or left, whereby the longitudinal displacement then occurs is so insignificant in the soul axis of the Einstecklaufes that it is without further ado can be neglected.

Claims (2)

PATENT CLAIMS: i. Insert barrel attachment for firearms, thereby characterized in that the plugged onto the barrel muzzle, expediently like a bayonet lock to be fastened sleeve (5) has a central mouth opening with an incised thread has, in which the plug-in barrel (3) finite screw thread located at its end (9) is screwed to the required depth, the setting of the easy adjustable and rotatable barrel (3) by lock nut (8) is carried out on the running end is screwed on and presses against the sleeve. 2nd embodiment according to claim i, characterized in that in the sleeve (5) one with outer and Internal thread equipped lining sleeve (6, 7 ') is screwed, which is against the muzzle of the projectile barrel is supported and thus on the one hand the sleeve (5) at the end of the barrel clamped and on the other hand the screwing of the bullet barrel (3) in their with internal thread equipped central drilling permitted.
