The shoulder gun I have always liked the most is the American revolver repeating riffle shoulder gun which utilises the same principle as a standard revolver but with a shoulder buttstock and a long barrel. Ever since I saw these in the Western movies I have loved them.

Contrary to what people in the US think, these guns can be made extremely accurate and there is no reason for not being such. The leverage of the action mechanism can be made long to reduce the force needed paying with extra travel path of the trigger. They can also be cocked for even more accurate and easy first shot and the path of the trigger can be lowered as well as the force needed when cocked.

The advantages are many. No need to cock the gun. The cylinder can hold many bullets, more than 12 in one circle. Bullets can be loaded immediately after a shot or a few. Do not throw cartages and are much safer than a normal gun as the gas pressure is thrown away from the face of the shooter and there is no possibility of anything to prevent this. The simplicity also bring even higher reliability. The disadvantage of the gap between the cylinder and the barrel can be compensated for by a closer which can be hard attached to the barrel or the chassis and automatically close the gap after positioning and slightly before firing. Similar system is available in the standard Nagant type revolvers which were used even throughout the World War II by the Red Army as well as before the Russian Revolution by the Tsar’s army.

The gap closure allows the use of a suppressor. In standard mode, the cylinder does not protrude higher than the barrel which means a more accurate barrel line can be used instead of the inaccurate protruding standard aims which also need distance compensation.

The action, the magazine ( the cylinder ) as well as all or most of the parts of the action are positioned very close to the trigger hand, thus to the shoulder which means the weight thereof, will not introduce extra leverage force to the hands, mainly to the holding hands which means the gun can be aimed more accurately, very similar to the bullpup action weapons. Except the gun is more reliable than the bullpup weapons because of the said reasons as well as because the bullets are not as close to the face of the shooter as the bullets of the standard bullpup action weapons.

Along with this, this gun can be made possible to carry a huge amounts of bullets in the concentric bullet circle cylinder at the expense of the protruding cylinder and the need to have protruding aims which can be hidden and used only when changing the concentric bullet circles.

Here is what I want to say : the cylinder can have standard bullet holes positioned next to each other and close to the outer wall of the cylinder. This is a standard configuration with any revolver. However, because this is a shoulder gun and not a hand gun, the cylinder can be made light and strong and very wide. Because the cylinder can be wider than the cylinder of the hand gun revolver ( designed to be put in a pocket or a holster ), the shoulder gun can get more holes for bullets of a given caliber. Also, other holes can be made in another circle inside the cylinder, concentric with the outer one. More than two concentric circles are possible. The question is how to shoot the bullets out of the inner circle ( s ). To do so, either multiple barrel and hammer arrangement is necessary ( the worse solution ) or a movable hammer and or barrel up and down ( also a bad solution ) or, the best, movable cylinder up and down and a mechanism to recalculate the angle of rotation between two adjacent bullets of the inner circle unless a lot of room is used in the outer bullet circle ( not a good solution ).

This way, the shooter can shoot the gun just as every revolver hand or shoulder gun. Say, the shooter can have 12 bullets to shoot. Then, the shooter can lift the cylinder up and align the second circle to the hammer. A mechanism for rotation when the cylinder is up will be available as well as a different angle of rotation between every two adjacent bullets. This mechanism can be a simple gear transmission with movable freewheeling gears ( best ) or a chain or belt driven such. Then the shooter can shoot the bullets lined up on the second circle, say, an additional 8 bullets. In case of more concentric bullet circles, the shooter would need to lift the cylinder which would also change the gears for the next concentric circle. Again, the disadvantage is the cylinder would protrude when changing the concentric circles. Thus, a retractable and rotating aims and distance compensator are necessary. However, in most cases, the shooter would only use the outer bullet circle ( the standardly aligned 12 bullets in the example ) which the shooter will reload after shooting of each or a few of them. The inner circle may not be used and may stay only as a precaution in rare cases where the shooter may exhaust the first circle unable to reload.

A modified standard cartage extractor can be used to extract only a desired cartridge and not all. The simplest way to do so is a standard cartridge remover which is segmented per each bullet of a given circle, say a spring which extracts only a few millimetres of a cartridge aligned to an aperture and cannot extract the rest although acting upon as they are closed from the top and cannot move out.

All these are complications. Just a standard, say, 500 Smith and Wesson Magnum or Magnum 45 ALIKE revolver repeating riffle shoulder gun would do just as fine. More, this can be made in a standard removable buttstock configuration. Even the barrel can be kept short and a LONG suppressor can be optional. Thus, the shoulder gun would be possible to be used as a hand gun as well as a shoulder gun as one of the original ideas of the 1980’s. A good idea may be to make the suppressor aligned with the barrel and not wider as well as with a very accurate thread which will align the aiming line which is along the riffle.

The idea of a barrel line aim is available in some of the top quality Finish guns. A lens is welcome as long as the lens is aligned with the barrel and does not protrude.

For more accurate application the removable lens can be fitted with a distance compensator. This is because the thickness of the barrel may need to be compensated for for sniper application in case of any.

Add 20th and 21st light and strong Titanium alloys and, I think, this 1800’s design will become the most reliable, dependable, powerful and the safest shoulder riffle.
