I'm just wondering that since: "The forces produced by the pressure of the propellant gases act rearward along the axis of the gun barrel. These axial forces are resisted by the mass of the gun, but because the mass center is offset from the bore, a couple results, thereby producing accelerations of the gun barrel in directions perpendicular to the axis of the bore."
Has anyone in the manufacture of guns, designed such a weapon that has a mass with it's center of gravity along the boreline, thus eliminating the couple that results in muzzle rise? This gun would look a little weird, because the stock and mechanism would result in the barrel being lower than normal. This would result in an unusually high scope to bore distance, but I'm sure it would produce better accuracy.
I would think that the more detrimental attributes (ie muzzle rise) that you can eliminate, the better your accuracy must be. Ergo, if you take a Mini-14, and remove the stock and just fire it with the innards and trigger assembly by holding onto the reciever only somehow, wouldn't that improve things?
Just my wandering brain...
