Recoil Inhibitor

  • "If the first shot hits their feet, the second shot probably goes up to their chest, the third flys over their heads, and anything after that you are wielding an anti aircraft gun." Such were the words of a gunnery sergeant describing the effects of firing an automatic weapon from the hip without aiming.

    Over the course of the evolution of the gun, primitive muskets were made more reliable, more powerful, more accurate, and easier to reload. But as weapons got more "automatic", I think one area of development was missing until lately, recoil reduction.

    The power and firerate of small arms are still being upgraded, the US military for example has finally moved past the 5.66mm NATO rounds used by the M16 and its variants into the more powerful 7.56mm NATO rounds used by higher performance weapons such as the M4A1 and the SCAR heavy. All this advancement in reliability, weight, and firepower still resulted in the same primitive recoil reducer in the form of a rifle stock jarring the shoulder of the soldier firing said weapon, someone seems to have forgotten to tell the firearm developers that the amount of kinetic force the target receives is always less than the amount of recoil generated.

    One exception to this trend however is the KRISS Super V, otherwise known as the Vector submachine gun. It has a recoil dampening device built into the receiver which makes the hammer that fires the gun move in a up and down motion countering the up and down of the recoil resulting in a fully automatic weapon of the .45 caliber with the recoil of a pistol.
    What I propose is an add-on which will dampen the recoil of any weapon, recoil is a phenomenon which occurs in two stages, stage one where the hammer hits the pin firing the bullet, and stage two where the bullet leaves the barrel and the gasses behind the bullet escape, pushing the barrel upwards. While the KRISS solved the issue by reducing stage one recoil, I try to take on stage two. After the bullet leaves the gun, an attachment that screws onto the end of the barrel captures some of the gas and releases a spring loaded hammer downwards against the recoil. After the gasses leaves, the hammer resets itself and waits for the next shot.
