Ok i got a email ad for a stock the dose bump fire on AR15/M16 but the stock has to be M4 was woundering if any one has done bump fire or used any thing like this?They were at the shot show and sell the every one.The stock just fits on where the old one gose. TY
Bump firing is the act of using the recoil of a firearm to fire multiple shots in rapid succession. This process involves holding the foregrip with the non-trigger hand, releasing the grip on the firing hand (leaving the trigger finger in its normal position), pushing the rifle forward in order to apply pressure on the trigger finger from the trigger, and keeping the trigger finger stationary. The firearm will recoil and then return to its previous position after the round has been fired first resetting and then pressing forward against the trigger thereby firing successive shots.
The rapid bursts from semi-automatic firearms simulate the discharge of automatic firearms. Even though a large number of rounds are fired in rapid succession, the trigger finger initiates each discharge; therefore, fully automatic fire is not actually taking place.
A similar method can be employed with semi-automatic pistols, in which one hand holds the grip, two fingers are placed in the trigger well, and then the grip hand shoves the weapon forewards while the trigger fingers remain stationary. With revolvers, automatic fire can be simulated by using two trigger fingers firing offset.
All of techniques greatly degrade the accuracy of the firearm, due to the necessary jerking of the weapon. The techniques trade accurate aimed fire for making the noise associated with fully automatic weapons.
Devices (from complicated, specially made triggers to the low-tech rubber band) are employed in order to cause or facilitate the "bumping." However, not all such devices or modifications are legal. A famous example in the United States of America is the case of the Akins Accelerator for the Ruger 10/22. Though the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) initially allowed mechanical devices for producing rapid fire, this ruling has since been reversed and currently the device is illegal.
