Bump fire
Encyclopedia
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 firearm
s 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 forwards while the trigger fingers remain stationary. With revolvers, automatic fire can be simulated by using two trigger fingers firing offset.
All these 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 approved the device, they later reversed this ruling, two years after they had approved it for sale. Bill Akins received no compensation, and was forced to surrender his devices and customer list to the ATF.
Slide Fire Solutions produces a stock, the SSAR-15, which achieves a similar effect for AR-15 rifles, and which is approved by the ATF.
