bumpfire

Verb/ Bumpfire, or bump firing*, is a technique used with semi-automatic firearms to replicate full-automatic fire, using the recoil and weight of the firearm to engage the trigger. This technique can be used with any semi-automatic firearm by affixing the trigger with a stationary object and pulling the handguard forward to fire a round. Bump fire stocks, an aftermarket product which replaces the pistol-grip furniture of a rifle to accommodate bump firing, have recently come under scrutiny with their involvement in the Las Vegas massacre, although previously available for many years in the US. Bump fire is viewed by many enthusiasts as a novelty, ineffective for combat or self-defense due to the uncertainty of the technique and inaccuracy of sustained rates of fire.
