We are hearing a lot about bump stocks for rifles after the mass shooting in Las Vegas Sunday. Replacing the standard stock with a bump stock allows a semi-automatic rifle to file like an automatic rifle similar to a machine gun. Spencer Lemieux is a gunsmith and owns the Raven Head Arms Store in Bellevue and explains how they work.
Lemieux says, “It is a pistol grip and a stock are combined into one unit. It has a fake trigger that sits on the side of where you would normally put your finger in to pull. Then you actually pull the rifle itself forward so that the trigger contacts your finger until the firearm fires. As soon as it fires the recoil throws the rifle backwards because it can slide inside of the stock. Your muscle tension is already pulling forward so the rifle comes back forward and bumps onto your trigger finger.”
Lemieux says they are not easy to use. In order to keep this momentum you have to apply a certain amount of pressure forward. Too much or too little pressure is used the gun won’t recoil properly and you won’t get the desired results.
We asked Lemieux if bump stocks serve a purpose. He says, “It is something that is done for fun basically. If you want to shoot fast and waste a lot of ammo, great. You are not going to be hitting a whole lot with it.”
Lemieux doesn’t sell bump stocks but says he has gotten a few calls from people asking if he carries them. Lawmakers are talking about banning the sale and ownership of bump stocks after the mass shooting in Las Vegas. Lemieux says that happens every time the word ban is mentioned regarding firearms.
Several retailers, including Walmart, have pulled them from their shelves.
