I see the phrase bump firing used quite a bit here - usually in reference to someone firing about as fast as full auto with an AK or some other semi-auto rifle.

What is it? How does it work? Can it harm the weapon?

Inquiring minds want to know?
 
Using the recoil of the weapon to actuate the trigger. It is similar to FA fire in speed, but not accuracy as you need to hold the gun loosely. Do a Google search if ya want to learn how.
 
If you can find a pro at it have them show you. I've seen guys do it firing offhand using a sling around their shoulder.

Basically you put your thumb through the trigger guard and then hook it on your pocket or the top of your pants. Using your other hand, pull the rifle forward until it fires. The tricky part is to keep your other arm/hand pulled forward and stiff so the recoil keeps the rifle rocking back and forth and keeps it firing. If done properly it makes it seem/feel like shooting FA.
 
Bump firing explained

I've never done it myself. I think I know the technique though.

The idea is to use the guns natural recoil along with a controlled push forward on the fore grip of the rifle. The gun is held low around your waist and is slightly supported in the rear with your hip. Your trigger hand is actually not holding the pistol grip. Your trigger finger is held over the trigger and is held firmly in place (attempted anyway) after the first shot.

What happens is the gun's recoil releases your finger from the trigger when the gun moves backwards. Your grip on the fore end of the rifle pushes the gun back into contact with you finger. You're not so much pushing on the rifle after each shot as you are providing constant forward pressure. So, each time the gun recoils, your push forward is overcome much like a spring being compressed. After the guns recoil is absorbed, your muscles push the rifle forward again into your trigger finger.

The effect is indistinguishable from a full auto gun except accuracy is quite poor. I understand that with practice and a lot of money. You can eventually become proficient enough to hit something. :) The only time I've seen it applied it was on an AK. I don't think the recoil on an AR is sufficient but I could be way wrong.
 
You can bump fire most semi's, all it takes is practice. I've seen a friend bump a Garand and Tony White (formerly of Barrett) said he's done it with an M82!
 
The first time I bump fired an AK, I smiled the rest of the day :).

Basically it is the recoil of the weapon pulling the trigger each time, instead of you physically pulling the trigger.

Lotsa fun :).

Bump Firing = Take couple bumps and start firing...

Seriously, It 's easy to do with your right middle finger, (in bird shooting position).

It's fun, but get up close to the berm before you try it. Especially the first time, there's not much controlling the aim.

Webster's defines bump firing as: a hell of good way to burn a lot of ammunition and not hit much.

I'm just messing around. I enjoy bump firing as much as anyone, especially with an M1 carbine. I learned on a WASR-10 and I used up a bunch of ammo. Now I'm out of money, destitute, and hungry because I shot up all my money bump firing.
 
Mryuk,

I don't believe a .22 has enough recoil to bump fire. I've tried with every automatic .22 we have around the house with no luck! It would be nice, eh? Perhaps if you had a REALLY light trigger? I don't know...try it!
 
that what i was thinking, light trigger and minimal overall mass. maybe a feather industries survival .22 or similar. My heavy barrell laminated stock 10/22 will most definatly not work, but I will try anyway.
 
Bump firing = fun -- just reach through the trigger grap a --beltloop-- pull forward with other hand and watch it spray!
 
Tried it today.....

Took the AK out for some fun and tried it a few times. :scrutiny: Double taps were a dime a dozen, but the most I was able to knock out were quads. Certainly requires practice to do proficiently. Then again with the drought on the 7.62x39 ammo, I might just savor the rounds I have on hand. :fire:

You do realize that the ATF must now ban thumbs. :evil:

Actually to be technically acurate they only ban the importation of thumbs. But only thumbs that are not used for sporting or classified as dual purpose. Then they release a letter stating that if you have enough US parts in your thumbs it is ok, but only when you sacrifice a sheep before using them. Finally they release a letter to clarify the ruling about thumbs, but the ruling makes no sense to anyone, including them, and they refuse to clarify it the issue further.

I got a visit from the local police once while bump-firing my AK at my range. Somebody called in with a report of someone with a machine gun. I think the responding cop was actually disappointed that I didn't have a full auto for him to try (he's a member of the same club). However, I did use the rest of my ammo teaching him how to do it.

My experience has been that it's a lot easier to do it with a sling. It can be done without, but it takes a bit more practice/skill. While bump-firing, an AK's rate of fire is slow-ish - sort of like a BAR. I taped a piece of rubber fuel line onto the inside front of the trigger guard (essentially shortening up the distance that the gun had to travel to reach my finger again) and the rate of fire was much higher and less controllable.

It's a fun way to use up a lot of ammo, just don't expect to hit anything on purpose.
