Can't understand it either. Your aim is thrown off while doing it. I'd rather make the rounds count than simply have nothing other than a lot of noise and cordite odor.

I guess my viewpoint is simply if you feel an uncontrollable urge for full auto fire, enlist in the army. They've got millions of weapons already set up for full auto. and they pay for the ammo.

Why are you opposed to it and what do you mean make the shot count? Is my life dependent upon making that coke can explode? If you aren't going to help I don't need your condescending opinions. Why fire it at all? Because its fun. This is why I don't come on the forums often.

Thanks for the help to all the people who offered suggestions that were constructive. I just can't stand everyone being on the offensive ever time anyone posts something on here.

No one went on the offensive. We just started discussing bump firing.

Sorry I didn't realize y'all were trying to help when you criticized the way I fire my guns and then told me to stop my problem when bump firing by not bump firing.

semi-autos arent designed to fire that fast. what your experiencing is called hammer follow. this means the trigger is releasing the sear before the bolt carrier has fully locked the bolt into the chamber.

installing a heavier hammer spring will detonate a round outside the chamber leading to a catastrophic kaboom. the possibility is loss of life by you or a bystander or severe injury.

even with a normal hammer spring this can happen. its good reason why things like the slidefire or bumpfire techniques are an astoundingly bad idea

my prediction is that at some point someone is going to die doing this or using the slidefire from kabooming a gun that is not designed to run that fast.

I recently swapped out my first gas block, and after test firing and re-zeroing the rifle, I proceeded to bump-fire two 30 round magazines. I wanted to make sure I had the gas system perfectly in line, and that my tinkering did not throw the rifle 'out of time.' What better way to test this than sending 60 downrange in 30 seconds?! Now I said that to say this: I believe these other gentlemen have hit the nail on the head, but could the underlying cause be a timing issue? I'm new to the platform, and I'm just brainstorming here, but would y'all experts suggest that the poster experiment with different buffers, springs, extractors, etc. Maybe check gas tube cleanliness and alignment? Properly staked gas key? Well lubricated BCG? Unimpeded locking lugs? Seems like something must be causing the hammer to ride the bolt home...
