I took my AR to the range today for the first time and i found every time i pulled the trigger it would fire 2-5 shots, i could never get it just to fire one at a time.
Has anyone ever run into this before? if so is there a fix for it?

Thanks C
 
Was it slam firing? I have heard about this with the SKS and IIRC the solution is to give it a good cleaning. Can't comment specifically on the AR though.

Why fix it, that sounds awesome! Just wondering... does the hammer drop once the bolt is all the way forward? or does it ride the bolt?

Not sure it fired so quick i wasn't able to tell,as for being fun, it scared the crap out of me the first time it happened as for the others at the range they all had questions about it for me.
 
Does it only stop when the mag is empty? Mine once had a problem with the disconnector and it would shoot doubles, then jam with the bolt part way forward. Disconnector spring was too weak. Either your trigger group is damaged or something is binding.

It does only stops once the mag is empty.
 
Do not fire your rifle again untill this problem is fixed. This could be very dangerous, as much fun as it is! As much as it could be a trigger group problem, it very well could be a bolt/firing pin problem. If it fires before the bolt is fully locked, thats 55,000 pst coming back at your face!!!
Get it fixed.

were you holding it tightly to yourself? maybe bumpfireing?

handloads or factory?

new gun or used?

is your fireing pin floating freely?

take your bolt & carrier apart and clean it well

put 1 rnd in your mag charge rifle REMOVE mag and fire is the hammer forward or back?



replace the trigger group with new parts

It was factory loads.The gun is used
Im not sure about the firing pin but i will give it a good cleaning then go from there.
 
Your firing pin is probably binding. I had a tavor once and it would send off a few each time, and it was due to the firing pin expecting to him the hard primer of the military rounds. They did fix this though. If yours is dumping whole mags something is definitely broken and not just dirty, me thinks. I can see how that would be unsettling if you are not expecting it.
 
Swing the upper way from the lower on the front pivot and examine the operation of the trigger group. Don't let the hammer strike the front of the lower receiver. You can catch it with your hand. See if you can hold the trigger down, drop the hammer, and without releasing the trigger, push the hammer back rearward and have it catch in place. Now let go of the trigger and it should still hold the hammer, but you should hear it drop onto the sear. If it fails this test, there is a problem with the disconnect.

The other posters have good ideas about checking out the bolt and firing pin. And not firing the gun again until you know what went wrong. You should be able to move the firing pin freely back and forth with the bolt out of the upper. If you don't know how, there are good tutorials on youtube for how to tear everything down and reassemble.
 
Soft primers or primers not seated properly. Free floating firing pins can do this. I watched a guy slam fire a 30 rd burst with one #### of his rifle.(old days)
 
A run-away AR. That's awesome (and not at the same time). I would have to say there is something wrong with your sear. It could be defective, as in, not built to design specification (error in manufactoring?). Due to high percision machining required to create the small complex parts that make up the trigger/firing mechanism, just one part being off by a couple micrometers will make all the difference in the operation of your AR.
Afterall, one of the smallest parts, the firing pin retaining pin, is the only thing holding the weapon together as a firearm, lol. :D

Without it, your AR is just a fancy, expensive but less-effective club....
