Just got my first AR last week and took it out in the woods to shoot with a buddy yesterday. It works great, sights are just about dead-on straight out of the box and I'm really happy with it. My only problem (and it's not really much of one) is that when I tried to bump-fire it (yea, I know, but I wanted to try it once), it wouldn't make it past two rounds before it would FTF. It chambered a new round, but wouldn't go bang because the hammer wasn't cocked. I disassembed it and made sure the gas rings were staggered and they were. Any idea what could be causing this? It's not a huge deal to me because the gun works beautifully if I use it like it was intended, but I'm mostly just curious as to why it wouldn't cycle properly. |
I have had the same problem a few times. I think it was because I was hitting the trigger to fast and the hammer would ride the bolt back into battery. This causes the firing pin to not strike the primer hard enough. If you manually charge the bolt and ride it back slowly with the CH you will find that the hammer will fall(if you pull the trigget) about 1/2" to 3/4" befor ethe bolt has returned to battery. . I don't care. Bumping can be fun.

Try using the rubber band method. Loop a rubber band around trigger, then pull it in front of the magazine well, then pull it back and loop the other end on the trigger on opposite side. For the record I have never bump fired but am curious to see how this works. |
It was "generously lubed" as defined in the army field manual, but I think yall are probably right about the hammer riding the bolt back to battery. That makes perfect sense. Thanks for the help. |
