As I understand it (from Bob Dunlap . . .master gunsmith) when an AR bolt carrier cycles backwards, the hammer is cocked and temporarily held by the secondary sear system. Upon completion of the loading cycle, the bolt closes on a new round. The operator would then release the trigger allowing the hammer to fall from the secondary sear system to the primary sear system in preparation for the next shot. What happens if the secondary sear system is removed? Assuming the trigger is held, would the hammer not fall forward again on its own creating a fully automatic rifle? Again, just curious if my logic is correct. |

Usually the hammer will follow the bolt forward and not fire a round in a .223 AR 15. If you have an unshrouded firing pin, the firing pin might hang on the hammer, jamming the bolt. If you are really lucky, you might cause an out of battery discharge. With the correct pistol caliber upper and high velocity rounds, you will destroy your gun. If this happens with a .223, you might lose an eye. Just say no. |

Disconnector. That is the term. There is no sear in an AR-15. And if you remove the disconenctor, the hammer will ride forward with the bolt, and put a light dent in the primer. It will no detonate. You will have the hammer down on a live round. EDIT.....beat to the punch. |
Not possible on the AR platform. The firing pin is too short to reach the primer unless the bolt is locked up and in full battery. The total JAM UP or light firing pin dent are the two potential outcomes of this criminalistic endeavor. |
Hmmm... I'm not familiar with the bolt group/set up of the pistol, and I don't know what a shrouded firing pin is but.. 1. the AR pistol is retarded 2. bump firing is even more retarded. - combine 1& 2 and forget it.  But that aside, on the AR rifle bolt group, you can hold the assembly in your hand. Then push the firing pin forward with the bolt unlocked or partially unlocked. The tip of the firing pin won't poke throught the firing pin hole on the bolt face. Only when the bolt has rotated and locked up in the extension will the firing pin be phisically cabable of touching the primer. Again... I don't know how this works on the pistol nonsense. |
| Full auto fire is wastefull and very inacurate. Ill admit it is tempting, i mean who wouldnt want one that fires full, semi, burst. But really, do you think youll take down more bad guys with full auto before you run out of ammo and or have to reload? Just forget it and practice with the semi auto until you get good enuf that full auto seems redundant. |
The hammer will go forward just like the hammer does on a DAO pistol. But since the trigger on the AR is single action you'll have to manually cock it each time. IOW, the shooter will get a lot of practice at malfuntion clearance drills and a lot of ammunition will be wasted since every other round will be getting ejected unfired when you cycle the action to cock the hammer. |
Both assumptions are totally innacurate. Someone who has trained in the proper application of automatic weapons will tell you that is has it's place. If you are trying to gain fire superiority it is ESSENTIAL!! Also though proper trainging auto fire can be accurately controlled. We are not talking about mag dumps. We are talking about 3-9 round bursts in a controlled manner unless you are attempting to unass the area. Then it dosent matter if it's accurate because all you care about is getting thier heads down and getting them to stop shooting. |
