Does a Bump Stock Allow a Gun to Fire 600800 Rounds Continuous Rounds Per Minute

Quoted: This, I remember one or two videos that easily were over 1000rpm Quoted: Quoted: I'll see if I can find it. This, I remember one or two videos that easily were over 1000rpm I'm curious how the accuracy is compared to the real deal? I recently had the chance to take my 6920 out with a select fire lower and was pretty shocked at how accurate I was. Standing, firing at a target 100yds away I was able to keep it pieplate accurate, which to me was pretty great. |

You lose accuracy once the rattling begins with any full auto. An experienced shooter can easily control a bump fire gun. |

I gotta admit I thought mine was going to be all over the place, and I can say that you do not want to be 25 yards away from me when I turn that thing loose. I haven't tried it farther than that yet, but at 25 a man sized target would take the majority of them. |

It seems most guys are using one that goes on barrel rather than quad rail or tube? |

It will depend on the rifle, ammunition and your technique. Mine normally is pretty steady around 750rpm but with 5.56 ammunition I often run just under 1000rpm. If you want faster cyclic rate get a LW carrier, carbine gas, xp main spring, short reset trigger and remove excess play from the bump stock. I have a JARD single stage set to .06" reset and my stock can only travel .2 inches. I have a rifle gas system on mine. |

Quoted: Quoted: What would be a good bipod to use? It seems most guys are using one that goes on barrel rather than quad rail or tube? I use a rail mounted GG&G bipod because I like the way it looks. Any decent quality bipod will work. ETA: A loose bipod may be more important with a longer reset trigger, I have no issues with a tight bipod. |

The bump action of the stock absorbs a lot of the recoil. In my limited experience I would say the bump stock was much more controllable than the real deal. |

I wouldn't think it would be as easy/quick to start stop as a real MG though. |

Quoted: I wouldn't think it would be as easy/quick to start stop as a real MG though. With the stock extended I place my left hand against the charging handle and grab the stock tightly. To begin firing I place the tip of my finger on the finger rest and then squeeze back on the trigger when I want rounds to start. When I want rounds to end I release the trigger. The rifle recoils into my left hand, compressing the meat of the hand. The hand expands back to it's normal position tripping the trigger across my finger. It just runs. |

I don't have an exact answer 10mm, sorry. |

Average is between 730 and 900, which is the same as the cyclic rate of a real deal M-16/ Transferable. Really light guns using 5.56 can get at or over 1000 rpm. I measured the RPM of a lot of peoples builds with an audio analyzer that turned out to be very accurate. |

Quoted: I wouldn't think it would be as easy/quick to start stop as a real MG though. It is... since all you have to do is the exact same thing... take your finger off the "trigger" (finger shelf). |

At least for me it feels awkward. |

Video up |

I think it was probably picking up some echo. You should shoot it again out in the open. |

Mine was around 850-900rpm with a Slidefire and 2lb trigger. |

I pull the audio from my video, depending on how good your mic is you may be able to see the peaks from rounds going off and compare it to the time taken to calculate RPM. If the audio isn't as good you can look at the first peak and last peak from the group and divide the time it takes by the number of shots-1 for the split time. Then use split time to calculate RPM. I normally see 750 to 977RPM. Tulammo always runs on the slow side. |

I took my bump fire stock for a test run at the range today. I forgot how much I don't care for automatic type fire. I will keep it as a novelty but probably won't use it much. Don't beat me up to bad. |

I normally see 750 to 977RPM. Tulammo always runs on the slow side. Regardless of how many shots it picked up, the time from the first shot to the last shot should still be correct. So taking the RPM shown and correcting for 2/3 of the rounds fired should be accurate. That M&P has a stock trigger which is 7+ lbs. |
