[ARCHIVED THREAD] - Geissele super duty meltdown autopsy now with HBAR and URGI NEW GFR 6 arc at 1,000 yds video! (Page 6 of 7)
|
Quoted: Have there ever been reports of an AR based rifle failing due to gas tubes or sustained full auto fire during actual use of the weapon outside of a guy with a glove mag dumping them for clicks? I can’t think of any. Doesn’t mean it hasn’t happened, but… @Marksman14 Yes, may not be the gas tube but multiple M4s failed at Waynat due to the heavy rate of fire. Full-Automatic Fire and Weapon Stoppages At Wanat, the weapons were pushed to their limits and beyond. In the Combat Studies Institute's paper, historian Cubbison attributed the weapon stoppages experienced by Wanat's defenders to their necessity to fire their M4 carbines at sustained high cyclic rates. This conclusion is supported by the CNA study, which revealed that Soldiers firing weapons on full-automatic doubled their probability of experiencing a stoppage Rounds per Minute According to U.S. Special Operations Command's SOPMOD (special operations peculiar modification) program office, "The current sustained rate of fire for the M4A1 Carbine is 15 rounds per minute and a maximum rate of 90 [rounds] per minute for short periods in an emergency."18 Firing the M4 carbine at cyclic rates of fire of 90 to 150 rounds per minute, "which is the rate of suppressive fire associated with machine guns" for prolonged periods leads to rapid heating of the barrel and possible failure |

Quoted: Hey @sagmill are we going to get an autopsy of the URG-I? Also, could you tell @gacs to check their PMs?  Hello Tobysi, we sent a swag pack out a while back. I will check with our shipping team and follow up with you. We will be happy to talk to our marketing team about the URG-I meltdown. We are currently working on some awesome content with products that are coming to SHOT Show. More information on things like HBAR, King Hunter, GFW, etc. |

Any news on the package and any news on the possibility of a URG-I autopsy? |

Kinda want the upper off that PDW. |

Quoted: Q: why hasn’t anyone come up with a better gas tube? Heavier weight, or with radiating fins to dissipate the heat faster/better? I know we’re talking freaking superhot jets of gas here, just curious. I’ve seen other meltdown videos and that’s the place that seems to fail first in the better quality AR pattern rifles. Have seen M16's at Knob Creek MG shoots have glowing red gas tubes a few times. One guy was mag dumping 100rd Beta mags one after another. |

Quoted: That upper in 300BLK would be sick. And I’m not even a 300blk guy. Not interested in adding another caliber. I have a 57.5 SBR now and it’s easily one of my favorite rifles. Putting G$ upper on it would be awesome. I’d end up SBRing a few more lowers. I’m still counting down till the super heavy 1633 MG upper comes out. |

I’m still counting down till the super heavy 1633 MG upper comes out. I get that. I just don’t know if I’d care for an 8 inch 5.56. 300BLK on the other hand would be perfect out of an 8 inch barrel. |

Quoted: Yeah. My Geissele uppers in 5.56 are amazing. Dont feel like getting weird cartridge guns. Quoted: Quoted: I have cartridge fatigue. Yeah. My Geissele uppers in 5.56 are amazing. Dont feel like getting weird cartridge guns. They're definitely neat. But if I can get hits with 5.56 beyond the effective range of the cartridge (with a Geissele setup) then at that point I'm chasing a Practiscore title, which isn't my goal |

But not enough to get me to adopt a new caliber I wish I’d have taken 6arc seriously sooner. I was saying the same thing. Then I started reading up. Turns out it’s awesome. It likely would replace half my 5.56 precision setups if I had a re-roll, and when it’s time to rebarrel that’s what a lot of them will get. It gets you large-frame ballistics in a small-frame package. It’s such an efficient round and absolutely sails to target. It makes wind and elevation calls very forgiving. |

Quoted: Isn’t magpul making a new 6arc mag? Yes, but it’s for a different magwell dimension based around the LWRC six8. The Surefire ICAR uses the same dimension. The Duramag 6mm/6.5 Grendel mags have been flawless for me, and the Alexander Arms mags are good too if you’re using a standard AR15 lower for your 6 ARC. |

Yeah 6arc seems to be having a bit of an identity crisis with the new magwell. I’ll say my Duramags have been great in Grendel and arc in general. I’ve got a Geissele 6arc mag but I haven’t even gotten to using it yet, the duramags work great and are a fraction of the price. |

Quoted: It's totally awesome. I would never argue otherwise. But I still have cartridge fatigue and just because it's awesome doesn't mean I'm buying I’m in the same boat. There’s such thing as too much. I’d love to play with the new caliber, but I’m well pat my limit. Doesn’t help that inflation is eating up my spare funds. I’m not one of the arfcom multi-millionaires. |

Lead engineer mag dumped a pmag in a mini IPSC The new PDW has some new gas system. Same thing??? @whiskersthecat That phased array gas system actually sounds ingenious and may be the best thing to come from all this. It’s literally for three gas ports that push in sequence. They’re even matched up against the rifling is memory serves so you don’t get any issues from drilling into the wrong part of the lands/grooves. |

As far as I remember I saw a video stating the three gas ports are aligned with the rifling. I know all three are different sizes. |
