Quote HistoryQuoted:  I'll be sure to take extra care when I mount the flash hider on my Noveske SS 11.5. A flash hider is easy since you aren't timing it - just tighten to torque spec and call it a day. With a brake, you might be tempted to crank on the muzzle device in order to get the ports in the right direction instead of taking the time to find the right combination of shims. |

You are right there as well, and that is usually a problem in softer materials like aluminum. I've spent some long nights on the shop floor helping do some risk assessment for products built incorrectly or that exact reason. I'm sure Noveske has some pretty capable folks on staff, so looking forward to their report. As am I. Aside from the rarity of the failure it just *looks* weird. |

I see this a lot on o2 sensors on cars. A slight thread issue mixed with heat and time and this is what happens on the pull out.

well the torque was too much, 40 lbs would really be cranking it... I have gone as low as 10 lbs on precision setups and just used a healthy dose of fresh Rocksett, not the hardened tube of crap that comes with the mounts.

Quote HistoryQuoted:
Have seen this only when someone over torques the muzzle device during installation of it. Those mounts are harder steel than the threads, once over tightnened the threads are whats gonna give way. Plus the thread looks intact where the thread relief is on the mount, further making me think this is what might of happened. |

It may be high in terms of typical muzzle device installation which often use a crush washer or other means to establish the right thread loads, but shouldn't be anywhere near the yield strength of fine threads on a stainless steel barrel. If it was a standard screw of the same thread pitch and material it would actually be right in line with a typical torque spec. Threads need a certain amount of stress to actually "lock." Too low and they will loosen with out the aid of something like rock-set or other thread lock, and too high and they will yield and fail. |

Torque specs for 5.56 mounts in 1/2-28 are 20-30 ft/lbs.
Torque specs for 7.62 mounts in 5/8-24 are 45-55 ft/lbs.

How in the fuckballs do you rip threads off? I have never seen that before.

I understand that different threads need more torque, but I wouldn't tighten anything on a ~.30 or small muzzle to 45-55 ft lbs.

No Way.
Looks like a pinned/welded flash hider was wrenched off and the weld ripped the treads out. I have seen this happen in person before with a DD flash hider that the person did not know was welded. |

That could be taken as an admission the threads were too thin, or it could be taken as superior customer service....
Hmmm... Maybe both. JPK |

I'll take it as both. Not sure how it happened but it was an excellent and accurate barrel up to this. Noveske has always done the customer right and I see that continues even after Johns passing.

Anyone have issues with short lightweight barrels and major POI shifts between suppressed and unsuppressed? I might replace it with a lighter barrel while I have it apart anyways. any time you change harmonics by adding weight etc youl most likely get a poi shift. a stiffer/heavier barrel will minimize some of that. this is just my experience |

I removed the muzzle device from my KAC SR-15 upper (because after paying for the upper I can't afford KAC cans!) and while I really cranked on it (using the KAC reaction rod/cattle bludgeon) without result when dry, after soaking overnight in water it gave up with a sharp crack with less than a quarter as much force as I was applying the day before. No idea how much was on there, but night and day difference in removal effort. |

That would be my guess--- Good customer service, and easier faster for them to just replace it rather than deal with any weird research into why or all that. But you're on a post saying "They are taking care of me" rather than "Screw these guys, they won't replace my barrel." That in itself is worth some money in advertising! |

It's been a while...but again installed as per the instructions so 20-30...I usually split the difference so likely 25 ft/lbs. Did you soak in water prior to attempted removal? Water and after it wouldn't budge PB Blaster behind the brake with the upper pointed muzzle down...reapplying every couple hours until it finally broke free. I've got three devices installed with two drops of Rocksett each. Just want to know what I'm in for if I ever need to remove. |

You're right...and I would have been pissed if AAC or Noveske didn't help out. As it turns out, both are. AAC is replacing the brake and Noveske is replacing the barrel. No complaints from me... I hope to have the rifle back together by next weekend in order to go shoot some coyotes.... |

So I take back what I said about Noveske. I'm sorely disappointed and will not be buying their shit again. Gas block hole was under drilled or the pin they sent is over sized. It went half way in and now won't come out or go in. Bent 3 pin punches trying to get the pin back out. I'll drill it later tonight but their QC seems to be lacking if in fact the threads were shit...and now this issue.

Interesting New pin does not measure the same as the old gas block pin off of the barrel with the jacked threads. For $300+ I'd expect better quality that faxon or any of the other budget barrels out there that function just as well for half the cost. |

Drilled the pin (not easy...they're hard) and reinstalled the old pin from the last gas block. Frustrated I wasted 3 hours doing what should have taken 3 minutes. I'm ready for this ordeal to be over. Lots of work and waiting to swap a brake for a flash hider...

Rocksett is as aggressive as fingernail polish. I can never tell other than visually, when removing a muzzle device, if it was even applied. This looks like it was over torqued and the thread to muzzle device interface was lacking, and the result is obvious. Barrels are only about 28-32RC for the harder stainless ones.

Being stainless probably has something to do with it, but unless my torque wrench is way off then it was torqued to spec.
