| I just picked up my new 7.62SD today. Do I really need a torque wrench to install the mount? |
|
Quoted:
It will come back off.................Rockset isn't a weld. I have removed mine more times than one. This^ it's easy to remove. Use acetone to clean both threads on the barrel and on the mount. Read instructions, make sure the mount goes up against the shoulder of the barrel. |
Before I got a proper barrel vise.

Quoted:
I heard it's water soluable....any truth to this? 24 hours in a bucket of water and it comes off. BTW- the cherry red AAC QD makes me cringe...... Now that I have a proper barrel vise block mounts come off with a combination wrench with a little effort. (No water needed) And why would heating a mount make you cringe? Heat treatment processes start at what, 850 to 1000 degrees? The heat put out by a little MAPP torch probably wouldn't get it hot enough to do any damage. |

Exactly, and heating it with a little torch isn't going to do anything to it either. Rocksett resists extremely high temps up to over 1100 degrees centigrade, which is exactly why it's specified for silencer mounts- it holds at extremely high temps that all the Loctites do not. But, it's got a low torque value so you can easily wrench it off for removal. |

If I'm reading you two correctly you say Rocksett is rated for 1100 deg F yet you're using a torch which you say isn't getting near that temp...unless of course you are at or over 1100 deg F. Take a look at this chart and see where visibile red starts and for your information the colors are charted in ambient like not dark........yeah you're easily over 1000 deg F. http://htsteel.blogspot.com/p/temp-color-chart.html I was just saying....it makes ME cringe, nothing more. The upper receiver is heat treated too....you going to take the torch to it? The thing that really must suck is waiting for the day when the suppressor doesn't mate up right and then ping....baffle strike or worse. |

Just so this thread isn't further derailed:
I posted a pic of heating the rocksetted mount because that is what I needed to get it off with the equipment I had at the time. I was just using wood strips around the barrel that did not have enough bite on the barrel to hold it stationary while I wrenched the mount loose. (it would turn in the vise) Now I have a proper barrel vise block that WILL hold the barrel enough to break the mount loose. I do not use any heat or water. And heating the mount will expand it enough to loosen it without melting the rockset. I put a screwdriver through the FSB with a wrench on the flash hider and it did not take nearly as much torque to break it loose after heating than with a barrel vise. |
