I have a PredatAR 7.62 with a 16" barrel and want to change the muzzle device.
Was Rocksett used on the muzzle device? What is the torque setting on the on the rail hex screws? Do I use Locset when I re-install the screws? Thank you |

I needed to swap out the muzzle device on my OBR 7.62 before I pulled the trigger the first time. I bought a golf club rubber shaft clamp and split it so that the OBR barrel fit. I then tightened it down in my shop vise and removed the factory muzzle device. I had previously removed a brake (different gun) that was installed with Rocksett and expected the Larue factory muzzle device to be difficult to remove. It came off considerably easier than I had expected. The rubber shaft clamp was a $3 investment and it allowed me to install my QD adapter with no fuss.

Good tips, and to my understanding, Rocksett isn't any tougher to "break" loose than blue loctite. Just holds up to the heat. A.W.D. |

I tried the gorilla method and could not get the device to spin off. I researched the topic and found that if you soak the muzzle device secured with Rocksett in hot, soapy water overnight, the Rocksett dissolved to a point and the device was easily removed. |
| Rocksett is supposed to standup to roughly 2000 degrees F, IIRC, while blue locktite is somewhere between 250-350 degree F. The blue locktite will require more torque to break than Rocksett which requires roughly 30#s. Surefire ships their devices with Rockset for the heat resistance, not the torque resistance. |
