I was tightening a 51t brake onto my bbl and I thought It was straight so I applied the Rocksett, too bad I was wrong. How do I remove this stuff? (please don't let the answer involve my bandsaw  ) |

Are you trying to just get the mount off or do you already have the mount removed but need to remove the remaining rocksett from the threads?
I have personally found that Rocksett isnt really all that strong of an adhesive and that it doesnt really take a whole lot of torque to get a brake/hider off that has been Rocksetted on. Its not like a high temp solder or anything of the like. I have removed the most stuck flash hiders by turning the gun barrel down and soaking with a penetrating oil like WD40 over a week or so, just go into the safe and hose down the barrel and break and let the penetrating oil seep into the thread area, just keep the barrel in a plastic cup. Every couple days pull the gun out of the safe, mount the barrel properly in a vise, and apply a reasonable amount of torque. Usually after a couple days of marinating in penetrating oil most any break/flash hider will come off, Rocksett or not with a little pressure. You also know how much torque you used to put it on so you have a good reference point as to how much leverage you should need to apply to get it off. If you already have the break off, than as a previous poster mentioned, just use a brass of stainless brush and clean the stuff off the threads as it is fairly brittle. Good luck and let us know how it goes. |
| You shouldn't need any kind of penetrating oil. I took my AAC Blackout mount off by clamping the upper in a vise and homemade vice block (wood) and wrenched it off with an open ended wrench (24mm I believe). It comes off with just a little more torque than removing a standard A2 with crush washer. I would suggest using a barrel clamp instead of an upper receiver vise block so you don't flex the upper receiver. |

I used the Rocksett that came with the AAC flash hider mount. I wanted to change the style of the mount on that barrel. The mount didn't want to come off. I stripped down the barrel and put it in the freezer. It ended up being in there a couple of weeks. I planned to pull the barrel and the aluminum vice blocks from the freezer. Then I would warm the mount with a MAPP torch. I clamped the barrel into the vice blocks and sized the 12" adjustable I was planning to use. I wiggled the wrench in the tighten and loosen direction as I snugged up the adjustment of the wrench and the mount broke free. I've done this now, a couple of times. Put the barrel in the freezer and the Rocksett will break loose pretty easily.
