A pal has a SIG Rattler Canebrake. Really cool pistol. It has a fake suppressor on the barrel. He has tried to remove it in anticipation of the arrival of his actual suppressor with no success. Is this attached with Loctite or Rock-set? He thought of me because he knew I have a heat gun that would breakdown Loctite. Can anyone confirm that heat would be the right approach to remove the fake can before applying a wrench?

They are not attached with any type of locking agent, just torque. It will take a significant amount of effort to break it loose. If you don't have a Bev Block or reaction rod modified for the MCX barrel extension, try clamping the gas block in a vise. Just be sure to pad the vise so you don't scratch up the gas block.

Thank You!
Put a full size 7/8" wrench on it and it did come loose. No visible loctite remains just very tight, likely due to taper.

Yeah, the taper lock is pretty strong. They say it takes approximately 3 times the torque to remove as was used to apply.
