Review: Does what it is supposed to do. - I screwed something up the first time so I had to re-do the application for my Rearden mount to my pew. Worked like a charm when after making sure the threads were clean of oil and let it set for 24 hours! Highly recommended. Review: The winner is Rocksett!!! - A little dab will do ya! Use this on gas blocks and muzzle breaks if you want the best thread locking retention method. Rocksett is a superior method that can handle high heat application. Don't even think of using Loc**ite 242 or 271 because they will not hold up under the heat.
