I haven’t, they are always as tight as you left them. I believe it was Greyfox on this forum that suggested the anti seize one time and I have came to like it. The thread locker for me has always just seemed to ball up at the top of the threads, and then there’s the old sayin of locktite use as being a gunsmith’s best customer.I also generally use a thread lock on the base screws. Have you ever had a base come loose with the anti seize. TKS
