Hiya, thx for thread, and bummer it drifted off. Like suggested a non marring tool, may tap right back,I'd found a 3 buck mini mallet in arts crafts wall mart with rubber and plastic ends for such jobs. Czc sells a sight pusher for 90bucks and imagine a LGS would not need 5min ta straighten ya out. The red/blue loc-tite I've used all dried up and crumbled away a few range visits, so good luck. Be well.
