Maybe not insane, but certainly irrational. Sure, replace them all if it makes you feel better, but I doubt it will do anything beyond the feeling. Never heard of an issue with any of those t3x parts aside from people over-torquing the bottom plastic (if mim is metal that isnt the bottom plastic), and never had an issue with any of these other parts on the tikkas I’ve owned or been around. The very few issues Ive heard of like above involve high round count guns—like many, many thousand rounds, and even then uncommon.
Imo bottom plastic (and the stock) is the one part it makes sense to replace if you want to torque the action screws tighter. There are several options for that, I like the high desert bottom metal. But imo most of the aftermarket replacement parts exist because of the original t3 version, which have all been addressed. At this point it’s snake oil.
