I built an XM177E2 retro AR a bit back, I shoot it occasionally and every time I do, within 100rds the hammer pin walks out and binds up my hammer being askew and all. I've oriented the pins both ways I can, but the problem persists. So, I installed a set of anti-walk pins from Rise Armament. They went in with zero difficulty, but now my hammer is sluggish, like its impeded, something is slowing it down resulting in light primer strikes. Light primer strikes are most notable on the first round after releasing the BCG on a fresh magazine, after manually cycling, I might get 2-3 light strikes resulting in a failure to fire out of 10 rounds. Problem is consistent regardless of ammo used. I don't think the anti walk pins are oversized, interfering with the hammer travel, I installed them easily with my fingers and a slave pin, didn't have to tap them into place, but it definitely doesn't move smoothly and free like it should. To be honest this is probably one of my only problems I've ever encountered of the sort.
