Hi guys, new mossberg 464 owner here from new zealand.I received my new 464 yesterday after buying online from a dealer here in new zealand.As i have nothing to compare it to i was wondering if other 464 owners could answer a question for me.The rear sight folds foward as you all know, but it has a heck of alot of movement, to the point that it wiggles up,down and side to side quite a bit.Is this normal? or is there something wrong with my one? .It seems to me with this amount of movement it could easily shift poi.I went ahead and ordered a skinner lo-pro sight for it anyhow but i may send it back to the dealer to be exchanged if this isnt normal,I also read that some of the earlier model 464 had extractor problems, this 464 is serial numbered in the low 3000's so it must have been sitting in the shop for years lol i hope this one is alright, thanks alot guys.
