After a weekend of shooting my Poly 305 i've noticed that my rear sight apature has become so lose and flimsy that i'm able to just pull it without much force at. I was going to scope it but i've decided i want to keep my 305 old school with some good after market iron sights. (save the scope for a bolt action) I've been looking around but i want some opinions of anything you guys have, had or thinking about getting. Cheers!
