I thinking ahead about what irons I want to go on a new build, 16" barrel, flat top with 10" handguard. Deep inside my spare parts bin are a set of UTG flip ups from an old abandoned 22lr project. I didn’t pay much for them and wonder about their durability and accuracy. I don’t want cheap sights on this build so I was looking at other options. I’m not against fixed irons but eventually want to put an optic on this so flips are needed, Id have to be shown some setup with fixed irons that allows me to use an optic to be convinced. some questions: How well do the flips hold zero, even the good ones? Is this an issue? Whats your honest opinion of UTG? don’t hold back if you think they are junk... Whats your opinion of the best flip ups to buy?
