RE: Who uses iron sights
I do. The woods where I hunt are very thick. Lots of wild muscidine and honey-suckle vines to snag on stuff. 50yds is a long shot so no real need of a scope. I use a SKS which is post and notch but the front post is hooded which kinda acts like a peep for getting on quicker.
Last time I was at the local range a guy with an AR-15A2 with goverment sites was shooting vise at a can at 100yds. Before we was going to leave I asked if he minded if I shot his can. He laughed and said yes. 10rds 10 hits. Nothing wrong with irons but they do take practice.
