I’m debating buy a cheapo 350 legend single shot rifle and a cheapo scope or get a decent ar-15 in 350. I’d much rather get an ar-15 in 5.56 when I get one but all I got to hunt local with my kids is a 12 gauge 870 and that’s too much for them. Does it nicely transition back to a 5.56 upper if I want later? I mostly want an ar-15 to shoot for fun at distance sooo I might be disappointed.
