Scope for 5.56 Rifle

[Great-Kazoo]

What are people running for their AR 15 platforms? I have never ran an optic with magnification before but decided to run one of my rifles with a scope. Looking for a place to start.

Barrel length and twist rate, average distance you plan shooting, max you'd like to hit or work up? Factory or loading your own, bench, 3 gun, PDW? Place to start, as in get comfortable then go longer, or buy once cry once comfortable?

I like a 4-20 after putting 5-25's on the bolt guns, if i could i'd sell them and go 4-20 across the collection.

16 inch, 1/7 twist, 300 Yards, Not sure how far I can really shoot with an AR and a 16 inch barrel, factory load, mostly bench, and just looking to have fun, maybe see how long I can shoot with it, but not trying to be Chris Kyle.
