I'm in the minority. I voted to ditch the AR. They aren't really any more versatile than a shotgun, shotgun ammo never disappeared after Sandy Hook like 5.56/.223 did, nor did the price go up substantially. You'll never have an AR setup that will hit as hard as 12 gauge slugs. Flite Control isn't cheap but it's the best alternative for Buckshot. Yes splatter gats take more work to run well. So what? Sell the AR, set up a 1301, get some ammo, and take a class from @jlw.
