As Levy78 says, everyone should be well stocked by now or learned to reload and cast.

That said, there are still ARs available.

Don't discount bolt action rifles, shotguns and .22lr.

I you're late to the game those are all very viable options, with ammo still available and will be sufficient in the vast majority of cases.

great point, Eagle6. There are great calibers that are less subjected to the buying sprees like .270, 30-30, 30.06, etc. that are widely available in bolt action or low cap old tech autos loaders like M1 Garand or lever action models. These are proven and superb calibers and rifles. Dated but effective. If I were just entering the hobby, I would focus on these effective and, importantly, available options.
