You can get .308 AR models for under $1000.
Sounds like a great set-up. 308 is potent medicine for hogs. I’m invested in the 300AAC though. Have to be more selective in your shots but it will do the job. I have taken several white tails out to about 100 yards with and without suppressor. It uses standard 5.56 mags and is much lighter than the 308. Ammo is about the same price and I have access to a good selection of commercial. Roll my own to. It is my general use centerfire hunting rifle and self-defense carbine. Sold the rest of my AR’s. Used the 5.56 in and out of the service. Played with the 6.8. Settled for the 300.
