I have rifles for the everything going bad situations. Since that's the case, I'd rather spend $400 on a rifle and $200 per 1k rds of ammunition, rather that double that (at least) for an AR and even more for quality ammo... not to mention that in a bad situation the rifle might see some abuse and I wouldn't be able to clean it regularly.
So my preference is cheap and reliable... and accurate for the ranges I'm thinking I'll need. If it's beyond a couple hundred yards, I'd be hard pressed to prove it was indeed a threat to my safety
And I can use a PSL if I REALLY need longer range
AK for me. Only have one right now... need more....
