This might sound goofy but a Hi-Point 9mm carbine is very reliable, relatively cheap and cheap to shoot. You have a wide range of ammo available that would take down any varmint out there..They are a blast to shoot and can be scoped..The 9mm out of a rifle is pretty quiet...you can still get a NIB one for sub $200...One of my ARs is a 9mm and I shoot it the most
