My conception of a predator rifle is accurate, portable, quick and easy to deploy, adequate cartridge for coyotes, with a bright, adequate field of view, adequate magnification, simple, durable, relatively lightweight scope. Mine is a Savage bolt .223 with synthetic stock and the barrel clipped to 20". Super accurate and really handles nice. I have a 3 X 9 on it now, but am going to switch to the K6.
