I’m surprised so many folks are recommending low power scopes for a rifle that will be used for paper punching. I’d look for something in the 4–12x range. And I would buy anything without an adjustable objective for shooting paper. Pick whatever brand and model is within your budget. I’ve had good luck with Leupold and the Bushnell Elite scopes. The Vortex’s I’ve tried seem to be good scopes for the dollars spent.
