For curiosity and budgets sake I've been thinking about trying out some fixed power scopes. As these would be used for a truck gun(s) and hunting, looking at 6x or less although strongest interest is in 4x or less. Calibers involved would be .22LR, .223, 7x57, .308.

What brands/lines of used fixed power scopes would you recommend with an eye towards clarity and ruggedness? A good low light reticle wouldn't hurt either.

Thanks
Jeff
