Hi everyone.wanted some input on a lightweight hunting scope for my son’s first hunting rifle.purchased a winchester xpr 30-06 from a buddy.it’s going to be my son’s first hunting rifle.up till now he has been using mine.looking to keep this in the $400-500 range.after using my rifle with a Leupold vx6 he really wants a illuminated dot.40-50mm objective.lightweight.has to be good in low light.300yds is all we usually shoot.i would love to get a new vx5hd but that is almost double my budget.was looking at a Trijicon tr20.there around $500 but have no experience with them.any and all info appreciated
