My son is turning 12 soon and has shown an interest in shooting more. He’s had his Crickett since he was 7. I’m looking for a bolt .223 gun that he can grow with. Budget is not a concern, per se, but I don’t want to spend thousands either. I’m looking for a “bang for the buck” type setup. I already have the scope. Would like adjustable length of pull and comb/cheek riser. Something I can easily put a bipod on. Recommendations? Thanks!
