Guns, Dogs and Blades QnA

So ,
I am not sure if this is where I should post this but I am in the market for a decent
4-12 scope for a deer rifle.
It is a Remington model 7 in 6mm rem.
This gun was a great shooter for me 20 years ago, been in the safe since.
Been hunting with 30-30 since but I need to call long distance.

This Rifle is dependable to kill pies at 300.

Please advise, All ears
