Nice rifle! The 6.8 will be great. I am still thinking about building a 6.8. Hmmmmmmm........
I like the 1X6 scopes that are out there right now from various manufacturers. I have a 1.5X4.5X28 Nikkon Monarch on one of the AR's for close to 300 yard stuff, and a ? (I forgot what I have on that rifle) 1X6X50 on the Remington 7400 30.06. That way, I can engage close to far and still use the scope. They work great with my growing older eyes!
