You need this for a custom rifle and quality scope - BlackHawk Scope Protector W/Padded Crown Black 62SP02BK

I use this in conjuction with the Blackhawk Drag bag. I know it might be overkill, but when you pay over $2,000 for a custom rifle, and $1500 for quality optics, a little extra padding is cheap insurance.
Pros: Nice padding
Cons: Takes a little while to fit straps to scope
