Ditch the bipod. Use a rest on a bench, and use shooting sticks or your pack in the field. Bipods have a tendency to bounce on a bench, and in the field shooting off your pack works great unless you need to get up high, in which case the bipod is useless, and you'll need to use the sticks, anyway. You'll get tired of lugging around the bipod.
The Butler Creek scope caps are fine, but they break somewhat easily. But they're cheap, so it's not too bad.
