What factors determine whether one buys the hollow version or the solid? Thanks again.
hes got it rightfubar said:cost is the same. so if you're trying to save a little weight or maybe very slightly change the balance of your rifle. i dont see it making a difference that i could feel.
from him i'd bet its strong enough so strength isn't an issue. the drive shaft on cars and trucks are hollow. so get which ever one you desire.
