Just because it is a two piece tube doesn't mean that it won't hold up. Actually, unless a maker advertises that it's scopes are one piece tubes, they'll be made from at least two. The older Leupold Vari X II's have a sterling reputation for durability, yet until recently, they were 3 pieces. The objective, the tube and the eyepiece were separate parts. I've never used a Legend, but I've read several positive reviews of the scope, especially for the cost vs quality. I think that it'll hold up fine. Besides, it has a lifetime warranty on it.
