hmmm, he must be aiming for the L96 looks, not the platform.
The MB08 is a solid choice, but as Reliku said, it's way too heavy, specially for a 13yo. It weighs 4Kg / about 9 pounds. But anything in that sort of look will be about the same or heavier.
If he's open to consider other looks (as I know how boys can be with that sort of thing...), then I would suggest something in the M700 / VSR style.
A JG BAR-10 is 2.7Kg / 6 pounds, and you can get a (sort of) pre-upgraded one with the scope for about $130, including the scope.
It makes for a much more effective gun on the field, so he'll enjoy it a lot. And it's the best platform for upgrades, if so desired in the future.
