It's as solid fiberglass package bow, that have been sold in Hardware, General, Sports & Box Stores, for years. They usually came with a few arrows, arm guard, glove or tab, cheap quiver, and a target. If you had it in its original unopened package, it would have collector value...
That being said... They are virtually BOMB PROOF!!!!! Years ago, my Dad ran over mine with a tractor... I shot it for several years after that!!!
They are good for kids, bow fishing, and just plain knocking around fun! As for the weight? Idk, all I can suggest it scale it.
