hello all, i recieved a 03-a3 from my grandfather when he passed and the wooren stock past the sling hook has been removed; to the bolt on top and from the sling point to the barrel on bottom. is there a way to scope this weapon without drilling? i have no problem shooting iron sights and will not destroy this rifle to shoot a scope. also is there anywhere i can purchase an original stock to replace what was taken off? thanks.
