The adjustable stock and tube assembly is an awesome upgrade to the already phenomenal Stormer! Look and feel of a real AR system rifle. Only reason I'm not giving 5 stars is that the set **** didn't come with the package. Had to head on over to the local hardware store to find the right one. 15 cent thing to truly make it a "ready to go" package would've made the difference. Other than that, glad Tippmann offers this upgrade to the Basic Stormer.
