Made popular by "Stitch", one of our video reviewers, this simple mod is a great way to dress your Tippmann marker with a professional custome look. The Blackout Sleeve snaps over your existing shiny steel braided gas line. This cover will turn the glare of shiny stainless to a hard plastic flat black. You can trim this hose to shorter lengths with a sharp knife and install it in seconds. An inexpensive mod everyone should have.
