I don't know why people always say Macroline doesn't last as long as steel braid. Granted, it's plastic and more prone to breaking, but I've had macroline on all my guns since the sonix and hadn't had one blow on me. I have the same piece I had when I bought my Shocker over a year ago (luckily it fit even after I bought the ASA and rail.)
I would however be a bit leery to use it with Co2, because I've heard the horror stories from it freezing and then blowing...
Ares is right though. It is just throwing a couple bucks out there if you don't need it.
