Not as accurate as other barrels
only one tip
I have tested this marker in my backyard with about 1500 balls. It was more accurate than my stock barrel but not so much as to make this a great product. It gets about 12 inch spacing using it on a Spyder Electra, and that I thought was pretty good. I haven't used it on my Shocker yet because I need a barrel adapter.
If you want agood but not great barrel kit that is also cheaper get the Empire 7 Piece barrel kit
