im not an expert but the guy who was trying to rush me out the door was... right? Just as i was handing the guy my money i noticed that the oring set i was buying was labeled "For tippman 98" instead of "tippman 98 custom." I looked him dead in the eye and asked him if the oring set was for my gun specifically.. the "98 custom" not just the "98." As he was taking my money from my hand he looked right back at me and gave me a vague yes with a awkward nod of his head.. later, i got home to assemble my paintball gun and the one oring i needed is not in the set i was sold and some other ones i dont need are... i had a feeling... thanks alot for taking my money, not caring, and kicking me out of your store so you could go home...
