Hello I'm new here and relatively new to paintball. I have just bought a Tippmann 98 custom and have a quick question about the screws used to hold the gun together. I bought the gun used so I didn't get the Allen wrenches that should have come with the gun, and I've tried all metric and standard hex wrenches that I have. Does anyone know what size (and what kind) of tool is needed to turn the screws? All the wrench sizes I have are just a tiny bit too small or too big, and are begining to round out the screws. Sorry if this belongs in the New Player section.
