I have boxes of mags available and a range of BB weights, and can test with a certain combination or swap the included mag for a different one upon request. Extra mags can be included for additional cost. All guns are chrono tested before they are boxed up. I do not have a range so I cannot test hop effectiveness, accuracy, or effective range, but most are checked to ensure that the bucking is protruding to a reasonable level. All are checked and verified that fps is within a reasonable deviation. Please reach out if there is a particular concern with a particular setup that you wish to use.
