Ogden, Utah • A Utah man has lost an appeal of his conviction for illegally making and selling more than 1,400 machine-gun converter devices for AR-15-style rifles.
The Standard Examiner reports that Scott Ray Bishop had argued that he was wrongly blocked from offering expert testimony about his converter kit, which he said was for educational purposes only.
The 10th Circuit Court of Appeals rejected that argument on Monday, leaving Bishop to continue serving a nearly three-year prison sentence that began in May 2018. The judges ruled that Bishop damaged his own case by not complying with federal criminal court rules of procedure when he represented himself at trial.
An attorney representing Bishop on appeal did not immediately return a call seeking comment.
