Trying to find your serial number for a warranty RMA or Rebate form?
You can find the pistol, rifle or lower serial number engraved on the lower receiver. Depending on which model you have purchased, the serial number could be on the left or right side of the lower receiver. The serial number will start with a letter followed by multiple numbers.
You can find the upper serial number on the inside edge of the upper receiver. Please disassemble your upper from lower and turn upside down to locate the serial number. The serial number on current models will start with PWS followed by multiple numbers.
