How to Make a Sawed off Shotgun

Step-by-Step Guide

1. 1

   Step 1: Choose the shotgun you want to modify.

   Single and double barreled shotguns are often cheaper, but pump-actions and semi-auto shotguns have higher capacities.
2. 2

   Step 2: Decide on the length of the barrel.

   The barrel must be no less 18 inches (45.7 cm) unless you fill out the appropriate NFA forms and pay the $200 tax (at that point, after getting approval from the ATF, the barrel can be any length), while the overall length must be a minimum of 26 inches (66.0 cm).
   
   It is advised to err on the side of legality by having a barrel length of 18 1⁄2 inches (47.0 cm).
   
   Accuracy is only severely affected when over 50% of the barrel is removed.
   
   Often the best place to stop is anywhere after the hand-guard or magazine tube ends.
   
   Less length equals less weight and slightly increased recoil. , The metal is not hardened steel and will cut easily.
   
   You can use a hacksaw, bandsaw or a circular saw equipped with a suitable blade. , Measure the barrel to your preferred length and wrap some masking tape around the barrel.
   
   Measure again and make several marks on the tape.
   
   Connect the marks, making a line completely around the barrel.
   
   Carefully cut the barrel using the line as a guide. , Using a tubing cutter will result in a ridge on the inside of the barrel, this ridge should be filed smooth. ,, A stock allows the increased recoil to be controlled more easily.
   
   Keep in mind that the overall length of your modified shotgun must not be less than 26 inches (66.0 cm).
