Attachment instructions:

 
Prior to use of the A12, the choke must be mounted correctly in the silencer.

  • Check that the two front screws and two backend screws are tight and that there are no foreign objects inside the silencer.
  • Check that you have the correct choke by trying it gently by hand in your barrel.
  • Screw the A12 choke all the way to the bottom of the threads in the A12 silencer.
  • Firmly tighten the lock nut with the supplied tools.
  • Screw the A12 silencer with choke attached on to your barrel.
  • Loosen the check nut.
  • Adjust the silencer to desired "clock" position.
  • Tighten the lock nut.

 
Dismantling for cleaning:

  • Unscrew the two screws on the front end of the A12 silencer with a 3 mm hex key.
