  • Barrel thread length required for a SUS-TAC suppressor between 15mm to 20mm. If your have a thread which is not in this spec, please contact us for a solution.
  • Barrel thread should have a square shoulder to allow the suppressor to be tightened onto.
  • It threading is required, it is recommended that the thread be approximately minimum of 2mm smaller than the OD of the barrel. This allows a decent square edge for the suppressor to seat on. Beware that the thread must not be too small to reduce the wall thickness of the barrel to a value that sacrifice the strength of the weapon.
  • Accurate threading done by a competent gunsmith to make sure suppressor is concentric to the barrel bore.
  • SUS-TAC will not accept responsibility for damage caused by incorrect installation
