  • CNC Machined
  • High Quality Thread
  • 12mm CW to 14mm CCW

A thread adaptor which fits into 12mm outer barrel threads to enable the attachment of standard 14mm counter clockwise suppressors, tracer units and other muzzle attachments. 

Full description


The adaptor is constructed from CNC Machined 6026 T9 Aircraft Grade Aluminium, making the part lightweight, accurate, and most importantly, highly durable. The threads are machine cut, making them highly accurate to ensure no damage is caused to the threads when they are installed. The thread is specifically designed to be inserted into pistols and outer barrels with a 12mm internal thread, to allow more common 14mm threaded Flash Hiders, Suppressors and even tracer units with ease. This is perfect for those Airsoft Skirmishers who have been looking endlessly for ways to attach Suppressors to their gun's internally threaded outer barrel.
