  • 6026 T9 Aluminium
  • 14mm CCW Thread
  • Larger Through Bore

A 14mm CCW threaded outer barrel for TM MK23 NBB gas pistols which lets you use more common suppressors on your MK23, without the use of a thread adaptor.

Full description


This outer barrel replacement for the TM MK23 SOCOM features a 14mm CCW thread on the end, which allows you to use suppressors other than the one originally supplied with it. You could achieve the same effect with a thread adaptor however that will result in a gap between the end of the pistol and your suppressor, where as this replacement outer barrel will let the suppressor sit closer to the end of the MK23. This outer barrel also has a slightly wider bore than standard which means you are free to install longer/uprated inner barrels for increased range and performance. Three O-Rings are supplied with the kit to help stabilise aftermarket inner barrels. Only one needs to be used however all three can be used at once should you wish. Outer barrels with a diameter of 8.1mm or less may not be supported well by this system.

The outer barrel is manufactured from Aircraft Grade 6206 T9 Aluminium with machine cut threads and a black anodised finish. The higher quality materials mean that the outer barrel can achieve a much more secure clamp onto the HOP unit, and care should be taken when securing the outer barrel in place so as not to strip the thread. The manufacturer recommends the use of a thread protector when not in use, so as to protect the threads especially during transit. Please note that this outer barrel is for the TM branded MK23 only and not ASG or other brands.

Size guide

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.

If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
