Full description


This barrel extension is perfect for rifles that you want to add a suppressor to but can't because of a barrel that is recessed far inside the rail. Or maybe you had a sunken suppressor look before that you're tired of and want to relive the glorious 90s look where the more barrel you had poking out your weapon the more operator you were. There are five variants of this barrel extension available: Type 1 is a standard M4A1 outer barrel, with the remaining versions being variations of a straight barrel extension.

  • Hides extra inner barrel slack
  • Adds space for quick detach or other barrel accessories
  • Helps add suppressor/tracer to a barrel recessed inside rail
  • Extend overall length of your weapon

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.
