When looking to increase the performance of your AEG, a tight bore barrel is one of the best places to start. Most AEGs come stock with an inner barrel with a 6.08mm diameter. Replacing this barrel with a tight bore barrel (a barrel with a diameter of 6.03mm or smaller) will help to improve your gun’s accuracy. As an added benefit, the tighter diameter of a TBB restricts the air flow better, increasing FPS by a small amount. This aluminum barrel is Teflon-coated to withstand wear from BBs passing through the barrel.

This barrel’s 6.01mm diameter is extra tight for increased precision, but as a result, extra care must be paid to proper maintenance.


  • Material: Machined aluminum
  • Diameter: 6.01mm
  • 6.01 mm diameter provides better seal around BB
  • Teflon-coated interior to reduce BB wear
  • Increase range, accuracy, stability and consistency
  • Designed to produce tighter groupings at range

**NOTE** Double check the length of your airsoft rifle's inner barrel to ensure you purchase the right upgrade inner barrel.  The airsoft model types in the listing are examples of replicas that use similar length inner barrels for reference.
