  • 6.03mm Tightbore inner barrel
  • For most Airsoft AEGs - Standard AEG barrel cut

If you want to squeeze a bit more accuracy and FPS out of your AEG, Laylax has just the thing. This 6.03mm Tightbore Inner barrel is part of the Laylax Prometheus range, widely regarded as the best source for AEG upgrade parts in the world. Inner barrels from this same range are known for their rigid stainless steel construction and immaculate internal finish and are what we use in the phenomenal Bolster Armouries AEGs.

This 6.03mm tightbore is designed for AEG rifles, SMGs, and support guns which use the Tokyo Marui AEG style of barrel cut, which is the vast majority on the market, and will provide an accuracy improvement thanks to its finely polished internal surfaces and a slight increase in FPS thanks to the tighter bore improving air seal and the overall efficiency of the system.

  • 6.02mm Precision barrel
  • Stainless steel construction
  • AEG Barrel cut - Fits most Airsoft AEGs

If you want to improve your AEGs accuracy, range and consistency, a barrel upgrade is a great start! The Specna Arms 6.02mm Steel Tightbore Inner Barrel promises to be an improvement even over stock 6.03mm brass tightbore barrels and its stainless steel construction makes it far more rigid and less prone to bends than other brass and aluminium barrels.

This barrel is cut for standard Airsoft AEGs and should fit most of them, though we suggest referring to the product description of your gun to find out what length you need. The standard AEG barrel cuts mean you can use this precision barrel with standard AEG HOP-up buckings, HOP-up nubs and HOP-up units, meaning all your existing parts should fit and plenty of opportunities to pair this barrel with other accuracy upgrades. If accuracy is a priority for you this upgraded barrel is a must!
