  • 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!
