GBB inner Barrels

Greater precision and range – Inner Barrels for GBB replicas

Want to transform your GBB pistol or gas rifle into a precision weapon? Then high-quality inner barrels are one of the most effective upgrades. Not only do they run tighter and smoother than stock barrels, but they also reduce friction and ensure a more consistent BB trajectory. Perfect for those who take their airsoft replica seriously – whether for CQB or outdoor use.

Why choose a GBB inner barrel upgrade?

Standard barrels in GBB replicas are often good, but not optimised. By switching to a precision inner barrel with a smaller diameter and better finish, you can take your performance to the next level. In combination with a good bucking, you will immediately notice a difference in accuracy, group size and effective range.

What can you find in this category?

• Inner barrels in diameters from 6.01 to 6.05 mm
• CNC-milled precision tubes for minimal tolerances

• Airsofters who want maximum precision from their GBB

Precision starts at the core – choose an inner barrel upgrade for your GBB.
