Canon de précision 6,02mm en acier inoxydable GBB 98mm [ZCI]

ZCl makes amazing barrels for a low price.
That is all you need to know, really.

Mirror like finish inside, stainless steel, durable, no burrs or surface imperfections.
Nothing else in this price range compares to them.

I have several ZCl barrels, but they still impress me when I get a new one.
While other brands make brass or aluminium coated barrels in this price range, ZCl makes stainless steel barrels that will last a lifetime, there is no coating to get chipped or scratched that will ruin the whole barrel.
They are also much tougher and resilient, and they still provide a mirror like finish. No need to polish/buff the barrels, a quick clean and they are ready to use out of the box.

The latest barrel I bought is 98mm long, it is a perfect fit for the Army Armament R501. It greatly increased the accuracy of the guns, and slightly increased the FPS. I can really recommend the AimTop Titan Ultimate bucking to combine with this barrel (also available on TaiwanGun).
