AEG 6.01mm Precision Barrels of Action Army and Madbull. Free shipping on orders from € 99, -
The 6.01mm precision barrel is one of the narrowest inner barrels available and therefore gives the most precision to the bb.
It is somewhat important when you place such a barrel in your airsoft gun that high quality bb's are used. If you use cheaper bb's in this type of barrel it is possible that the bad finishing of the bb can cause it to get stuck in the barrel.
