6,03mm S+ Precision Inner Barrel for AEG replicas
 A precision barrel made out of hardened stainless steel by the Taiwanese company T.N.T. Thanks to the innovative system of increasing the muzzle diameter and adding special grooves, the BB gains some additional accuracy and range T.N.T. Barrels are manufactured on very precise CNC machine, which ensures a high quality and accuracy of the barrel. 
 The S + version has a slightly different design of the barrel window, which affects the compression of the bucking by the spacer and thus further improves the accuracy. 
 The set includes, apart from the barrel itself, a high-quality, dedicated Hop-Up bucking.
