Hop Up group complete with Hop Up rubber and Precision barrel 6.03mm x 275mm TNT for Hk416-A5 GBB VFC series

Hop-Up chamber complete with barrel 6,03 mm 275 mm for VFC HK416A5 replicas

A set consisting of a complete aluminum Hop-Up chamber and a precision barrel 6,03 mm nickel-plated inside and bronze outside.

Thanks to the implementation of an innovative system in the form of an increased barrel exhaust diameter and the addition of special grooves, a bottom bracket has greater precision and reach. Therefore, the barrel has two diameters: inlet diameter of 6,03 mm and discharge diameter of 6,35 mm. T.N.T rods are produced using very precise CNC machines which guarantee high quality and precision of the rod.

The set includes, in addition to the barrel and chamber, a dedicated hop-up with a hardness of 60O.

The implementation of a high-quality barrel and Hop-Up overhang improves the accuracy and range of a replica.

A drop-in set intended for installation in VFC's GBB HK416A5 replicas.
