G17 Gen4, G19 (T.Marui) CNC Steel Enhanced Knocker

This high tensile steel knocker is made by precision CNC machines. It fits G17 Gen4, G19 (T.Marui) GBB pistol. It is an enhancement item, which is specially made for professional shooter and competition needs, because:

1) Highly precise dimension increases shooting reliability and sensitivities;

2) High tensile steel construction, increases durability and reliability;

3) Smooth surface finishing reduces friction inside the chassis and improve smoothness of knocking movement;

4) Dimension is modified for increasing efficiency and reducing risk of misfire. Therefore, it has difference dimension from the original T.Marui knocker.
