Semiflex collar bolt for Vz.58 stocks

The strength bolt for attaching the G3, Aggressor and Tactical Spirit stocks and other Detonics adapters, as well as the original Sa58 folding stock, is a more perfect variant and a replacement for the inconvenient original bolt.
 

Advantages of the G3 screw:

Compared to the original screw with a screwdriver notch, the G3 screw is equipped with an Allen head (hexagonal internal profile No. 8), which allows a safer and more firm tightening of the stock to the weapon without the risk of tearing off the tightening edges.

The bolt has a partially flexible collar head, which after tightening permanently pushes the stock to the body of the weapon. This significantly reduces the risk of stock release.
