The VST folding front sight and gas block is an all-steel, flip-up design, with spring loaded detents. There is no lock so if the sight gets hit, the sight will fold down rather than damage a locking mechanism. The VST incorporates a QD sling swivel cup mount. The VST use a AK47/AKM/AK74 front sight post. This allows the user to adjust the sight, for elevation, with the use of a simple AK cleaning kit.
