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-1 series incorporates a QD sling swivel cup mount. All models use an AK47/AKM/AK74 front sight post. This allows the user adjust the sight, for elevation, with the use of a simple AK cleaning kit.
Despite the VST's solid construction, it actually weighs less than a standard A2 front sight tower. The VST-1P comes with QD-sling swivel mount and a taper-pin mounting (gunsmith installed).
Installation note: The installation of the VST should only be performed by a qualified gunsmith and/or certified armorer.
The clamping system has been carefully designed to provide an unparalleled hold when installed properly. During testing, the VST-1 withstood over 100 ft/lbs of rotational torque and is stronger than the barrel’s receiver indexing pin.
