Built Like A Tank To Withstand The Rigors Of Battle
Vltor Sight Tower (VST) is precision machined from solid tool steel to provide reliable function of the gas system and the option for emergency back-up sight deployment during battle conditions. Dual clamping rings fit a standard .750" diameter barrel and can withstand up to 100 ft-lbs of rotational torque without failure. Hex head clamping screws can be staked after installation for added security. Short Picatinny rail on top of the gas block is the same height as a standard M4 flattop rail and allows mounting of small tactical accessories when sight is folded. To avoid damage, the front sight tower is non-locking and uses spring-loaded plungers and detents for automatic disengagement if struck during combat. AK-style, front sight post is easy-to-adjust with the included sight tool. VST-2C has the same great features as the VST-1C but without QD sling socket.
