The Hera HRS fixed shaft is made of impact-modified polymer and is one of the most stable and lightest fixed shafts on the market. The removable covers can be used as additional storage or removed completely. The QD eyelets enable the mounting of sling swivel with a ball pressure system, which means that the stock can be used not only on the shooting range, but also for mobile use. The Hera HRS shaft has been specially developed for the AR15 / M4 platform and requires a typical A2 buffer tube. The HRS can also be used on all systems that have shaft dimensions in accordance with the AR15 system in the area of the buffer tube. Available in black, tan and green.
