Gemtech Integra 5.56 integrally silenced AR15 upper
Gemtech competed in the SURG program to develop a highly effective suppressed AR15 upper. The SURG program ended but Gemtech brought the system they were working on to the commercial market as the INTEGRA line of integrally suppressed AR15 uppers. We take a look at the 5.56mm variant of the Gemtech INTEGRA.
