U.S. Special Operations Command just announced the DoD had formally chosen a modified SIG MCX upper to fill the request of the Suppressed Upper Receiver Group or SURG program.
SIG wasn’t the only company to submit a design for the SURG RFP, however. At least two other companies delivered specialized, functional SURG designs that were inched out by SIG’s modified, piston-driven MCX upper.
The first was from long-time sound suppressor manufacturer, GemTech. Founded in the 1970s, GemTech has been producing military and civilian suppressors for decades. With their massive breath of experience, the engineers at GemTech submitted their Integra Upper to the SURG RFP.
As its name suggests, the Integra features a sound suppressor integrated into the barrel itself. In fact, only the first 10.5 inches of the barrel are rifled, and the remaining 5.5 inches are simply a sound suppressor — though this is mostly in line with the SURG requirements set forth by SOCOM (GemTech’s submission actually offers 1.7 additional inches of rifled barrel)
