The Department of Defense has announced that USOCOM selected SIG SAUER to provide SURG.
Sig Sauer Inc., Newington, New Hampshire, was awarded a $48,000,000 five-year, indefinite-delivery/indefinite-quantity, firm-fixed-price contract for the acquisition of the Suppressed Upper Receiver Group (SURG). The SURG weapon is an upgrade of the M4A1 lower receiver group in support of U.S. Special Operations Command (USSOCOM) Procurement Division. Fiscal 2018 procurement funds in the amount of $24,620 are being obligated at the time of award. The majority of the work will be performed in Newington, New Hampshire, and is expected to be completed by July 2023. This contract was awarded through full and open competition. USSOCOM headquarters, MacDill Air Force Base, Florida, is the contracting activity (H92430-18-D-0005).
SURG is a 5.56mm, integrally suppressed upper receiver. Despite assertions to the contrary on other websites, this is not a SIG Rattler kit.
However, there an entirely different program to offer a Personal Defense Weapon upper in .300. Earlier this year, SOCOM purchased a handful of SIG upper receiver systems to inform the requirement. Expect SOCOM to release a solicitation in FY19.
SURG asked industry to keep the handguard cool enough to handle even after firing the SOCOM suppressor torture test with M855A1. Several companies took up the challenge but experienced various issues.
