PEO-Soldier Grenadier Sighting System (GSS)

The U.S. Army Contracting Command – Picatinny Arsenal awarded a Master IDIQ on March 29, 2016, for development and production of the Grenadier Sighting System (GSS), a targeting module for the M320/M320a1 grenade launcher. The ordering period closed on March 28, 2022; no new task orders may be placed against the vehicle.

Although the vehicle is formally expired, task-order activity has continued post-close-out. Nineteen delivery orders have been awarded with a combined potential value of $390.8 million, of which $89.2 million (23 percent) has been obligated. The most recent order was issued on June 11, 2025. Ordering momentum has stabilized at roughly two orders per year since 2023, following higher activity in 2021–2022.

The work is overwhelmingly production-oriented: task orders procure GSS units in quantity, along with software-update kits, cables, battery caps, and first-article testing. Early prototype orders (2016–2018) used Cost Plus Fixed Fee pricing; all subsequent production orders are Firm Fixed Price. The vehicle began as a competitive development award and transitioned to production, with engineering-change proposals (ECPs) driving quantity and price updates across multiple orders.

Wilcox Industries Corp. dominates the award history, holding 16 of 19 orders worth $236.6 million combined potential value. American Rheinmetall Systems LLC holds the remaining three orders, valued at $154.2 million combined potential value. This two-contractor split reflects the original design-competition structure carried forward into production phases.

Customer concentration is extreme: Program Manager Soldier Weapons placed 15 of 19 orders representing $390.3 million of the combined potential value. Four other agencies (Navy, Army Materiel Command at Picatinny, Army Ammunition PM, and Air Force DFAS) placed single token orders totaling roughly $540 thousand.

Eighty-nine percent of task orders carry no set-aside designation; two small-business orders represent 11 percent of the award count but negligible dollar value. All orders use Firm Fixed Price or Cost Plus Fixed Fee pricing. Task-order values range from $15 thousand (small accessory orders) to $31.5 million (production units with first-article test). Recent obligated amounts cluster between $12 million and $15 million for full-production runs. Place of performance is military infrastructure (Picatinny Arsenal administrative oversight) with component manufacturing and assembly by the two primes.

The U.S. Army Contracting Command - New Jersey, Picatinny Arsenal, NJ, in support of the Program Manager Soldier Weapons, has awarded a Master IDIQ for the development and production of the Grenadier Sighting System (GSS). Under this program, the contractor shall develop, manufacture and produce the GSS which will effectively engage targets with the M320/M320a1 grenade launcher module.
