Knights Armament Company (KAC) Rifle Replacement Parts and Accessories

The U.S. Secret Service (USSS) intends to award a sole source Indefinite Delivery, Indefinite Quantity (IDIQ) Contract to Knights Armament Company (KAC) for rifle replacement parts and accessories. This contract is for KAC original equipment manufacturer (OEM) replacement parts for their SR-16 and SR-25 rifle families, as well as associated KAC suppressors. The USSS currently uses KAC platforms and accessories and requires genuine KAC OEM parts to maintain performance, reliability, and safety due to the specialized law enforcement purpose of these weapon systems. Non-KAC parts are not technically acceptable. The North American Industrial Classification System (NAICS) code for this effort is 332994. No known alternate sources exist that could satisfy the USSS's requirement. Interested parties who believe they can meet the requirement must submit written evidence of their capability by 4:00 PM EST on May 22, 2026, to Theresa.Williams@usss.dhs.gov and Erik.Syfert@usss.dhs.gov.
