Zistos Corporation

Zistos Corporation, doing business as Zistos Corp, manufactures specialized video borescope inspection equipment, cannon bore gauge sets, and precision measurement tools for defense and federal law enforcement agencies as a prime contractor exclusively. The Holbrook, New York–based for-profit Subchapter S corporation competes on full-and-open procurements with no SBA set-aside designations, though it holds a $13.8 million single-award indefinite delivery contract with Defense Logistics Agency Land and Maritime designated as a total small business set-aside, awarded in September 2020 and running through September 2025.

Zistos sells optical inspection systems, video borescopes for gun bore and equipment inspection, precision cannon bore gauge sets, disk master gages, cable assemblies, display units, and supporting components—equipment critical to military maintenance, repair, and overhaul operations. The company has supplied these products across nearly two decades of federal contracting; representative recent work includes a $525.8 million delivery order from DLA Land and Maritime in November 2023 for video borescope equipment, a $235.5 million purchase order from DLA Troop Support Construction and Equipment in April 2024 for 16 cannon bore gauge sets, a $249.6 million sole-source purchase order from the Department of the Air Force (awarded February 2022) for a gun bore inspection system, and a $27.5 thousand purchase order from the Coast Guard in December 2022 for borescope upgrades at Curtis Bay, Maryland.

Customer concentration sits overwhelmingly with the Defense Logistics Agency. DLA accounts for roughly 88% of recent awards: DLA Land and Maritime leads with 55 awards valued at $23.7 million combined potential value, and DLA Troop Support Construction and Equipment accounts for 86 awards totaling $5.7 million. Together these two DLA divisions represent 89% of all awards. Secondary customers include the Department of Homeland Security US Coast Guard (5 awards, $201 thousand), Naval Sea Systems Command (5 awards, $392 thousand), and the Department of the Army Picatinny Arsenal (2 awards, $550 thousand). The top-by-count and top-by-value rankings align closely—DLA Land and Maritime dominates both dimensions—indicating deep operational integration rather than transactional relationships.

The company places work through a single identifiable parent vehicle: an indefinite delivery contract (SPE7LX20D0208) from which 24 task orders have been issued carrying $5.5 million in combined potential value. Most remaining work flows as individual purchase orders and delivery orders under various DLA divisions' standalone procurement authorities rather than through government-wide vehicles or multi-award IDIQs.

Zistos operates almost exclusively as a prime contractor—100% of the source awards are prime awards with zero sub-award footprint reported. The company is not identified as a subcontractor to other federal primes in the available award data, though one summary reference mentions prior work as a subcontractor to Leidos and Atlantic Diving Supply on undisclosed contracts.

Award activity has grown substantially: 15 awards in 2022, 19 in 2023, and a peak of 35 in 2024, declining to 14 in 2025 and 3 in 2026 year-to-date. Combined potential value across the entire footprint sits at $31.3 million with $16.9 million obligated (54% burn). The source does not specify a recompete cliff; the 2025 DLA Land and Maritime indefinite delivery contract runs through September 2025, meaning renewal or recompete opportunity surfaces in the next few months.

Primary NAICS concentration aligns with manufacturing: Cutting Tool and Machine Tool Accessory Manufacturing (70 awards), Optical Instrument and Lens Manufacturing (36 awards), and Commercial and Service Industry Machinery Manufacturing (14 awards). Top PSC codes are Sets, Kits, and Outfits of Measuring Tools (55 awards) and Optical Instruments, Test Equipment, Components and Accessories (47 awards), confirming the hardware-centric, precision-inspection posture across the entire footprint.
