Harri, Mark

Harri, Mark, doing business as Harri Contracting, is a California-based sole proprietor providing specialized firearms and explosives instruction services to the federal government as a prime contractor under total small business set-asides. All 124 recent federal awards are prime contracts issued as blanket purchase agreement calls by the Department of Justice Bureau of Alcohol, Tobacco, Firearms and Explosives, with no subcontract footprint and no engagement with other federal agencies.

Harri Contracting holds a narrow but deep customer concentration: the ATF accounts for 100% of awards and combined potential value ($1.4 million across 124 awards). The vendor operates exclusively under four multiple-award BPAs with the ATF established between 2013 and 2022, each with a $500,000 or smaller ceiling. The largest vehicle, Blanket Purchase Agreement DJA13AHDQS0229, has generated 46 task orders valued at $341 thousand; three other BPAs account for 74 additional task orders across $597 thousand in combined potential value. Individual BPA calls range from under $4,000 to $24,000, with most instructor and explosives specialist calls priced between $8,000 and $9,000 as short-term fixed-price engagements lasting one to four weeks. Work is performed primarily at Harri Contracting's facility in Blairsden-Graeagle, California, with occasional engagements at Redstone Arsenal in Alabama. Recent representative awards include an $8,000 instructor services call awarded May 31, 2026, with completion by June 12, 2026; an $8,086.77 instructor and explosives specialist call awarded March 22, 2026; and a $24,000 instructor services call awarded June 5, 2022.

Activity has remained flat to declining year over year—10 awards in 2022 dropping to 5 through mid-2026—indicating saturation within the existing ATF relationship rather than growth trajectory. Combined dollars obligated stand at $939 thousand against $1.4 million combined potential value, reflecting 65% realization across all awards in the source window. Harri Contracting's capability portfolio is narrow and specialized: instructor-led training in firearms handling, explosives investigation, arson investigation, and law enforcement skill development, delivered as short-cycle consulting support to ATF's workforce development and regulatory missions. The vendor competes entirely under total small business set-asides and holds no IDIQs, GWACs, or government-wide vehicles; all work flows through four single-customer BPA vehicles that expire or have already expired between 2025 and 2027, creating significant recompete exposure across the entire current award footprint.
