Harri, Mark

Harri, Mark, doing business as Harri Contracting, operates as a sole proprietorship providing specialized firearms, explosives, and law enforcement instructor services to the Bureau of Alcohol, Tobacco, Firearms and Explosives on a 100% small-business-set-aside basis as a prime contractor. The Loomis, California–based firm competes exclusively under total small business set-asides and holds no subcontractor positions; all 125 awards in the recent footprint are prime contracts or BPA calls.

Harri Contracting's customer base is singular and concentrated: all 125 awards totaling $1.4 million in combined potential value funnel through the Department of Justice's Bureau of Alcohol, Tobacco, Firearms and Explosives. The vendor provides short-term, fixed-price instructor-led training and explosives specialist consulting, delivered primarily at the company's facility in Blairsden-Graeagle, California, with occasional work at Redstone Arsenal in Alabama. Representative recent work includes BPA calls valued at $9,200 for instructor services (August 2026), $8,000 for instructor and explosives specialist services (May 2026, April 2026, January 2026), and $8,000 for explosives specialist consulting (February 2024, December 2023, October 2023). Individual call orders typically range from $3,700 to $24,000 and span one to four weeks in duration, with firm fixed-price structures.

The vendor's vehicle footprint is dominated by four multiple-award blanket purchase agreements, all with the ATF. The primary vehicle—Blanket Purchase Agreement DJA13AHDQS0229—has generated 46 task orders worth $341 thousand in combined potential value since the source data range began. Three additional BPAs account for 75 additional task orders: Blanket Purchase Agreement 15A00022AAQA00295 (28 task orders, $222 thousand), Blanket Purchase Agreement 15A00020AAQA00278 (26 task orders, $227 thousand), and Blanket Purchase Agreement 15A00018AAQA00369 (21 task orders, $157 thousand). The largest active IDV—a $500,000 multiple-award BPA effective through June 30, 2027—covers explosives specialist, instructor, and contract specialist services and has been the source of numerous call orders since its July 1, 2022 award date.

Activity has remained stable at nine to ten awards per year from 2022 through 2025, with six awards issued year-to-date in 2026. Combined obligated dollars stand at $940 thousand, representing 65% of the combined potential value across all 125 awards. The vendor registered in SAM.gov in June 2012 and has consistently delivered specialized, short-term training and explosives expertise to ATF since 2021. No subcontractors are identified across the portfolio, and the work is classified under NAICS 611719 (Educational Support Services) and 611430 (Professional and Management Development Training), with all awards coded to PSC Support–Professional: Other.
