About the company
M.N. Gumbert Corp, operating as S.O.T. Abrasives & Equipment, a Tulsa, Oklahoma–based small business limited liability company, supplies specialized industrial equipment and abrasive materials to defense and civilian federal agencies entirely as a prime contractor. The vendor competes primarily under total small business set-aside designations across purchase orders and delivery orders; approximately 77% of recent awards carry small business set-asides.
The vendor's concrete capability portfolio spans electrostatic and gravity-feed paint guns (Graco and DeVilbiss brands), paint spray booths, abrasive blasting systems, pump equipment (quad gun pump carts, paint pot units), abrasive materials (glass beads, sphericel beads), specialized surface-preparation equipment (abrasive floor auger systems), and protective expendables (respirator kits, breathing hoses, paint and chemical hoods). Representative prime work includes a $1.2 million total small business set-aside purchase order from Air Force Reserve Command for one paint spray booth (August 2025, Fort Worth), a $474.6 thousand total small business set-aside for electrostatic paint guns from Oklahoma City Air Logistics Complex (May 2024, Tinker AFB), a $553.4 thousand total small business set-aside for protective expendables from the same command (January 2024), and a $228.3 thousand total small business set-aside for sphericel beads from Joint Munitions Command (March 2025). The vendor also holds a single-award Indefinite Delivery Contract with the Army Aviation and Missile Command running through May 2030 for N-1S Almen Strips (surface-preparation materials), valued at $191.3 thousand.
Customer concentration sits heavily with defense sustainment commands. The top five customers by award count account for 77% of recent awards, dominated by the Oklahoma City Air Logistics Complex (21 awards, $2.8 million combined potential value) and the Air Force Sustainment Center (41 awards, $1.3 million combined potential value). Potential-value ranking elevates the Air Force Reserve Command (one $1.2 million paint booth award) above other customers; the two rankings thus diverge materially on dollars per award, with most sustainment-center work consisting of smaller-dollar equipment and consumables orders. The vendor has worked with 18 distinct federal agencies across recent awards, including the Army Corps of Engineers, Joint Munitions Command, Federal Aviation Administration, and General Services Administration.
The vendor places work under the GSA Multiple Award Schedule (nine task orders, $152 thousand combined potential value) and under the Army Aviation and Missile Command Indefinite Delivery Contract W912NW25D0003 (two task orders, $73 thousand combined potential value). Activity has grown modestly—one award each in 2021 and 2023, eight in 2024, six in 2025, and three so far in 2026—with three awards (combined potential value $347 thousand) reaching ultimate completion within the next twenty-four months. The vendor operates exclusively as a prime; no subcontract activity appears in the source. Combined potential value across 111 awards totals $7.9 million, with $7.6 million (97%) already obligated. Top NAICS codes are Abrasive Product Manufacturing and Industrial Machinery and Equipment Merchant Wholesalers (21 awards each), followed by Air and Gas Compressor Manufacturing (15 awards); top PSCs reflect the equipment mix—Power and Hand Pumps (17 awards), Aircraft Maintenance and Repair Shop Specialized Equipment (12 awards), and Abrasive Materials (11 awards).
