Heckler & Koch Defense Upper Receiver Kits

The Arkansas Army National Guard seeks ten Heckler & Koch Defense upper receiver kits (Model No. 50253805) and ten handguard sets (Model No. 51000150) as critical spare parts for the H&K M110A1 Squad Designated Marksman Rifle system, with quotations due September 25, 2026 at 0800 Central Time. This is a total small business set-aside restricted to brand-name competition under 10 U.S.C. 3204(a)(1); only Heckler & Koch Defense authorized distributors, value-added resellers, and the OEM are eligible to quote.

Place of performance is Camp Joseph T. Robinson, North Little Rock, Arkansas 72199. Delivery must occur within 365 days after receipt of order under FOB Destination with freight prepaid. The estimated contract value is $40,000.00 on a firm-fixed-price basis with a 180-day delivery period after order. Funding comes from Operations & Maintenance appropriations under document identifier W912JF26QA012.

The government established sole-source justification under 10 U.S.C. 3204(a)(1) on grounds that Heckler & Koch Defense is the sole manufacturer of proprietary SDMR components. Technical factors precluding open competition include platform compatibility constraints with proprietary pin dimensions and bolt carrier group travel channels incompatible with standard mil-spec alternatives; gas system tolerances specific to the H&K upper receiver barrel interface that non-OEM components cannot replicate; handguard mounting geometry required to preserve the rifle's 1.5 MOA accuracy standard; and exclusive technical data rights held by H&K Defense. Market research conducted in September 2026 confirmed no alternative suppliers exist.

Equipment must be factory new OEM condition and meet End User Certificate compliance requirements. Award will be made to the responsible offeror offering best value based on technical confirmation that equipment is brand-name Heckler & Koch Defense and price fairness and reasonableness.
