U.S. Army Orders More MK22 multi-caliber Kits
The U.S. Army has approved a $14.2 million modification to a Barrett Firearms Manufacturing contract for additional MK22 barrel kits.
According to the contract notice, Barrett Firearms Manufacturing Inc., Christiana, Tennessee, received modification P00009 to contract W15QKN-21-D-0028 for $14.2 million. The action raises the contract’s total cumulative face value to $64.1 million. Bids were solicited via the internet, with one received, the announcement said.
Work locations and funding will be set with each order, and the contract carries an estimated completion date of March 30, 2026. The Army Contracting Command, New Jersey, is the contracting activity.
The MK22 is intended as a modular precision system that gives shooters the option to tailor their loadout to mission needs. The MK22 is more than just another rifle; it results from a partnership across the Department of War. The system supports caliber conversion, with barrels chambered in 7.62mm, .300 Norma Magnum and .338 Norma Magnum. That flexibility allows units to change barrel assemblies and adapt the weapon for different engagement ranges and mission profiles.
Each delivered kit includes three barrels, a hard and soft carrying case, a comprehensive cleaning and tool kit, a sound suppressor, the M317 PDO and its accompanying scope mount. Those components reflect a design approach that seeks to give small units organic sustainment and modularity in the field.
Unlike older sniper rifles that required evacuation to an intermediate repair level, maintenance on the MK22 can be performed at the organizational level. If a barrel fails, the rifle can be reconfigured in another caliber and returned to service quickly, a feature the services view as a way to reduce downtime and keep shooters ready.
The contract modification covers both 7.62-caliber and .338-barrel kits, consistent with the service’s move to field systems that span medium to extended-range engagement. The procurement is part of a broader effort to standardize and modernize precision small arms across the force, blending a proven bolt-action and semi-automatic heritage with modular engineering to meet evolving mission demands.
Procurement officials have in recent years sought systems that reduce logistics strain and increase mission flexibility. The MK22’s kit approach — multiple barrels, integrated suppressor and a full complement of mounts and tools — is explicitly aimed at giving unit commanders options without requiring a separate family of weapons for each role.
With an estimated completion in March 2026, the program will deliver kits over the next year and a half, with work sites and funding determined per order. The contractual language positions the MK22 as an effort to improve sustainment and field adaptability while preserving operational reach through multi-caliber capability.
