The Tech-15 Stryker runs a dedicated rimfire blowback bolt, purpose-built for .22 LR in the AR-15 platform. This setup delivers straightforward operation with the advantages of a lightweight, low-recoil rimfire system made in the USA.
Fostech’s Echo Sport binary trigger is installed from the factory. It provides pull-and-release operation with an in-guard mode paddle, giving the user clear, intuitive control over trigger mode selection.
The 17 inch barrel is a medium profile and threaded, with a ported muzzle device installed. This configuration supports easy attachment of compatible muzzle accessories while maintaining balanced handling.
The Mach-2 free-float M-LOK handguard is constructed from magnesium-aluminum alloy, combining rigidity with low weight. It carries Fostech branding with a USA insert, and works with the flat-top Picatinny receiver rail, forward assist, and dust cover for a clean, modern upper configuration.
Furniture includes a collapsible polymer stock with an adjustable length of pull of approximately 10–13.5 inches and a Fostech polymer pistol grip. The rifle is finished in matte black and marked TECH 15 MULTI on the lower. Capacity is 30+1 with the included 30-round magazine.
