VKTR V31100916604CA 5.56 NATO 13.7 SOLNOX suppressor Carbine

The VKTR V31100916604CA FRGD 556 13.7 SOLNOX is a purpose-built modern rifle platform engineered for operators and enthusiasts who demand suppressor compatibility without performance compromise. This 5.56 NATO carbine integrates a patented low-profile piston gas system designed to cycle reliably both suppressed and unsuppressed across varying ammunition types, eliminating the need for manual gas block adjustments between configurations.

The VKTR rifle features a staged gas bleed system that optimizes gas port sizing and flow—a critical advantage for suppressed shooting where excess back-pressure can cause short-stroking or over-gassing. The system employs a proprietary cup and spigot piston design that improves the gas seal and overall efficiency of the gas operation, paired with a fully-supported one-piece operating rod assembly that reduces wear and extends component life. At 13.2 pounds and 42.4 inches overall, the FRGD 556 13.7 configuration offers a practical balance of maneuverability and sight radius for both tactical and training applications.

This platform serves law enforcement, military personnel, and civilian shooters who prioritize reliability in variable conditions. The suppressor-ready design is particularly valuable for operators conducting training at indoor ranges or in noise-sensitive environments where shot-count and ammunition variety demand a gas system that adapts to both factory and specialty ammunition. The removable operating rod simplifies field maintenance and cleaning—critical for platforms experiencing higher round counts or extended deployment cycles.

VKTR Industries positions the VK-1 as a direct-impingement alternative with piston reliability. The modern piston design avoids the gas tube corrosion common in suppressed AR-platform rifles while maintaining the ergonomic and modularity standards shooters expect. The armored black finish provides corrosion resistance suitable for both stateside training and field deployment in humid or salt-air environments.
