Product Overview
KFF Defense presents Remington Subsonic Rimfire ammunition, purpose-built for applications demanding minimal sound signature and consistent terminal performance. This 22LR offering is the result of a collaborative development effort between Remington and Advanced Armament Corporation (AAC) experts, integrating design elements optimized for suppressed firearm platforms.
Performance Characteristics
This ammunition is engineered to operate reliably below the speed of sound, mitigating the supersonic crack often associated with standard velocity rimfire loads. Precision manufacturing ensures tight velocity control across production batches, contributing to consistent point of impact and reduced sonic disturbance. The subsonic velocity profile makes it ideal for suppressed training, hunting, and operational use where discretion is paramount.
Bullet Design
The 40-grain projectile features a copper-plated hollow point design. This plating minimizes lead fouling within a suppressor’s baffles and bore, enhancing system longevity and reducing maintenance cycles. The hollow point cavity is optimized for reliable expansion and energy transfer at the inherent lower velocities of subsonic ammunition, ensuring effective terminal performance on appropriate targets.
