Abstract

The present invention relates to an active system configured to apply an active force to a portion of a firearm designed to contact a body of the firearm's operator, to reduce the perceived recoil of the firearm. The active system includes an actuation element capable of generating an active force, and systems for powering and selectively operating the actuation element.

Abstract

The present invention relates to increasing the flight stability of a bullet in subsonic flight. The bullet may incorporate features that impart additional angular momentum during flight. Helical fins may be configured such that laminar airflow over the bullet during flight increases rotational forces, thus increasing the angular momentum of the bullet and stabilizing it during flight. The fins may be self-forming during the use of the bullet or may be formed during manufacturing.
