Small arms stabilization system
A self-stabilizing small arm having a barrel assembly rigidly connected to a stock assembly. The small arm includes at least one shooter interface surface and a stabilization assembly controlling the relative position of the shooter interface surface and the barrel assembly or stock assembly. The stabilization assembly includes (i) at least one movement sensor; (ii) at least one actuator; and (iii) a controller using signals from the movement sensor to operate the actuator in order to compensate for unintended movement of the small arm.

6. A self-stabilizing small arm comprising:
a. a barrel assembly rigidly connected to a stock assembly;
b. a stock plate positioned on the stock assembly;
c. a stabilization assembly controlling the relative position of the stock plate and stock assembly, the stabilization assembly including:
i. at least one movement sensor;
ii. at least one vertical actuator;
iii. at least one horizontal actuator; and
iii. a controller using signals from the movement sensor to operate the actuators in order to compensate for unintended movement of the small arm; and
