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.

Apparatus and associated methods relate to a handgun brace arranged with a rigid structure extending radially away from a handgun trigger guard, and having a forward-facing surface configured to physically engage with at least one finger of a user's non-primary grip hand in a stable position below the handgun's barrel and in front of the handgun's trigger, such that a counter-force applied by the finger(s) at the forward-facing surface tends to prevent the handgun (especially the muzzle), from rising or rotating in response to shooting, such as due to muzzle jump. In an illustrative example, the brace may be releasably fixed to the handgun (e.g., as a modular handgun accessory). A handgun brace that substantially mitigates the unwanted effects of muzzle jump/recoil may advantageously yield higher shooting accuracy and beneficially promote proper handgun grip positioning.

A brace for stabilizing a handheld device such as a handgun against a user's forearm includes a vertically elongated body adapted to detachably engage a portion of the handheld device, and an arm pivotably connected to a portion of the body. The pivotable arm is selectably moveable between a stowed position wherein the arm is vertically aligned with the body, and a deployed position wherein the arm provides a surface against which a user's forearm is removably receivable to stabilize the handheld device when the body is engaged with the handheld device.

In some embodiments, a firearm mechanism comprises a bolt carrier comprising a bolt carrier cavity, a buffer comprising a buffer cavity and a weight arranged to travel between the bolt carrier cavity and the buffer cavity. The buffer cavity comprises a damping mechanism comprising a reduction in a cross-sectional size of the buffer cavity. In some embodiments, the damping mechanism and weight comprise a valve arrangement arranged to pressurize the buffer cavity and damp kinetic energy carried by the weight.

A firearm stabilization device is described that can be attached to a firearm to improve, increase, or maintain the stability of a firearm. The firearm stabilization device may include an electric motor configured to rotate a flywheel about an axis of rotation and a power source powering the electric motor. The electric motor, the flywheel, and the power source may be positioned within a housing. The fire arm stabilization device may include an engagement structure positioned on an outer surface of the housing for attaching (releasably or permanently) the firearm stabilization device to a firearm.

A handgun brace for stabilizing a handgun on a user's forearm includes a body adapted to detachably engage a support structure such as a receiver extension extending rearwardly out of the rear end of a handgun, a first arm extending generally downwardly from the body, and a second arm pivotally connected to the first arm. The second arm is selectively moveable between a stowed position wherein and end of the second arm is received against a side of the body, and a deployed position wherein the first arm and the second arm form a downwardly rigid forearm support structure under the body. The forearm support structure includes a continuous support surface upon which a user's forearm is removably receivable to stabilize the handgun when the body is engaged with the support structure of the handgun.
