A device comprised of bubble level inserted into and secured within a cavity located above the rifle grip and behind the barrel to facilitate the measurement and compensation of the rifle's cant while lining up the rifle's sights. The device is precision machined to allow the bubble to be aligned with the axis of the barrel to produce a true “zero-cant” condition. Graduation markings are placed on either left or right of the bubble level to allow the user to better judge the relative degree of cant. A light source is placed adjacent to the bubble level to illuminate cant for a shooter in a dark environment. Methods of using the embedded cant indicator for precision shooting are presented.

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.

The present disclosure incorporates a spinning rotor/mass, a single or multiple gimballed points on one gimballed axis and to the focus the power of precession to “physically” provide resistance against the movements of the device it is attached to. That is why this device is called a Gimballed Precession Stabilization System. A Gimballed Precession Motor(s) of the present disclosure can be placed in a single or in multiple positions on a Firearm to achieve resistance to an angular change. A Gimballed Precession Motor(s) may be used in one or more positions depending on the desired angular constraint. The motor can be self-contained and can be designed to rotate at a high speed and allow the pivoting of the device on its mounting Gimbal Pivot Axis.

A firearm assembly, capable of firing bullets, includes a firearm assembly kit and a firing control unit (“FCU”). The FCU, in one embodiment, is disassembled from a handgun which is operable by one hand and capable of initiating firing a bullet when a trigger of the FCU is pulled. The firearm assembly kit is configured to house the FCU to form an operable firearm resembling a semiautomatic rifle operable by two hands. The kit includes a grip module and an extended firing slide (“EFS”). The grip module includes a handgrip, an FCU housing, a trigger guard, and a magazine port, wherein the trigger guard is situated between the handgrip and the magazine port which is located in front of the handgrip away from the user. The EFS facilitates firing of bullets from a magazine inserted in the magazine port via an extended firing pin.
