This disclosure describes a firearm stock or arm brace with an adjustable length of pull. The stock or arm brace can include a body and lower stock, where the body includes a buffer tube receiving aperture and the lower stock includes a hollow cavity with a plunger and two concentric springs therein. One or more buttons can be affixed to sides of the plunger in the hollow cavity that can be used to depress the plunger against the force of one or both of the springs. One of the two springs may be shorter than the other and have a greater spring constant than the longer spring. Depressing the plunger against the taller spring may allow a user to adjust the length of pull while greater pressure and engagement of the second spring allows the stock or arm brace to be removed from a buffer tube or receiver extension.

An apparatus for stabilizing firearms is disclosed. The apparatus comprises a body having a left side module and a right side module secured together by a combination of locking mechanisms. An extendable rail with a support brace provided at the rear end is connected to the body of the apparatus. Further, a back securement disposed at the bottom side of the body, wherein the back securement is connected to the left side module of the body using a first side securement and the right side module of the body using a second side securement. Furthermore, a key for locking the extendable rail in a plurality of configurations is provided. Herein, the key is inserted through one or more keyholes provided in the extendable rail and a socket provided at the rear end of the body.

Disclosed is a butt stock that is reversibly attachable to a handgun, the butt stock having a compact state and a deployed state. The butt stock is relatively compact when in the compact state, but when attached to a handgun in a deployed state may provide multiple points of contact that potentially increase the accuracy of the handgun.

A brace apparatus for use with a firearm provides a mounting housing and a brace which is automatically deployable from a first position where the brace is in closer proximity to the mounting housing to a second position where the brace is distanced from the mounting housing, the brace being positioned for resting against a part of the user's body during firing of the firearm.

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.
