A gun sight assembly includes a housing with an inner bore and a sleeve. The sleeve has an axial cavity in which a luminescent source may be housed. The sleeve is press-fit into the bore such that complementary engagement features of the bore and the sleeve engage each other to lock the sleeve in place within the bore. In one version, the sleeve can be first received within an adapter configured for press-fit into the bore of the gun sight blank.

A gun sight system including a front sight portion and a rear sight portion. The rear sight portion comprises a circular cylinder sided and formed by incomplete triangles pointing to circular cylinder from each side. In some embodiments, the front sight portion comprises a non-hollow circular cylinder. When the front sight circle is aligned horizontally and vertically to the center of the rear sight, an image of two circles is formed for the user and a target is placed in the center of the point of the circle of the front sight.

A pistol has a frame having a grip, an elongated slide connected to the frame and operable to reciprocate on the frame between a forward battery position and a rear position, the elongated slide having opposed forward and rear ends, a rear sight connected proximate the rear end of the elongated slide, the frame including a front sight support element at a forward frame end forward of the forward end of the elongated slide when the elongated slide is in the forward battery position, and the front sight support element including a front sight operably registered with the rear sight when the elongated slide is in the forward battery position. The elongated slide may define a passage receiving a barrel defining a muzzle aperture, and wherein the front sight support element defines an opening registered with the muzzle aperture.

A firearm front sight post that is comprised of a camera assembly which captures an image or video, or a series of images or videos of what is in front of the firearm at the instant that the firearm is first fired, and at the instant that each and every subsequent shot is fired. The camera assembly is actuated by an actuation mechanism in communication with the trigger assembly of the firearm, and is activated when the trigger wall is met in the act of pulling the trigger of a firearm. The system is also comprised of a wireless transmitter that automatically sends the image/video from the camera assembly to a mobile application on a smartphone or other smart device, wherein the images/videos are encrypted, time-stamped and dated.

A firearm including a barrel, receiver, indirect gas system and an adjustable gas block designed to interface with the indirect gas system is provided. Four indexable positions of adjustment are provided for on the adjustable gas block. Positions of adjustment are selected based on the use of a silencer, use of under-powered ammunition, the presence of un-burnt powder and debris in the host firearms operating system, or if the weapon is being fired under “ideal” circumstances. The provided gas block is designed to function with an indirect gas operating system. Excess gas from the operating system is not vented from the gas block thereby generating excess flash and sound. No tool is required to manipulate the adjustment mechanism of the gas.

An assembly comprising a firearm slide and an adaptor plate configured to mate with the firearm slide. The adapter plate includes a first seat in a top surface of the adaptor plate and a second seat in the top surface of the adaptor plate. The assembly also includes a first iron sight configured to mate with the first seat and a second iron sight configured to mate with the second seat.
