Abstract: An adjustment tool assembly for a firearm comprised of a double-sided adjuster tool and a housing having a handle. Each end of the double-sided adjuster tool can be comprised of a tool, each tool can have a shaft, and a middle portion can be positioned between the shaft of each tool end. The handle of the housing can have a receiving cavity for at least a portion of the double-sided adjuster tool, and the middle portion of the adjuster tool can engage with the receiving cavity to secure the adjuster tool to the handle.

Abstract: A bore guide comprised of a rear housing, an adjustable shaft having a proximal and a distal end, a tip on the distal end of the adjustable shaft, a spring housing connected to the proximal end of the adjustable shaft, a spring located inside the spring housing, and a lock insertable into a portion of a firearm to lock the spring in a compressed state. The rear housing may have a rear opening on a proximal end of the rear housing and a solvent port on a circumferential portion of the rear housing. Transition of the adjustable shaft toward the rear opening can cause compression of the spring. The lock can secure the bore guide in place and create a seal within the bore of the firearm.

Abstract: An adjustable support stand can include a front support on a first end of the adjustable support stand having a grip comprised of a first, front support material; and a rear support on an opposing, second end of the adjustable support stand having a grip comprised of a first, rear support material, wherein the front and the rear supports can each have at least two vertical arms, at least one of the supports can have vertically stacked chevron voids on each arm, and the chevron voids can be deformable by the object being worked upon to secure and grip the object in place.

Abstract: Exemplary embodiments of the present invention relate methods and devices for measuring flow rate of particulate matter within an exhaust gas stream. In one particular exemplary embodiment, a sensor for detecting and monitoring particulate matter within an exhaust flow path of an engine is provided. The sensor includes a housing having an attachment for mounting the sensor. The sensor also includes a sensing rod supported by an insulating base. The sensing rod is attached to the housing and includes a probe adapted to be placed within the exhaust flow path. The probe includes a section having an increased surface area per unit length as compared to at least one other section of the probe. The sensing rod is configured to detect particulate matter flowing through the exhaust component and generates a signal based thereupon. The sensor further includes an electrical connector in communication with the sensing rod.
