1147 results about "Gun barrel" patented technology

A gun barrel is a crucial part of gun-type ranged weapons such as small firearms, artillery pieces and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is introduced (via propellant combustion or mechanical compression) behind a projectile in order to propel it out of the front end (muzzle) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its caliber, usually measured in inches or millimetres.

Ambidextrous bolt release mechanism for firearm

A firearm with ambidextrous bolt release mechanism includes a barrel and a bolt slideably mounted in the receiver for axial movement between forward closed breech position in battery with the barrel and a rearward open breech position. A recoil spring biases the bolt forward. A side-mounted bolt catch lever is configured and operable to selectively hold the bolt in the open breech position, and disengage the bolt to reclose the breech when manually actuated. A transversely movable actuator plunger allows a user to release the bolt from the side of the firearm opposite the bolt catch lever side. The plunger comprises an inclined camming surface which slideably engages a mating inclined camming ramp on the lever. Wedging action applied to the bolt catch lever by the plunger rotates the lever about its pivot axis to disengage and release the bolt.
