The disclosure provides a mounting assembly for a handguard mounted on a barrel nut of a firearm. The handguard defines a gap over a portion of the barrel nut and includes first and second portions at respective first and second sides of the gap. The mounting assembly includes a tie rod extending between the first and second sides of the gap along a longitudinal axis of the tie rod and a first fastener, distinct from the tie rod, interconnecting a first end of the tie rod to the first portion of the handguard. A second end of the tie rod is interconnected to the second portion of the handguard and actuation of the first fastener in a tightening direction draws the first and second portions of the handguard toward each other and generates tension in the tie rod.

A charging handle, charging handle latch, and firearm with a charging handle. The charging handle includes a charging handle body that extends between a front and a rear of the charging handle; a crossbar at the rear of the charging handle, wherein the charging handle body has a top surface and a bottom surface opposite the top surface, wherein at least a portion of the bottom surface bottom surface defines a first plane. The charging handle further includes a latch pivotally connected to the charging handle, wherein the latch includes a gripping surface configured to be depressed by a user, wherein an extension portion of the latch extends below the first plane.

A rifle with an auto-loading mechanism having a gas chamber with a guiding tube connected to a gas adapter, and a piston assembly including an impact damper, a piston slidingly movable within the gas chamber, a guide fixed to the piston at one end and provided at its other end with a blind hole, a fixed piston slidingly movable at one end within the blind hole of the guide and fixed to the impact damper at the other end, a helical spring arranged within the blind hole of the guide and a return helical spring arranged around the guide in a way to lean against a stop in the guiding sleeve with one end and against the impact damper with the other end, wherein the gas chamber is arranged on the rifle barrel in the area of the barrel receiver. The advantage of the rifle lies in that it allows for more accurate shooting, has lower weight and less recoils.

An action for a firearm uses a rotating barrel on which are mounted lugs and a cam follower. The barrel is positioned coaxially within a tube fixed to the frame of the firearm. A cam, engaged by the cam follower, is also fixed to the frame. A gas space is defined between the tube and the barrel by a thrust surface on the barrel and a reaction surface on the tube. A gas port connects the gas space with the barrel's bore. A slide overlies the tube and defines longitudinally oriented grooves which receive the lugs when the barrel is rotated by interaction between the cam and the cam follower to align the lugs and the grooves. Motion of the barrel is arrested by interaction between the cam and cam follower, and motion of the slide relative to the barrel is permitted when the lugs align and engage the grooves.

An assembly for directing propellant gas to an action of a firearm includes a barrel and a gas block. The barrel has a plurality of gas ports that communicate with the bore of the barrel. The barrel and the gas block define a passage that receives pressurized propellant gas from the bore by way of the barrel gas ports, and directs the propellant gas to a gas port of the gas block. The plurality of barrel gas ports and the passage act as a manifold in which the propellant gas is taken from multiple locations within the barrel, combined into a single flow, and directed into the gas block via the gas block gas port. The pressurized gas is then routed to an action of the firearm by way of a gas tube and a gas key.
