  • Patent number: 10605558
    Abstract: A suppressor for a firearm includes a casing that defines a rear end opposed to a front end. A plurality of baffles are inside the casing. A rear cap is upstream from the plurality of baffles and releasably coupled to the rear end of the casing, and the rear cap includes an upstream surface. A rear cap surface feature is defined by the upstream surface of the rear cap. A front cap is downstream from the plurality of baffles and releasably coupled to the front end of the casing, and the front cap includes an upstream surface. A front cap surface feature is defined by the front cap, and the front cap surface feature has a complementary shape to the rear cap surface feature so the front cap surface feature can engage with the rear cap surface feature to remove the rear cap from the casing.

  • Patent number: 10605550
    Abstract: A quick release pin is used in a firearm to secure a barrel assembly to a frame and a recoil assembly within a slide. The cylindrical body of the pin functions similarly to traditional takedown pins and pivot pins used with firearms while the lever arm has unique features that are an improvement over traditional takedown pins. The arm has a locking lip at its proximate end, a detent at its distal end, and a cut-out center section which is thinner than the distal end and proximal end. The cut-out center section creates a space between the arm and the firearm's side when the arm is in its locked configuration which provides side edges for a user to grasp the edges of the arm between a finger and thumb while the thicker distal end of the arm is in flush contact with the side of the firearm.

  • Patent number: 10591247
    Abstract: A handguard attachment assembly for a firearm is disclosed. The assembly includes a handguard with an elongate structure extending between a first end and a second end, where the handguard has at least one opening proximate the first end. A flange insert is received in an opening on a first side of the handguard and engages the handguard. A fastener secures the flange insert to a connector positioned over the barrel nut. The fastener can be tightened to draw the handguard to the barrel nut. The connector can be a bridge connector positioned on or over the barrel nut within the handguard, or can be a connector with a flange portion that engages the second side of the handguard and has a connector body that extends towards the flange insert on the first side, to name a few examples.

  • Patent number: 10591239
    Abstract: A modular precision rifle assembly 150 and a method for configuring rifle components allowing users to change barrel subassemblies 214 (i.e., for a replacement barrel for use with the same ammunition or a barrel configured for shooting a different ammunition caliber or type) includes three main components including a receiver subassembly 212, a barrel subassembly 214 and a forend subassembly 200. The receiver subassembly 212 includes a receiver housing 300 with a central lumen defining a plurality of substantially cylindrical contiguous cavities aligned along a central axis 300CA. The barrel assembly's bore is automatically forced into axial alignment with central axis 300CA when a user tightens a barrel coupler nut 500 against a barrel extension 400 due to the centering force generated when the extension's centering surface 410 bears against the coupler nut's cooperating centering surface 520.

  • Patent number: 10578385
    Abstract: A trigger mechanism for a firearm is presented. The trigger mechanism has a trigger housing, a sear, a sear block and a trigger lever. Actuation of the trigger causes the trigger lever to rotate and eventually come into contact and move the sear block, which permits the sear to fall and permits the actuation of the firing mechanism. The trigger lever may be pivotally secured to the housing at a first pivot and the sear block is pivotally secured to the housing at a second pivot. The first and second pivots may be spaced apart from each other or coincident.

  • Patent number: 10533819
    Abstract: A conduit (5) with a bullet passage (13, 17) extends forward from a gun muzzle (7). Inner and outer concentric chambers (25, 29) surround the conduit and a forward portion of the barrel (3). A gas path (P2, P3, P4) is provided through sides of the conduit into the inner chamber, thence to the outer chamber, and then exits to the atmosphere at the front of the outer chamber. Each chamber has longitudinal lines of sight between front and back sound reflectors (R1-R2, R3-R4), and no longitudinal line of sight from the back reflector (R2, R4) to the atmosphere. The gas path through the suppressor is at least 6 times less flow-restrictive than the gas path through the bullet exit (17) or back into the barrel bore (4), minimizing backpressure. The gas path (P3) between the inner and outer chambers is through apertures (33) limited to a lengthwise middle portion of an inner shell (21) that divides the chambers (25, 29).

  • Patent number: 10488164
    Abstract: An improved firearm system is provided. The improved firearm system comprises an improved firearm cartridge for use in firearm designed to fire the improved firearm cartridge. The firearm cartridge comprises a projectile substantially seated within a cartridge casing, which reduces the length of the firearm cartridge. The cartridge casing may be modified to accept more than one primer. A firing pin of the firearm may be modified so it may strike each of the primers of the cartridge casing. A bolt body may be modified so that it has two pieces connected by a pin so that it may house the modified firing pin. Because the length of the firearm cartridge is reduced, the length of a magazine that holds firearm cartridges may also be reduced. This allows a handle of the firearm to be moved forward so that the magazine may be inserted through the handle.
