Abstract: Present embodiments relate to a modular firearm. More specifically but without limitation, present embodiments relate to a modular firearm, for example semi-automatic rifle, with various modules that provide differing functions to a semi-automatic or automatic rifle. Some of the functions include, but are not limited to, connector for ambidextrous stock folding, interchangeable magwell for changing of firearm caliber, a barrel module with evacuation chamber, and ambidextrous charging handle.

Abstract: Compositions with supramolecular structures for use in agricultural methods include a source of macronutrients such as a fertilizer, a supramolecular host chemical or a supramolecular guest chemical configured to engage in host-guest chemistry with the source of macronutrients, and a solvent. Formulations for combination with a macronutrient source are also included. Methods of treating a plant to improve nutrient assimilation or vigor include applying an agriculturally effective amount of the composition to the plant.

Abstract: A firearm suppressor that includes a mount configured to connect the firearm suppressor to a barrel of a firearm. The firearm suppressor includes a first module connected to the mount. The interior of the first module is a first chamber and the first module does not include a baffle. The firearm suppressor includes a second module connected to the first module. The second module includes a plurality of baffles and at least one peripheral pathway that bypasses a second baffle of the plurality of baffles by fluidly connecting an exterior of a first baffle of the plurality of baffles with an exterior of an exterior of a third baffle of the plurality of baffles. The firearm suppressor includes an end cap connected to the second module.

Abstract: A multi-core suppressor for a firearm. The multi-core suppressor includes a housing having a first and second ends and a central main core positioned within the housing. The central main core has a first end, a second end, and a longitudinal centerline with a plurality of central baffle portions positioned adjacent to the longitudinal centerline and a projectile path through the central baffle portions. The multi-core suppressor includes a first side core positioned between the housing and a first side of the central main core and a second side core positioned between the housing and a second side of the central main core. The first side core has a plurality of first side baffle portions and the second side core has a plurality of second side baffle portions. The first and side baffle portions engage the central baffle portions to form a plurality of baffles positioned within the housing.

Abstract: A firearm sound suppressor and associated methods. The suppressor can include first and second firearm connectors at opposite ends of the suppressor for connecting to firearm mounts of different types. The suppressor can include symmetrical baffling and/or symmetrical gas flow passaging such that sound reduction performance of the suppressor is generally the same notwithstanding whether the first or second firearm connectors is used to connect the suppressor to the firearm. A protector can be used to protect the firearm connector that is not connected to the firearm.

Abstract: A firearm sound suppressor and associated methods. The sound suppressor includes a distal end wall and a flash hider on the distal end wall for reducing flash at an outlet of the suppressor. The sound suppressor can include a core including gas baffling integrally formed with the distal end wall and the flash hider. The flash hider can include a plurality of arms having slots therebetween and extending distally away from the distal end wall.

Abstract: A suppressor assembly for a firearm including a barrel, a bore and a muzzle end. The suppressor assembly may include a gas block mount positioned about the barrel, and outer tube configured to be attached to the gas block mount, and a baffle configured to be attached to the muzzle end of the firearm. The baffle is telescopically received and configured to have a clearance fit with the outer tube. The baffle may also include one or more outer edges configured to scrape debris from the inner surface of the outer tube when the baffle is removed from the outer tube.

Abstract: A quick connect for a pistol suppressor includes a housing having a first end, a second end, and a central bore with an upper portion, a lower portion, and an internal shoulder separating the upper and lower portions. A piston is within the central bore of the housing. The piston includes a piston shoulder that creates an upper recess within a central bore of the piston. A ring having a locking profile is selectively connected to the second end of the piston between the housing and the piston and a spring is positioned around an exterior of the piston. A wave spring is positioned in the upper recess of the piston adjacent the piston shoulder and a washer. A cap with a central opening and an internal locking profile is connected to the piston with the wave spring biasing the washer towards the locking profile.

Abstract: A monocore for a sound suppressor that significantly enhances the trapping and delay of the gases exiting from the sound suppressor due to the design, location, and configuration of slanted baffles and angled half-baffles, and a plurality of rods. The slanted baffles help define the blast chamber, expansion chambers, and exit chamber of the monocore. The plurality of rods may be positioned in the blast chamber or the expansions chambers. The plurality of rods may vary in length. The plurality of rods may also replace the angled half-baffles.
