  • Patent number: 9829274
    Abstract: A firearm includes a forend having a forend body attached to the firearm below a barrel, and a cord removably secured to a gripping surface of the forend body. The forend body is provided with at least one groove removably receiving the cord to secure the cord to the forend body. The groove is configured to receive the cord therein such that a portion of the cord extends out of the groove so that the slip resistance of the gripping surface of the forend body is improved. The cord can be easily removed from the groove of the forend body whenever the user of the firearm desires to use the cord in any other suitable manner.

  • Patent number: 9821752
    Abstract: The invention relates to a hybrid inflator (10) including a burst cap (20) including a bottom (21) and a sleeve-like side wall (22), the bottom (21) and the side wall (22) delimiting an igniter compartment (23), and the burst cap (20) in the idle mode being pressurized on the outer peripheral side with compressed gas having a filling pressure (PF) which at a functional maximum temperature of the hybrid inflator (10) has a maximum filling pressure (PFmax), and wherein the burst cap (20) can be destroyed by an igniter compartment side bursting pressure in the case of operation. In accordance with the invention, a transitional portion (24) is formed from the side wall (22) of the burst cap (20) to the bottom (21) so that the igniter compartment side bursting pressure required to destroy the burst cap (20) is lower than the sum of the maximum filling pressure (PFmax) and the filling pressure (PF).

  • Patent number: 9810496
    Abstract: A semiautomatic firearm with redundant systems for reducing misfirings. A safety trigger is provided that is passively actuated in advance of a firing trigger. The safety trigger maintains redundant safety mechanisms that prevent inadvertent or accidental actuation of the firing trigger. The firing trigger can be configured for actuation with a very low magnitude or “soft” pull without compromising safety. For the disclosed embodiments, the safety trigger assures that the firearm is discharged only upon deliberate actuation of the firing trigger. In one embodiment, a trigger pull adjustment mechanism provides adjustment of the pull of the firing trigger to a desired force required by the operator. The disclosed trigger pull adjustment mechanism reduces the number of components and complexity of the machined parts over conventional trigger pull adjustment mechanisms.

  • Patent number: 9791225
    Abstract: The charging handle assembly uses a magnetic latching mechanism to replace the spring loaded latch mechanism common on conventional M16/AR-15 style weapons. The magnetic latching mechanism consists of magnetically attracting plugs mounted to or within the upper receiver and the charging handle. The magnetic attraction between the adjacent plugs provides the locking force to secure the charging handle in the closed position while still allowing the user to manually pull the handle to the open position when necessary.
