  • Patent number: 11892267
    Abstract: The buttstock assembly uses a modular design including interchangeable end attachments and sling strap connectors. The interchangeable end attachments allow the buttstock to have different toe heights and configurations for different shooting applications. The interchangeable strap connectors allow the use of either quick-disconnect style sling swivels or more traditional fixed strap loops as desired. The buttstock assembly also uses a “trigger” style locking mechanism to selectively position and lock the buttstock along the length of the extension tube to adjust the overall length of pull of the weapon.

  • Patent number: 11287199
    Abstract: A slide devise for facilitating grasping and pulling a pistol slide rearward during various pistol operations. The slide device facilitates pulling back the pistol slide utilizing relatively little force. The device includes an adaptor and a rack plate interconnected by a sliding dovetail joinery. The adaptor replaces the traditional slide cover plates on conventional striker fired pistols. The rack adaptor has an integral interface shoe, which seats within a complementary channel in the rack plate. The rack plate has a pair of opposed side protrusions or wings that are configured to fit or be engaged by the fingers or hand of the user, so as to allow the user to easily pull the pistol slide rearward.
