20210254933 | METHODS AND APPARATUS FOR OPTICAL ADAPTER FOR FIREARM SLIDE - An apparatus and method for modifying a handgun to accept an optical sight comprises and modified slide mechanism adapted to include a flat recessed rear section configured to receive an adapter plate for mounting an optical sight. Various embodiments of the adapter include modified internal components used to replace stock components what will no longer fit within the modified profile of the slide mechanism. Replacement of the slide mechanism and associated internal components will allow a user to add an optical sight to an existing handgun. | 2021-08-19 |
20210254934 | DEPLOYABLE BALLISTIC SHIELD - A deployable ballistic shield is disclosed. The deployable ballistic shield includes a plurality of layers formed of a high impact anti-ballistic Aramid material. The shield is selectively configured between a stowed condition, in which the plurality of layers are in contact with an adjacent layer, and a deployed condition in which the plurality of layers are suspended in a spaced apart relation with a gap formed between the adjacent layer. A handhold is defined at a top end of the shield. Aa foothold may be defined at a bottom end of the shield. The deployable ballistic shield may be used by law enforcement, military, and other personnel as a protective ballistic barrier. Gaps between the plurality of layers serve to absorb the kinetic energy of a ballistic round. | 2021-08-19 |
20210254935 | Civilian Bullet-Proof Shield - A shield has a rectangular body, a first rollerball bearing assembly mounted in a first bracket joined to the body, such that the first bracket extends away from the left vertical edge of the body, a second rollerball bearing assembly mounted in a second bracket such that the second bracket extends away from the right vertical edge of the body, and the spacing between the first and the second rollerball bearing assemblies is greater than the width of the body. The body rests on the rollerball bearing assemblies when standing and a user, is enabled to hold the shield oriented vertically and to move the shield side-to-side, and the user is further enabled to tilt the shield back toward the user, transferring support to wheels rather than the rollerball bearing assemblies, and is then enabled to move the shield forward and backward on the wheels. | 2021-08-19 |
