  • Lockable snap-clip fastener
    Patent number: 9500438
    Abstract: A lockable snap-clip fastener (10) has two spring-biased jaw members (12, 14) and a slidable locking bar (16). The same spring (13) that biases the jaws (12, 14) holds the locking bar (16) in either an open or a closed position with one of its arms. Since the bar (16) is held in either the locked or unlocked position, it is more secure and must be positively actuated in order to transition from one configuration to the other.

  • Weapon magazine
    Patent number: 9383152
    Abstract: A system and method for using a firearm magazine are described. One embodiment includes a firearm magazine assembly. The assembly has a polymer housing and a follower assembly comprising a follower, a spring, and an insert. The assembly also has a floorplate removably engaged with the proximal end of the housing and the insert. The follower assembly comprises a compressed configuration and an extended configuration relative to the housing, a compression limiter, and an extension limiter.

  • Ammunition magazine
    Patent number: 9347720
    Abstract: A new interface for a magazine follower and floor plate is used to provide greater stability to the round stack and a more sturdy system overall. The floor plate is designed with two opposite legs, the rear being shorter than the front leg so as to facilitate travel throughout the magazine and clearing of accumulated dirt and debris. The floor plate, in one embodiment, utilizes a lock plate that is shaped and sized to become a shoe for the compressed spring and associated follower. In an alternate embodiment, the floor plate itself serves the purpose and, with provided teeth, directly fastens to the magazine casing at notches manufactured in the magazine wall for that purpose. Other enhancements to the magazine include at least one matrix of divots to provide a paint surface, an over-insertion stop and a lower rear geometry to aid in clearing debris and grit.
