A firearm bolt locking mechanism includes a locking pin in the bolt carrier of a firearm like an AK-47 assault rifle or variant thereof. The locking pin is normally urged from the bolt carrier by a compressed spring. The mechanism also includes a pivot arm mounted on the receiver cover of the firearm. The pivot arm has a spring-biased finger that normally fills a hole in the receiver cover. The mechanism further includes a magazine that stops the bolt of the firearm when the last cartridge from the magazine is fired and permits the spring to drive the locking pin into the hole. After replacing the empty magazine with a full one, the pivot arm is pressed to replace the locking pin in the hole with the finger and to release the bolt carrier to chamber a cartridge.

Bullet Deflection, Fighting Position Body Armor incorporates a novel bullet defeat mechanism approach different than conventional armor's objective of stopping bullets. Many rifle bullets that are used for military assault rifles are designed to turn or tumble on contact allowing maximum energy to be imparted on the target in minimal penetration distance. Exploiting this bullet / rifle design, deflecting bullets becomes a new attractive solution rather than stopping bullets because significantly less weight required to deflect an "unstable" bullet. Fighting position body armor can be mounted on the user's arms, shoulders and helmet. These locations are not normally protected by conventional body armor thereby providing significant protection when the soldier is in firing / fighting positions. Designs can be made to integrate the Bullet Deflection, Fighting Position Body Armor areas of protection with conventional body armors to optimize weight and areas protected.
