Abstract

The disclosure is directed at a blank fire bullet trap attachment (BFBTA) that provides improved protection for firearm users when live ammunition is accidently loaded into the firearm. The BFBTA includes a barrel portion made of a first metal; and a hardened element portion made of a second metal, the hardened element portion sized to frictionally fit within the pipe portion; wherein the first metal is softer than the second metal, such that when live ammunition contacts the hardened element portion, the hardened element portion slides within the barrel portion.

Abstract

A method and system for an inductively powering rail on a firearm to power accessories such as: telescopic sights, tactical sights, laser sighting modules, and night vision scopes. This is achieved by having primary and secondary electromagnets (U-Cores) on both the inductively powering rail and the accessory. Once the electromagnets are in contact, the accessory is able to obtain power through induction via the inductively powering rail. Accessories may be attached to various fixture points on the inductively powering rail and are detected by the firearm when attached and detached. When attached, power and data communications may flow between the accessory and a master CPU located on the firearm. Accessories that are attached to the inductively powering rail and have rechargeable power systems may be recharged via the inductive power rail. Further, accessories that have power that is not needed may be transferred to other accessories.
