Abstract

A linkless ammunition feed system for a firearm. The ammunition feed system has an ammunition container with a path for holding a plurality ammunition rounds in a single file manner and an exit for passing the ammunition rounds out of the container. A pusher is positioned in and adapted to freely slide through the ammunition path, the plurality of ammunition rounds being positioned between the exit and the pusher, the pusher adapted to push the ammunition toward the exit. The pusher is pulled through the ammunition path by a feed line connected to the pusher and extending through the ammunition path. A rotatable feed line spool collects the feed line at the container exit, and a feed sprocket rotates to move an ammunition round from the container exit to a firearm associated with the ammunition feed system.

IPC Classes  ?

• F41A 9/02 - Feeding of unbelted ammunition using wheel conveyors, e.g. star-wheel-shaped conveyors

Abstract

A recoil-operated, impulse averaging, air-cooled, magazine-fed, automatic weapon. An operating group of the weapon includes a chamber, a bolt, a barrel extension and one or more toggles. The recoil action of the weapon from firing a first round drives the toggles in a motion constrained by a cam way. The toggles then drive the chamber in a linear reciprocating motion ejecting a first round and over-riding the next round. An impulse averaging system controls the speed of the recoil.

IPC Classes  ?

• F41A 19/02 - Burst limiters
• F41A 3/00 - Breech mechanism, e.g. locks

Abstract

A weapon system is provided with a rotary lock bolt driven by a bimodal cam way.

IPC Classes  ?

• F41A 3/26 - Rigid bolt locks, i.e. having locking elements rigidly mounted on the bolt or bolt handle and on the barrel or breech-housing respectively the locking elements effecting a rotary movement about the barrel axis, e.g. rotating cylinder bolt locks semi-automatically or automatically operated, e.g. having a slidable bolt-carrier and a rotatable bolt
