Abstract:
In an open chamber air gun, a round is gravity fed or magnetically fed into the open chamber and falls into the magnetic flux lines of a magnet disposed at the chamber. Due to the magnet, the round is pulled securely into the chamber and then remains momentarily held in place, blocking much of the air behind it and thus increasing the air pressure driving it. When the round moves down the barrel from the breech toward the muzzle, it quickly leaves the vicinity of the magnet and the magnetic drag ceases, after which the air pressure is free to drive the round to full velocity. High rates of fire and muzzle velocities are achieved with moderate air pressure and an action with no moving parts.

Claim (Index 1):
An air gun for use with a plurality of rounds of magnetically responsive spherical ammunition having a caliber, the air gun comprising:\n a source of pressurized air; a hand grip having a first end and a second end, the first end of the hand grip being connected to the source of pressurized air, and the hand grip having a first passageway therethrough from the first end of the hand grip to the second end of the hand grip; an air feed line having a first end and a second end, the second end of the hand grip being connected to the first end of the air feed line, the air feed line having a second passageway therethrough from the first end of the air feed line to the second end of the air feed line; a gun barrel having a muzzle and a breech end, the second end of the air feed line connected to the breech end of the gun barrel, the breech end having an aperture; a magnet disposed at the breech end of the gun barrel whereby the magnet exerts magnetic force within the breech end of the gun barrel, the magnet being spaced from an inner surface of the gun barrel so as to not extend into the air flow conduit, the magnet being located opposite the aperture; and a gravity feed disposed above the aperture, wherein the gun barrel, the first passageway, and the second passageway form a continuous air flow conduit, wherein the breech end of the gun barrel and the second end of the air feed line are magnetically non-responsive materials, wherein the gravity feed, the aperture, and the gun barrel having respective inner diameters larger than the caliber, and wherein the magnet influence is sufficient to chamber a first round of the plurality of rounds by holding the first round of the plurality of rounds in the breech end below the aperture until the air pressure expels the first round from the muzzle.
