| 20100037760 | Method and apparatus for muzzle lift compensation - A method and apparatus counteracts the muzzle lift of a firearm resulting from recoil, and a firearm has an integral counteracting structure. A port extends from an inner surface of the firearm barrel bore to an outer surface of the barrel, forward of the location that the propellant ignites, to an occluding structure located beneath the grip surface of the firearm. When the propellant is ignited, and the projectile passes the relief port, a portion of the propellant gas exits the bore prior to the muzzle end, travels through the propellant gas relief tube, and exerts a force on the occluding structure. The force acts downward on the firearm, counteracting the recoil-induced muzzle lift. | 02-18-2010 |
| 20100175548 | METHOD AND APPARATUS FOR THE REDUCTION OF MUZZLE JUMP IN FIREARMS AND WEAPONS - Muzzle jump of projectile-firing guns and weapons systems is significantly reduced by creating a momentum, rotating in the direction opposite to the rotational direction of the momentum causing muzzle jump by redirecting not a gas flow produced by a blast of ammunition but redirecting a projectile traveling through the barrel. The barrel is bent in such a way that curvature of the bend is made convex in relation to the support of said gun or systems. The plane of said curvature coincides with the plane of the momentum created by recoil of the said gun or system. Since the projectile possesses significantly bigger mass than escaping gases, the created contra-momentum is much bigger than the one which could be achieved by redirecting a flow of escaping gases so it could be sufficient to completely negate momentum created by recoil force of said projectiles firing gun or weapon system. In preferred embodiment there is an attachable device which allows adjustment of the bend angle by rotating a skewed extension of the barrel in the skewed cylindrical opening of said attachable device's housing. Said device can provide relatively inexpensive implementation of the suggested concept. It is understood that the aiming system of the weapon needs to be realigned to accommodate probable change in the trajectory of the projectile. | 07-15-2010 |
| 20100180758 | EXTREME CHOKE - Disclosed is a manifold device containing two equidistant manifold openings which adapt to shotgun chokes to counteract muzzle rise, felt recoil, and muzzle blast in addition to the selectable shotgun choke which controls the shot pattern. The two manifold openings are located in the upper 180 degree portion of the manifold to counteract forces by discharging gases substantially upwards and backwards. A manifold saddle with sufficient curvature for accommodating a second barrel can be utilized for double barrel weapons. The manifold is held in place to maintain the upper 180 degree direction by a choke stop, clamp, or other attachment. | 07-22-2010 |
| 20100224054 | MUZZLE BRAKE AND METHOD - A muzzle gas reduction device has upper and lower elongated, curved sections that define a barrel shape that is open to the sides. The upper section has a narrower width than the lower section. A plurality of cone-shaped, open, combs are interposed between the upper and lower elongated sections, along a length thereof. The device is coupled to the end of a barrel of a firearm, preferably a PAN disrupter. The configuration of the cones and the differing widths of the upper and lower sections cause muzzle gasses to be re-directed rearward and upward, reducing recoil. | 09-09-2010 |
