Abstract: A shoulder-launched multiple-purpose assault weapon having a modified spotter rifle with a top-mounted rocket launcher tube is provided. The spotter rifle forms the base structure of the weapon and all weapon controls are located on the spotter rifle. The spotter rifle has several dual-function mechanisms which perform the combined functions of assembly and safing, bolt-locking back and cartridge ejecting, simultaneous adjustment of both open and optical sights, firing, selectively, of both the spotter round and the rocket round. The combination of these dual-firing mechanisms provides a lighter weight, better-balanced and smaller weapon. The reduction in parts count improves reliability and lowers cost. Other improved features include an adjustable spotter rifle barrel used to match the boresight of the rocket tube and an improved locking mechanism. A dual function trigger assembly operated two sears from a single trigger.

Abstract: A shoulder-launched multi-purpose assault weapon with a removable rocket tube and spotter barrel is provided. The rocket tube and spotter barrel assembly is a standard receiver and trigger assembly. The grouping of the tube and barrel in a single removable assembly allows quick field replacement for either repair or reconfiguration of the weapon to a different rocket size. The sight assembly is also removable by sliding the sight out of dovetail attachment points. A further benefit is that different rocket tube assemblies may be pre-boresighted at the factory, thereby also reducing field assembly time.

Abstract: A single trigger dual firing mechanism having dual sears and dual hammers provided. A pivoting connector link is mounted on a trigger with a horizontal pin. A selector bar causes the connector link to rotate to either engage the primary or secondary sear. Engagement of one sear locks the other sear and locks out the opposite hammer. When the selector turns and engages the primary sear then that sear is moved and the primary sear allows the primary hammer to fall. With the selector knob in the opposite position, the secondary sear is operated allowing the secondary hammer to move. The primary hammer is a swing type hammer. The secondary hammer is a piston type hammer. Both hammers operate from a single trigger using a thumb operatable selector bar.

Abstract: A mechanism for providing fine adjustment to achieve parallelism of a spong rifle barrel and a launcher tube is provided. The mechanism uses a convex spherical or near spherical surface on the rear of the spotter barrel which is mated to a concave conical surface on the spotting rifle receiver. The receiver is rigidly affixed to the launcher tube. The spotting rifle barrel axis is adjusted by means of three adjustment screws which act on a locating washer attached to the muzzle of the rifle. The locating washer has a spherical or near spherical surface whose radius center is co-located with the radius center of a second spherical surface supporting the breech end of the barrel. These spherical surfaces permit the free pivoting of the barrel about the common radius centers. A barrel gripping collar is moved into contact with the locating washer by means of a spring which forces the convex conical surface of the locating washer to engage the concave conical surface of the grip collar.

Abstract: A combination bolt lock and cartridge ejector mechanism for a small arm is rovided. The mechanism has a hollow cylindrical bolt lock having slots cut through the cylinder and having beveled shoulder on the bolt engaging end. The cartridge ejector is also slotted and fits inside the hollow bolt lock. A single spring inside the bolt lock operates both the bolt lock and the cartridge ejector. A retaining pin secures the mechanism together and provides a means for attaching the mechanism to a receiver of a small arm.
