Law enforcement carbine with one piece receiver
An indirect gas operating system for an M4 type automatic or semi-automatic firearm. The indirect gas operating system has a gas block having a cylinder. The gas block is fitted to a barrel assembly having a bore with the cylinder in communication with the bore. A piston having a piston end and a striking end has the piston end fitted to the cylinder. A bolt assembly having a striking surface is provided. When a cartridge is fired, gas displaces the piston end and causes the striking end to strike the striking surface displacing the bolt assembly. The cylinder and the piston are together removable as an assembly from the firearm without removal of the gas block.

A crossbow includes an elongated frame coupled to a riser at a first end thereof and attached to an upper housing at its second end generally above the trigger region. The riser supports a pair of flexible limbs, and a bowstring extends between such limbs. A bowstring retractor is provided within the upper housing and includes a rope spool used to wind a retractor rope for retracting the bowstring. First and second spool gears surround the rope spool for rotation therewith. A spur gear mounted on a drive axle engages one of the spool gears, and a crank can be engaged with the drive axle. A pawl engages the other spool gear to prevent unintentional unwinding of the retractor rope from the rope spool. A pawl release member disengages the pawl from its associated spool gear. Drawing the bowstring beyond its full draw position also disengages the pawl.

Paintball loader
A paintball gun loader. The loader is used in a closed-bolt paintball gun. The loader provides a paintball contact surface that moves in oscillating fashion in response to movement of the bolt to load individual paintballs into the gun while the gun loading port is open, which occurs as the gun cycles when fired. The loader includes a spring element that limits the force exerted on the paintball being loaded, even in case of a jam when the paintball contact surface is urged toward the paintball. In one embodiment, a pivotally mounted flexible lever arm having a paintball contact surface oscillates through an angular range of motion in response to a cam surface of the bolt engaging a cam follower on the the loader. In such embodiment, the cam follower is urged toward the cam surface of the bolt, which in turn biases the paintball contact surface toward an open, paintball receiving position.
