A piston/rocket projectile for use within a launcher system having a barrel and method of firing such are presented herein. The projectile comprises a projectile body having a combustion chamber for propellant, a piston moveable to extend out a base of the projectile as a result of ignition of propellant in the combustion chamber, and vents for expulsion of combustion products from the ignition of propellant out of the projectile base after initial movement of the piston. A casing is secured to the base of the projectile body, enclosing the piston and vents prior to the ignition of propellant, and a frangible joint is disposed between the casing and the base of the projectile body. Upon ignition of propellant in the combustion chamber, the projectile piston is forced against the casing and causes the frangible joint to break, leaving the casing in the barrel. After the piston completes exertion of propulsion force against the casing, combustion products of the ignition of propellant are expelled through the vents out of a lower end of the projectile and solid combustion byproducts from the ignition of the propellant are collected in the casing.

A medium caliber round of ammunition capable of being fired at variable velocities and trajectories, and methods of firing such, are presented herein. The ammunition round includes a grenade and a cartridge received in a firing chamber. The cartridge has a front case for receiving the grenade, and a rear case for receiving a primer. An adjustable variator collar is disposed between the front and rear cases. The variator collar is adjustable between a first position that chokes the venting of gas from a high-side stage to a low-side stage for low muzzle velocity, and a second position for un-choking the venting of gas from the high-side stage to the low-side stage for a rapid rise in pressure during the low-side stage, resulting in a high muzzle velocity. The collar may further be adjusted in any position between the first and second for relative amounts of controlled fluid flow.

A rifle comprises a quad lock multicaliber receiver, a barrel extension, a bolt, and a projection engageable with the receiver. The barrel extension includes a cartridge chamber and is securable in an end of the receiver. The bolt is slideable in the receiver and engages a cartridge in the cartridge chamber during the firing phase. The projection comprises locking bars extending through the receiver, and is moveable between locked and unlocked positions to allow for securing and removing of the barrel extension, respectively. Positioning bars are disposed on either side of the receiver split parallel to its longitudinal axis. The locking bars are disposed between these positioning bars and the barrel extension such that when the positioning bars are urged toward each other the receiver split is closed and the positioning bars urge the locking bars toward and into locking grooves to secure the barrel extension in the receiver.

A lightweight rifle has a chassis with a forward receptacle and rear receptacle, a forend tube with a male key, a barrel, a breech, a spacer, a trigger guard, a grip, and a butt stock adapter. The barrel and breech connect along a shared longitudinal axis, and the resulting subassembly inserts into the forend tube. The spacer secures the connection between the breech and the forend tube with a combination of scope screws and rivets that extend through the forend tube, spacer, and breach, respectively. This forend tube subassembly connects to the chassis by inserting the forend tube male key into the chassis forward receptacle and further securing the male key and forward receptacle together with bolts. The butt stock adapter has a protruding male key and mates to the chassis rear receptacle. This allows for the quick and secure connection of a butt stock to the rifle chassis.

A rifle has a receiver, a cartridge chamber connected to the receiver, and a bolt slideable longitudinally in the receiver, the bolt is engageable with a cartridge in the chamber. A bolt carrier is slideable longitudinally in the receiver to move the bolt into and out of engagement with a cartridge in the cartridge chamber, and a bolt handle is connected to the bolt carrier. The bolt handle is positionable in a manual position extending from one side of the rifle to permit manual firing of the rifle and in a semiautomatic position about 180 degrees different from the manual position and extending from the other side of the rifle to permit semiautomatic firing of the rifle. The position of the bolt carrier may be changed between the manual and semiautomatic positions without removing the bolt carrier from the rifle.

A rail mounting system for a firearm includes a shroud on the fore end having a plurality of spaced rectangular pads with raised, rectangular top surfaces and opposed sloping sides forming an opposed pair of side walls that intersect with the shroud surface at an acute angle. The rail mounting system also includes a mounting rail having spaced apart relief sections conforming to the locations of the pads with recessed rectangular relief bottoms and opposed sloping sides forming an opposed pair of angled side walls at the same angle as the pad side walls. The side walls of the pads and relief sections are in contact with each other along at least some of their vertical distances. The pad top is spaced from the relief bottom and the shroud surface is spaced from the rail underside.
