Z-M Weapons LR-300 Assault Rifle U.S.A

The LR-300 assault rifle was developed by Z-M Weapons, a small US-based company. This rifle was
designed by Allan Zitta and is aimed at law enforcement personnel and special operations forces. It is a version of the M4 carbine. The designation LR-300 translates as Light Rifle with a range of effective fire in 300 meters. It was manufactured between 2000 and 2007. Later all rights for the design were sold to Para USA. The LR-300 is a gas operated, selective fire rifle. It is a state-of-the art compact modular weapon, based on the M16 design. The LR-300 has an improved patented gas operating system.

The main reason for this modification was to provide this rifle with capability to mount side-folding stock, rather than fixed M16-type stock, or partially collapsible M4 carbine-type stock. None of these stocks could be removed due the spring piston, mounted inside. A patented gas system of the LR-300 allowed to make the stock collapsible. It is fitted with the FN FAL-type non-adjustable or adjustable telescopic side-folding stocks. As a result the LR-300 is significantly shorter, but reduced size do not comes at a price of reduced accuracy.
