Design details
The gun was designed to be a personal security detail pistol. The LWRC pistol accepts a 5.56 NATO cartridge. It has a 8.5 in (22 cm) barrel and weighs 5.9 lb (2.7 kg) pounds. The gun has the short-stroke gas piston system. The barrel has a 1:7 twist and is treated with Black Nitride.[2]
Operation
The PSD is an AR-15 style pistol which uses the same platform as the AR-15. The platform allows uppers to be switched and the lower receiver is the same specifications as the AR-15.[3] It is fitted with LWRCI's flip-up iron sights and the controls are ambidextrous. The gun has MIAD pistol grip and the trigger pull measures 7.5 pounds. Because of the way the gun can be easily concealed, it is used by security details.[4]
