The LWRCI Legacy PSD pistol gives you rifle fire power in a package size usually reserved for sub machine guns. The pistol is outfitted with our full quad rail system. The carbine length rail over a low profile gas block gives the operator their choice of in rail mounted BUIS and is ideal for optic and other rail mounted accessories. As with all LWRCI rifles, the top rail comes off with-out the use of tools, to make our self-regulating piston system serviceable, while delivering repeatable zero. The PSD pistol has all the features of a rifle except the standard buffer tube and stock have been replaced with a shortened recoil system. Being classified as a pistol allows the end-user to take it home sooner by not having to wait for a form 4 to clear. This configuration is a pistol, the addition of a stock or a forward pistol grip requires prior approval from the BATFE for the creation of a SBR.
