Vektor LM4
Denel Land Systems (formerly Lyttelton Engineering Works) · Rifle · Out Of Production · 1990
Also known as: LIW LM4
Overview
The Vektor LM4 is a semi-automatic-only rifle chambered in 5.56x45mm NATO, developed by Lyttelton Engineering Works (later Denel Land Systems) as the civilian and law-enforcement version of the select-fire R4 assault rifle. Derived from the Israeli Galil ARM, it retains the R4's long-stroke gas-operated action, rotating bolt, chrome-lined 460 mm barrel and side-folding polymer stock, but is restricted to single-shot semi-automatic fire. The 'LM' designation reflects a Lyttelton-Musgrave marketing arrangement for the sporting line.
