The R4 is a 5.56mm assault rifle that was introduced into service with the South African Defence Force (SADF) in the early 1980s, replacing the earlier 7.62mm FN FAL rifle, that was manufactured in South Africa under a license agreement from Fabrique Nationale as the R1. The R4 is produced by Vektor (a small arms division of Denel corporation, currently Denel Land Systems).
The weapon is a licensed variant of the Israeli Galil ARM assault rifle[1][2] with several modifications; notably, both the stock and magazine are now made of a high-strength polymer and the stock's arms were lengthened, adapting the weapon for the average South African soldier.[1]
Design details
Operating mechanism
The R4 is a selective fire, gas-operated weapon that fires from a closed bolt. As with the Galil parent weapon, the operating system is derived from that of the AK-47. It uses ignited powder gases channeled through a vent in the barrel to drive a long stroke piston located above the barrel in a gas cylinder to provide power to the operating system. The weapon features a self-regulating gas system and a rotary bolt breech locking mechanism (equipped with two locking lugs), which is rotated by a helical camming groove machined into the bolt carrier that engages a control pin on the bolt. Extraction is carried out by means of a spring-loaded extractor contained in the bolt and a protrusion on the left guide rail inside the receiver acts as the fixed ejector.
Features
The R4 is hammer-fired and uses a trigger mechanism with a 3-position fire selector and safety switch. The stamped sheet steel selector bar is present on both sides of the receiver and its positions are marked with letters: "S"— indicating the weapon is safe, "R"—single-fire mode ("R" is an abbreviation for "rapid"), and "A"—fully automatic fire. The "safe" setting disables the trigger and secures the weapon from being charged.
The R4 is fed from a synthetic box magazine with a 35-round cartridge capacity (designed to use the 5.56x45mm NATO cartridge with the M193 projectile) loaded in a staggered configuration. The flash suppressor is slotted and doubles as an adapter for launching rifle grenades. Bolted to a bracket in the gas block, under the barrel, is a lightweight folding bipod (folds into the handguard), which can also be used as a wire cutter.[1]
The R4 has a side-folding tubular stock, which folds to the right side of the receiver. The rifle's handguard, pistol grip, magazine, stock arms and shoulder pad are all made from a synthetic material, making it lighter in weight than the equivalent original Galil model which uses heavier metal and wood in these components.
For regular field maintenance and cleaning, the firearm is disassembled into the following components: the receiver and barrel group, bolt carrier, bolt, return mechanism, gas tube, receiver dust cover and magazine.
Sights
The rifle has conventional iron sights that consist of a front post and a flip-up rear sight with 300 and 500 m apertures. The front sight is adjustable for windage and elevation and is installed in a durable circular shroud. The rear sight is welded at the end of the receiver's dust cover. For nighttime use, the R4 is equipped with self-luminous tritium light dots (exposed after placing the rear sight in an intermediate position) installed in a pivoting bar to the front sight base, which folds up in front of the standard post and aligns with two dots in the rear sight notch.
Accessories
The R4 is issued with spare magazines, a cleaning kit and sling.
Variants
The South Africa Marine Corps and South African Air Force adopted a short carbine version of the 5.56 mm Galil SAR, which was license-manufactured as the R5. The R5, when compared to the larger R4, has a barrel that is 130 millimetres (5.1 in) shorter, together with a shorter gas system and handguard. It also lacks a bipod, and the flash hider does not support rifle grenades.
In the 1990s, an even more compact variant of the R5 was developed for South African parachute infantry and armored vehicle crews, designated the R6, which has a further reduced barrel and a shortened gas cylinder and piston assembly.
Vektor also introduced a line of semi-automatic variants of the R4, R5 and R6 called the LM4, LM5 and LM6 respectively, built for civilian and law-enforcement users. Newly manufactured models include a top Weaver rail for optics.
Users
- Haiti: used by the Haitian National Police
- South Africa: Standard issue rifle of the South African National Defence Force. The compact R5 carbine is popular among police and special response units.[3]
