The Vektor R4 is a 5.56×45mm assault rifle designed in 1979 based on the IMI Galil rifle. It entered service as the standard service rifle of the South African Defence Force (SADF) in 1980. The R4 replaced the R1, a variant of the 7.62×51mm FN FAL.

The weapon is a licensed variant of the Israeli IMI Galil assault rifle with several modifications; both the stock and magazine are now made of a high-strength polymer and the stock was lengthened, adapting the weapon for the average South African soldier.

The South African Navy, South African Air Force, South African Military Health Service, and South African Police Service 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 personal defence weapon variant of the R5 was developed for armoured vehicle crews, designated the R6, which has a further reduced barrel and a shortened gas cylinder and piston assembly. This reduced the barrel length to 279 millimetres (11.0 in).

The file pack there includes all 3 versions – R4/R5/R6 with accessories of Picatinny rail, 2 variations of ACOG scope, AIMPOINT red dot, and supressor, in total of 30 variants. The scale may be a bit big for truescale 1/56 models, so you can scale it appropriately in slicer.

These models were designed for tabletop gaming, so some details are rather enlarged or missing for sake of good and safe printing and use. Models also were test printed on Elegoo Mars 2. Model is intended for resin printing due to fine details, 0.02 layer height is highly recommended.
