The Vektor is characterized by its highly-contoured look featuring smooth curved lines and a futuristic overall shape. The weapon is arranged in a "bullpup" configuration, meaning that the magazine feed is situated behind the pistol grip and trigger group (associated more commonly to the Austrian STEYR AUG universal automatic rifle). The grip and trigger unit are protected by a handguard running from the base of the pistol grip to just forward of the trigger. The body aft of the magazine feed is large and becomes the integrated buttstock, housing the weapon's cleaning kit. The body forward of the handguard becomes the integrated foregrip. The foregrip can be removed to accept underslung weapons such as a single-shot grenade launcher. Optics (1X magnification with illuminated reticle is standard) are mounted atop the weapon receiver while the cocking handle is situated just below this mounting. The barrel of the weapon protrudes some distance away from the forward body and sports a flash suppressor. Construction is of high-impact polymer.
The Vektor CR-21 is chambered to fire the universal 5.5x45mm NATO standard cartridge. The weapon is fed from a 35-round Vektor R4-type magazine. The firing action is gas-operated with a rotating bolt. Rate-of-fire is listed at 700 rounds per minute when in full automatic fire. Muzzle velocity is a reported 980 meters per second. The Vektor CR-21 weighs in at just 8.2lbs when fully-loaded. Overall length is 760mm with the barrel making up 460mm of this length.
The CR-21 has also been developed into a shortened carbine form.
