The Ka'chak'tarr is an ornate Kroot Shaper Rifle, that is a relic of the species.
The weapon is beautifully balanced and has such precision marksmanship, that it only renders the violent detonations of the Ka'chak'tarr's shots all the more shocking. The Kroots' legends also state the Rifle has consumed numerous weapons, just as they devour their foes. Like them, the Ka'chak'tarr gains ever more power and poise from each supposed feast.
