The Assault Rifle, also known as the AK or AK47u, is a high-powered rifle to be feared, and is extremely popular in late-game Rust for its versatility. The AK outperforms every other weapon in the game at short to medium range, and for those who have mastered the spray it can also be highly accurate and lethal at long range, competing with the Bolt-Action Rifle and L96 Rifle because of its high rate of fire.
The AK has the most skins out of any other item in Rust due to its popularity. The skins range from small cosmetic differences, all the way to stockless or with glowing iron sights, making it much easier to use in Rust's dark nights and offering a significant competitive advantage. Because of this advantage, Facepunch have decided that they will no longer accept new glow sight skins into the game, making the current ones exceedingly rare.
