Barrett-Havoc is a variant of the Barrett featured in CrossFire: Legends.
This gun features a new black Born Beast skin with red eyes, enhanced reload and bolt cycling time, and 15 rounds magazine (+5). Uniquely, Barrett-Havoc has a very low recoil when hard-scoping, as the gun swings back very little, unlike other Barretts, but otherwise its bolt cycling delay time is pretty much the same.
It also features a different scope design with clearer view, giving players more visibility to scope out enemies, plus a "vision scope" that makes the outer area semi-transparent instead of pitch black like other Sniper Rifles.
When equipped with DE-Havoc and Keris-Havoc, the Barrett-Havoc will feature another effect, custom zoom level. When using the scope, a slider will appear, allowing players to zoom in/out freely and more precisely.
