It is, alongside its primary Covenant counterpart, the Type-50 particle beam rifle, the most accurate and arguably the most powerful small-arms weapon in either arsenal. The rifle features a barrel about 187.5cm long and is completely interchangeable.

Trivia

 * During an interview, William O'Brien, an animator for Halo 2, said, "Robert McLees is definitely the go-to guy for the gun stuff. I wanted to come up with an animation for the sniper scope, an 'idle cycle'. If you activate the scope, and then sit too long without doing anything, the animation would kick in periodically, just to keep things interesting... Simple, right...? He replied, 'No way. If you adjust your scope in the field, you're dead. Snipers don't do that.' That's how detailed his weapon designs are -- not just guns, but how they work, and how a sniper would fire them. Amazing."
 * In Halo: Combat Evolved, enemy NPCs do not acknowledge the sniper rifle's shot if they do not see the sniper, despite its loud crack in close-medium quarters. If the player downs an enemy with the sniper rifle, some will note the fallen AI, but will not search for the player as they would if the player fired with any other weapon. This can be most easily seen (and thoroughly used to the players advantage) during the opening sections of Truth and Reconciliation, and is essential to getting the All According to Plan achievement in Halo: Anniversary
 * In the original Xbox 360 version of Halo: Combat Evolved Anniversary the sniper rifle's reticule is far larger than it is in the original Halo: Combat Evolved on Xbox and PC. In the Halo: The Master Chief Collection version of Halo: Anniversary, the reticule returns once again to its original size.
