Appearance
«Accuracy International L115A3» is a large sniper rifle that is about as long as PGM Ultima Ratio Hecate II, though it is slimmer than Hecate. It has several bolt holes that pass through the mechanisms, a highly-advanced grip that has a thumb handle and a polished dark-gray body. The most unique aspect about the weapon is that it is designed to be used with a suppressor that allows the user to snipe targets 2,000 meters or more way without being heard or seen.

Phantom Bullet Arc
On December 14, at around 8:40 pm during the 3rd Bullet of Bullets, Sterben used the sniper, loaded with electrical stun bulets, to shoot Pale Rider, momentarily stunning him so that Sterben could get closer to use his Type 54 "Black Star" to stage a real life murder being done via a game.

A bit more than 15 minutes later, Sterben shot Sinon with a stun bullet as she was moving through a hole in a collapsed tower's wall. He then attempted to shoot Sinon with his Black Star from up-close, but his attempt was interrupted by Kirito. Sterben quickly changed back to his sniper and reloaded it with regular .338 Lapua bullets for a sure kill, firing at Kirito afterwards. Although the bullet hit its mark, it only grazed his shoulder, thus did not deal enough damage to kill him.

About 30 minutes later, Sterben used the sniper to shoot at Kirito who was out in the open as bait, however, Kirito barely managed to dodge the bullet after sensing a "killing intent". After Sinon killed Yamikaze with a sniper bullet, thus revealing her position, both of them fired at each other with their snipers. Sterben's bullet missed Sinon and instead hit her Hecate's scope, destroying it in the proccess, while Sinon's large caliber bullet hit the L115A3's weak spot directly, shattering the sniper into its components and destroying the mechanism part of the sniper completely.
