Trivia

 * Other players can also hear the lock-on sound.
 * This is the first sniper weapon that can instantly kill an enemy even being shot in the leg.
 * Even if all rounds have been shot, the player would still reload the rifle. This happens since the reload animation is attached to the shooting.
 * The word "RG2" can be found on the buttstock. It is a possible acronym for Rail Gun 2.
 * The scope doesn't detect NPCs.
 * In Singapore/Malaysia region, when players fire at solid objects such as walls, there will be a circled B sprayed at the spot where it was fired at (see Gallery). However, this bug was fixed in later updates.
 * It also happens to Taiwan/Hong Kong region, but there will be an arrow instead of circled B.
 * In Indonesia region, players can obtain this weapon from Code Box although there was no official announcement yet. This also happens to StG 44 Gold.
