PC Equipping this weapon will cause it to be permanently locked in the player's inventory, as it is an item that cannot be dropped or replaced with another weapon.

With the Better Criticals perk, this weapon actually does less damage than the standard anti-materiel rifle as the critical damage bonus of this weapon is significantly less than that of the standard rifle.

It will appear in the Pip-Boy as 'anti-materiel rifle,' but it cannot be stored or picked up if dropped this is due to it being marked 'non-playable.'.

It will not be obtainable from the sniper wielding it even if killed, as he will drop a normal anti-materiel rifle, and his corpse will still be holding this one. The Ratslayer, found in Broc Flower Cave, also deserves a honorary mention for being an easily accessible, scoped gun that silently shoots 5.56mm rounds. The Oliver anti-materiel rifle can only be obtained via console commands. You may also wish to look into the sniper rifle's bigger brother, the anti-materiel rifle, or the unique Christine's CoS silencer rifle if you have Old World Blues. The Oliver anti-materiel rifle can fire a total of about 870 standard rounds, the equivalent of 109 reloads, from full condition before breaking.

However, the player not only needs to be serving the Legion to access Oliver's compound, but they need to fail the Speech checks against General Oliver to explore the cell in which the sniper holding this weapon is found. It is used by an NCR sniper at Hoover Dam during the final battle, if the player is working for Caesar's Legion. It functions very much the same as the standard anti-materiel rifle with increased damage, health and no spread but decreased critical hit damage bonus.
