Ranger Sequoia

The  is a rare, scopeless variant of the Hunting revolver in Fallout: New Vegas.

Characteristics
This large revolver is carried only by the elite rangers. The writing along the barrel reads "For Honorable Service" on one side, and "Against All Tyrants" on the other. It is the unique version of the hunting revolver, and is modeled after the Magnum Research BFR (Biggest Finest Revolver), a real world .45-70 revolver.

On a side note, cannot be hidden when searched. (Not a Hold-out weapon)

Locations

 * It is owned by Chief Hanlon at Camp Golf, go in the resort home, go up the stairs and he is on the balcony. You can simply kill him to acquire the revolver but this does not always work . Because of Hanlon's bad ways you will not lose karma though you may lose enough reputation with the NCR to become shunned if you have not built any up before hand. Be warned however the other rangers will become hostile but if you simply wait on the balcony for around 20 seconds they will return to being friendly.
 * Can be obtained through the quest 'Return to Sender.' At the end, chose the option to turn Hanlon in. He will ask that you send an NCR Ranger to do the job, but as soon as you leave, he locks himself in. After a brief announcement, he will commit suicide, leaving you with the Ranger Sequoia to collect for yourself. Make sure to loot it from the ground as soon as you can. A ranger will come in to guard his corpse soon after. If one appears you may drag the gun to an empty room.  You can also complete the quest by agreeing to keep his secret, then killing him from sneak with a silenced gun and looting the revolver (does not lose karma or gain infamy).
 * Another method is to simply pickpocket his ammunition while he is on the balcony and make him attack you with his knife (a simple punch to the head is sufficient to get him to draw his knife). The Ranger Sequoia is now in his inventory and can be pick pocketed once Hanlon moves downstairs to his office. (PC) The Ranger Sequoia seems to be impossible to pickpocket from outside on the balcony after removing Hanlon's ammo, wait until Hanlon relocates to his office and then attempt to pickpocket him prior to speaking to him.
 * You can combine both of the above methods to acquire two copies of the weapon and recover double the amount of .45-70 Gov't ammo. Steal his ammo on the balcony, get him to attack you with his knife, put away your weapon so he returns to non-aggressive and then speak to him about his actions. Once he moves downstairs to his office, pickpocket his gun and then finish the dialogue options to turn him in. After he commits suicide you can loot the ammo, a combat knife and a Ranger Vest outfit from his corpse and the Ranger Sequoia will be on the floor at his feet.
 * Also occasionally found on Veteran Rangers. A Veteran ranger can be killed with a silenced weapon from the hidden position with no karma loss or reputation loss, resulting in a consequence free unlimited supply of these weapons.
