We will farm the desired amount of Nightfalls: The Ordeal at Grand Master Level, in order to obtain Buzzard (Adept) - Sidearm. Nightfall: The Ordeal Adept Weapons are not guaranteed on completion, this is why we offer flexible ETAs and prices.
NOTE: From Season of the Lost, 2 Nightfall: The Ordeal  Adept weapons are available per week. This could delay the order completion since we could have to wait until your desired weapon is available.
