У меня этот рецепт и Схема: звездочка Цепесмаза покупаются, но изучить их невозможно, пишет "Это заклинание вам недоступно", а сам изготавливаемый предмет по рецептам "серый".

Ответ ГМа на мой запрос: "Дело в том, что данные рецепты были деактивированы и их невозможно больше изучить, это не ошибка. Мы уже сообщали разработчикам об этом, они должны были внести изменения на этот счет в следующем обновлении игры. Вы можете вернуть рецепты торговцу, продать любому вендору или уничтожить".

Schematic for this gun upgrade can be purchased in your Engineering Works building inside your garrison. For Horde you want to speak with Pozzlow, for Alliance you will be speaking with Zaren Hoffle.

It can also be purchased in Ashran if you do not have the Engineering Works building placed in your garrison yet. For Horde you will be looking for Nik Steelrings in Warspear. Alliance will be looking for Sean Catchpole in Stormshield.

The schematic costs five Secrets of Draenor Engineering, which you can make with your engineering profession once per day.

This is one of the upgrade items for the iLevel 630 epic guns that engineers can make and use.

*UPDATE for June 23, 2015* - Нестабильный нарезной ствол Черной горы and Нестабильный комплект настройки прицела can no longer be crafted. Pre-patch 6.2 upgrade items (created before the patch) can be deconstructed to create the following:

Item	Deconstructs to:
Нестабильный спусковой крючок из истинного железа	Спусковой крючок из истинного железа + 15 X Волшебный огонь
Нестабильный нарезной ствол Черной горы	Спусковой крючок из истинного железа + 25 X Волшебный воздух
Нестабильный комплект настройки прицела	Спусковой крючок из истинного железа + 25 X Волшебная земля

As of 6.2, the new initial upgrade item will be Спусковой крючок из истинного железа (used for any and all upgrades until Stage 4). The upgrade items required for each stage are listed below:
Stage 1 to 2 (Item level 630 to 645) - Спусковой крючок из истинного железа
Stage 2 to 3 (Item level 645 to 660) - Спусковой крючок из истинного железа
Stage 3 to 4 (Item level 660 to 675) - Спусковой крючок из истинного железа
Stage 4 to 5 (Item level 675 to 690) - Усовершенствованный надульник
Stage 5 to 6 (Item level 690 to 705) - Таладитовый боек

**Note that 3 separate Спусковой крючок из истинного железа items are required to get from Stage 1 to Stage 4.**

Notes about the upgrade items:

The upgrade items themselves are BoE and can be traded or sold on the Auction House
They can be used by anyone (not just engineers)
Using an upgrade item on a gun will NOT bind it to you if it is not already bound to you
The upgrade item will NOT change the combination or proportion of stats on the item (e.g. if non-upgraded version has versatility and haste, the upgraded item will also have versatility and haste, just more of each stat)
These items can be used on gear that is already equipped
These upgrade items are exclusively crafted by Engineers - you cannot craft them as a non-Engineering, even with the Engineering works building in your garrison
The Дикая кровь used for upgrades to Stage 2, 3 and 4 are obtained from the Garrison Barn, crafted by alchemists as a daily cooldown, or purchased from "Оценщица" Липпи Липкоручка (H)/Эшли Зереп (A) in your garrison for 25 Первобытный дух each
The Гибельная Скверна used for upgrades to Stage 5 and 6 are obtained from mining, herb gathering, skinning, or fishing in Tanaan Jungle

Усовершенствованный надульник	175 X Части механизмов 30 X Волшебная земля 30 X Гибельная Скверна	Схема: усовершенствованный надульник, sold by the Ore Trader visitor in your garrison - Алекси Хакеркам (A) or Триккси Вольт (H). Note that you have a 1/5 chance of having a tradeskill vendor in your garrison every day, and there is a set rotation of tradeskill visitors from day to day (between herb, fur, leather, ore and dust). The easiest way to find this vendor is to use the Group Finder under Custom Premade Groups on the day that the Ore Trader is active. Cost: 60 Истинная железная руда
Таладитовый боек	350 X Части механизмов 60 X Волшебная земля 60 X Гибельная Скверна	Схема: таладитовый боек, sold by the Ore Trader visitor in your garrison - Алекси Хакеркам (A) or Триккси Вольт (H).

This brings the total cost of upgrading the gun (from Stage 1 to 6) to:
735 X Части механизмов (Not including 100 X Части механизмов to craft the gun)
45 X Волшебный огонь
90 X Волшебная земля
90 X Гибельная Скверна
45 X Дикая кровь

Notes about the Engineering guns (Крошшер Крошшерон):

They are BoE and can be sold on the Auction House or traded
They DO NOT require Engineering to use
They can be equipped at Level 91
The guns require 100 Части механизмов to craft
The gun will be crafted with +93-139 each of two random secondary stats (chosen out of Critical Strike, Haste, Mastery, Versatility or Multistrike)
The secondary stats can be re-rolled (randomly reselected) using the consumable item Сверхточная машина Диди (1 item required per re-roll)
The quantity of secondary stats when crafted is random as well (e.g. one item may have +133 crit and +104 haste, while another of the same type may have +130 crit and +110 haste)
The gun changes in appearance to be more elaborate as it is upgraded, with the addition of a scope, bayonet, and various golden scrollwork accents
The gun counts towards 1 of the 3 maximum Warlords of Draenor crafted items that you can have equipped at one time

No longer worth buying. Cannot be learned, as error message states: "This spell is not available to you".

The same for Schematic: Linkgrease Locksprocket
