Does upgrading a gun keep the same secondary stats, or does it change it?

Comment by blaket77

Nothing about the item upgrades says BoP, so that means I can make a gun and item upgrade(s) and send them to my hunter and have an upgraded gun even though my hunter is not an engineer. Am I understanding that correctly?

This upgrades Engineer BoE gun from ilvl 630 to ilvl645

Comment by Tygerlilly

Ridiculous requirements. 150 Gearspring Parts + 30 Sorcerous Fire + 15 Savage Blood.

Savage Blood going for 2k a pop on my server. Alternative is to grind for 750 Primal Spirits - which I would have had I not purchased a bunch of Gearspring Parts to make the ilvl 630 gun in time for our first raid. If you want to raise it to 655, you'll need 200 more Gearspring Parts + 30 Sorcerous Air + 15 Savage Blood.

Not gonna happen. I think I'll make a Blingtron 5000 instead.

If you came here like I did trying to find the next upgrade after Unstable True Iron Trigger then this post might help you.

What you are looking for is this:

2nd gun upgrade is: Schematic: Blackrock Rifling which creates Unstable Blackrock Rifling

Good luck hunting !

This now updates to 645, not 640.

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

*UPDATE for June 23, 2015* - Unstable Blackrock Rifling and Unstable Precision Scope Tuning Kit 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:
Unstable True Iron Trigger	True Iron Trigger + 15 X Sorcerous Fire
Unstable Blackrock Rifling	True Iron Trigger + 25 X Sorcerous Air
Unstable Precision Scope Tuning Kit	True Iron Trigger + 25 X Sorcerous Earth

As of 6.2, the new initial upgrade item will be True Iron Trigger (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) - True Iron Trigger
Stage 2 to 3 (Item level 645 to 660) - True Iron Trigger
Stage 3 to 4 (Item level 660 to 675) - True Iron Trigger
Stage 4 to 5 (Item level 675 to 690) - Advanced Muzzlesprocket
Stage 5 to 6 (Item level 690 to 705) - Taladite Firing Pin

**Note that 3 separate True Iron Trigger 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 Savage Blood 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 "Appraiser" Sazsel Stickyfingers (H)/Ashley Zerep (A) in your garrison for 25 Primal Spirit each
The Felblight used for upgrades to Stage 5 and 6 are obtained from mining, herb gathering, skinning, or fishing in Tanaan Jungle

Materials

Schematic

True Iron Trigger	70 X Gearspring Parts 15 X Sorcerous Fire 15 X Savage Blood	Schematic: True Iron Trigger, sold in: - Warspear (Nik Steelrings) - Stormshield (Sean Catchpole) - Vendor in Garrison Engineering Works building Cost: 5 Secret of Draenor Engineering
Advanced Muzzlesprocket	175 X Gearspring Parts 30 X Sorcerous Earth 30 X Felblight	Schematic: Advanced Muzzlesprocket, sold by the Ore Trader visitor in your garrison - Alexi Hackercam (A) or Trixxy Volt (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 True Iron Ore
Taladite Firing Pin	350 X Gearspring Parts 60 X Sorcerous Earth 60 X Felblight	Schematic: Taladite Firing Pin, sold by the Ore Trader visitor in your garrison - Alexi Hackercam (A) or Trixxy Volt (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 True Iron Ore

This brings the total cost of upgrading the gun (from Stage 1 to 6) to:
735 X Gearspring Parts (Not including 100 X Gearspring Parts to craft the gun)
45 X Sorcerous Fire
90 X Sorcerous Earth
90 X Felblight
45 X Savage Blood

Notes about the Engineering guns (Shrediron's Shredder):

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 Gearspring Parts 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 Didi's Delicate Assembly (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

A chart of the possible random secondary enchants for this item follows below, with the two stat combinations for each enchant (the gun would be named "Shrediron's Shredder of the Random Enchantment", where the Random Enchantment is one of the below names):

STAT	Critical Strike	Haste	Mastery	Versatility	Multistrike
Critical Strike	X	Fireflash	Peerless	Quickblade	Savage
Haste	Fireflash	X	Feverflare	Aurora	Deft
Mastery	Peerless	Feverflare	X	Harmonious	Merciless
Versatility	Quickblade	Aurora	Harmonious	X	Strategist
Multistrike	Savage	Deft	Merciless	Strategist	X
