How MW3’s Gunsmith Aftermarket Parts will shake up multiplayer matches

Weapon customization in this year's game is unlike anything we have seen before thanks to Aftermarket Parts which add a whole new level of depth to each gun.

The Gunsmith has radically reformed Call of Duty’s weapon customization many times. From originally just allowing you to change your skin, camo, and add some stickers a decade ago to the modern era of the franchise where it allows you to fully customize half a dozen different attachment slots for each weapon.

With the Call of Duty MW3 Aftermarket Parts, you can now have entire weapon variants, which is a huge shakeup. As such it means the selection of Call of Duty MW3 guns is even more varied than we were expecting for the multiplayer portion of the game, which is sure to be one of the best FPS games when it releases.

The new Aftermarket Parts for the Gunsmith in Call of Duty MW3 add a deeper level of customization to every weapon as when equipped they alter the stats of your gun, radically changing the weapon’s performance or its strengths. For example, you can equip an Aftermarket Part to the semi-automatic Renetti Pistol to turn it into a full-auto carbine.

This completely overhauls how everyone will customize their weapons in Call of Duty Modern Warfare 3 as you are no longer just looking at individual statistics like rate of fire, mobility, and recoil control. Now you have to consider what form you want your gun to take and how that will affect your overall loadout, which is a brand new dimension of the Gunsmith we haven’t seen before, expanding the playstyles in the game dramatically. For example, you could run two long-range assault rifles or SMGs without using Overkill or a similar perk that lets you use two primary weapons – as we can see pistols are able to be turned into long-range weapons.

This is a level of customization that goes beyond Call of Duty MW2, which just offered the Receiver platform. All this did was allow you to use other attachments from weapons in the same weapon family upon unlocking them. It didn’t radically change the playstyle of the weapon you were using.

The developers in the video below describe these new attachments in the Gunsmith as “remixes for guns” – what if scenarios if you will, such as “what if you could make an LMG lighter”, allowing you to run and gun with it on one of the smaller Call of Duty MW3 maps.

But, not all of them will be aimed at improving a specific stat. The developers also state in this video that they want some of them to be “oddballs, that players are completely caught off guard by”. One of those strange Aftermarket Part weapons is a dual-wield WSP Swarm with silencers which might be really good for close-quarters Call of Duty MW3 game modes.

These parts are some of the most interesting aspects of Call of Duty Modern Warfare 3 we have seen so far and harken back to Sledgehammer’s first Call of Duty game, Advanced Warfare. That game had Supply Drops which featured weapon variants that could dramatically change how a weapon performs.

So, it is nice to see them go back to their roots with Modern Warfare 3. It will also encourage players to use the new weapons in the game, considering all the Call of Duty MW2 weapons are transferable to MW3, alongside some transferrable camos.

The Aftermarket Parts we have seen so far are:

  • Full-Auto Carbine Conversion – Renetti (pistol)
  • WSP Akimbo Brace Stocks – WSP Swarm (SMG)
  • Bullpup Kit – Pulemyot 762 (LMG)


How is the Gunsmith similar in Call of Duty MW3 to MW2?

Overall, the Modern Warfare 3 Gunsmith is similar in every other way beyond the Aftermarket Parts. From what we have seen in the gameplay video earlier on in this article. Your standard set of attachments for a weapon has returned and you can equip five attachments at once.

Notably, the Receiver platform is not available on any of the MW3 weapons we see, which suggests that the cross-progression of attachments and the process of unlocking them won’t be available for the new weapons in this year’s game.

So, as you can see, another new layer of weapon customization is coming in Modern Warfare 3 and we think it is one of the most exciting yet. There is a lot of potential for Call of Duty MW3 loadouts in this year’s game thanks to these new parts and we think we will see some of the most varied matches in terms of weapon use yet in Call Of Duty MW3 multiplayer matches.
