To level up weapons fastest in MW4 Season 1, one must play objective-based Multiplayer, use Double Weapon XP tokens, and equip shared attachments to skip weapon levels. Switching guns randomly slows progress. That’s especially true when unlocking attachments across multiple classes.
A smarter approach starts with a single weapon and builds from there. Check out our Best MW4 Season 1 Loadouts for a strong starting build, and consult Activision’s MW4 Progression and Prestige Guide for official progression details.
Here’s how to make every match count.
How Does Weapon XP Work in MW4?
MW4 tracks Weapon XP and Player XP separately. Player rank unlocks equipment, weapons, perks, and other options. Meanwhile, Weapon XP unlocks individual guns and their attachments.
Activision also introduced a shared attachment system to make weapon progression less repetitive. Once unlocked, an attachment is available for every compatible weapon. You won’t need to grind for it again. That’s a big deal when you’re working through an entire weapon class.
Here’s what you should understand before starting:
| Progression Type | Description & Operational Benefits |
| Weapon XP | Progresses an individual weapon’s level and unlocks its available attachments. |
| Player XP | Advances your overall Multiplayer rank and unlocks account-level rewards. |
| Shared Attachments | Makes previously unlocked attachments available across compatible weapons. |
| Bonus Level Ups | Skips weapon levels that would otherwise award attachments you’ve already unlocked. |
| Weapon Prestige | Becomes available after reaching a weapon’s maximum level and offers an additional progression track. |
You can earn Weapon XP through both Multiplayer and DMZ, so you’re not restricted to traditional PvP matches. You can use Double Weapon XP tokens throughout the leveling process to speed things up.
However, the real advantage comes from planning your weapon progression. Leveling one gun can make the next compatible weapon easier to upgrade, so don’t spread your progress across your entire arsenal without a plan.

Best Game Modes for Weapon XP in MW4 Season 1
Hardpoint, Kill Confirmed, and Domination are strong choices for weapon leveling because they reward both objective participation and eliminations. Small-map playlists can also help you find more fights without spending half the match running across the map.
Here’s how the main options compare:
| Game Mode | Strategic Value & Match Dynamics |
| Hardpoint | Concentrates fights around rotating objectives and rewards players who help hold the hill. |
| Kill Confirmed | Rewards scoring eliminations and aggressively collecting dropped enemy tags. |
| Domination | Encourages repeated fights around capture points and contested flags. |
Hardpoint: Consistent Objective-Based XP
Hardpoint is an excellent starting point if you want to maintain consistent action throughout a match. Players naturally converge on the active hill, giving you plenty of opportunities to secure eliminations while contributing to the objective.
Never spend the entire match chasing kills outside the objective area. Stay close to the hill, defend it, and use your weapon whenever fights break out.
Kill Confirmed: Turn Every Elimination Into Progress
Kill Confirmed rewards aggressive players who collect tags rather than leaving them scattered across the map. Each elimination offers an opportunity to earn additional objective-related score by picking up the dropped tags.
Play aggressively, but don’t ignore the objective. Collecting tags is part of the job.
Domination and Grind: Keep the Pressure on Objectives
Domination works well because players repeatedly fight over three capture points. Holding and capturing flags keeps you involved in the action and gives you reasons to engage opponents around predictable locations.
Grind offers another objective-focused option. Collect Dog Tags and bank them rather than treating every encounter like a standard Team Deathmatch. Your objective participation matters.
How to Use Double Weapon XP Tokens Efficiently
Double Weapon XP tokens can shorten the time needed to unlock attachments and reach a weapon’s maximum level. The trick is to activate them when you’re ready to play several matches without interruptions.
Don’t waste a limited-duration token while you’re adjusting loadouts or sitting in menus.
Activate the Correct Double XP Token
MW4 separates Player XP and Weapon XP bonuses, so activate a Double Weapon XP token rather than a regular Double XP token. This distinction matters. You want your equipped gun to receive the bonus progression, not just your overall account rank.
- Before activating one:
- Equip the weapon you want to level.
- Choose your preferred XP-farming playlist.
- Adjust your attachments and class setup.
- Ensure you have enough time for an uninterrupted session.
Save Tokens for Longer Grinding Sessions
Don’t activate a token just because you have one available. Wait until you’re ready to play several consecutive matches, preferably in a playlist where you can consistently secure eliminations and contribute to objectives.
Small-map playlists and Hardpoint are good starting points. You’ll spend less time searching for opponents and more time using your weapon.

MW4 Shared Attachments and Bonus Level Ups Explained
Shared attachments are one of the biggest shortcuts in MW4’s weapon progression system. Instead of repeatedly unlocking the same compatible attachment, you can use an attachment you’ve already unlocked on another supported weapon.
Bonus Level Ups make this even more useful by skipping levels for attachments you’ve already unlocked.
How Shared Attachments Work
MW4 allows compatible weapons across multiple classes to share universal attachments (such as optics, muzzles, and underbarrels). Once unlocked, these attachments are instantly available on any weapon that supports the slot, regardless of class.
Specialized weapon modifications, such as gun-specific Apex Attachments, remain unique to their respective firearms. This gives you a reason to focus on one weapon before moving to another. Every compatible attachment you unlock can reduce the effort required when switching guns.
However, shared attachments don’t mean every weapon automatically gets every attachment. Compatibility still matters, so check the Gunsmith before planning your progression route.
What Are Bonus Level Ups?
Bonus Level Ups reward your previous progression by granting bonus Weapon XP when advancing a new gun. If a weapon level milestone would normally reward an attachment you have already unlocked on a previous gun, MW4 awards a Bonus Level Up instead, accelerating your progress to the next level.
This makes your first weapon especially important. The more useful shared attachments you unlock, the greater the progression benefits you can carry over to compatible weapons.
The Best Weapon Leveling Order
Don’t level your weapons randomly. Follow this approach instead:
| Step | Operational Strategy & Progression Workflow |
| 1. Choose Your Main Weapon | Start with an assault rifle, SMG, or another weapon class you use frequently. |
| 2. Unlock Shared Attachments | Progress far enough to collect useful attachments that other weapons in the same class can support. |
| 3. Switch to a Compatible Weapon | Check which attachments are already available before investing time leveling another gun. |
| 4. Take Advantage of Bonus Level Ups | Let previously unlocked attachments reduce the number of levels you need to complete. |
| 5. Repeat with Other Weapon Classes | Build your attachment collection gradually instead of jumping randomly between unrelated guns. |
The smartest move is to prioritize the weapons you actually want to use. There’s little point in spending hours unlocking attachments for guns that will sit unused in your loadout.
The Fastest Way to Max Out Weapons in MW4
The most efficient weapon-leveling strategy combines a focused loadout, objective-based matches, Double Weapon XP tokens, and shared attachment progression. Instead of grinding each gun separately, work through compatible weapons in a planned order to maximize each match.
Step 1: Choose Your Target Weapon
Pick one weapon to max out and stick with it until you’ve unlocked a useful selection of attachments. Constantly switching between guns splits your progress and makes it harder to build a shared attachment collection.
Start with a weapon that suits your preferred playstyle. Assault rifles and SMGs are good starting points if you regularly play standard Multiplayer modes.
Step 2: Build an Effective Loadout
Your loadout should help you win fights consistently. Don’t equip attachments just because they look impressive; prioritize those that improve handling, accuracy, recoil control, or mobility.
Choose attachments that suit the map and game mode you’re playing. A close-range setup might work well on Shipment but feel awkward on a larger map.
Step 3: Combine XP Methods
Once your loadout is ready, focus on earning as much Weapon XP as possible in each session.
- Activate a Double Weapon XP token before starting your grind.
- Queue into Hardpoint or Kill Confirmed.
- Prioritize eliminations and objective participation.
- Choose compact maps for more frequent engagements.
- Keep your target weapon equipped throughout the session.
Consistency beats constantly changing strategies. Find a playlist where you perform well, then stick with it.
Step 4: Move to Compatible Weapons
After unlocking a useful attachment collection, switch to another compatible weapon to see which options are already available. Bonus Level Ups can reduce the progression required, making subsequent weapons less time-consuming to develop.
Repeat this process across your preferred weapon classes. You’ll spend less time relocking attachments and more time working toward your remaining weapon levels.
Common Weapon Leveling Mistakes to Avoid
Even with the right XP strategy, a few bad habits can unnecessarily slow weapon progression. Watch out for these mistakes:
| Common Pitfall | Strategic Correction & Operational Avoidance |
| Switching Weapons Too Often | Focus on one gun long enough to unlock useful shared attachments. |
| Wasting Double Weapon XP Tokens | Activate them when you’re ready for a proper, uninterrupted grinding session. |
| Ignoring Objectives | Don’t chase kills while leaving easy objective-related score behind. |
| Using Unsuitable Attachments | A poorly configured weapon can make winning gunfights significantly harder. |
| Overlooking Bonus Level Ups | Check your shared attachments before starting another weapon. |
| Trusting Unverified XP Glitches | Many exploit videos circulate without reliable proof, and methods frequently break after patches. |
You don’t need complicated tricks to make progress. A focused weapon rotation and consistent matches offer a more reliable approach.
Is There a Weapon XP Glitch in MW4 Season 1?
There isn’t a verified weapon XP glitch you should rely on for consistent progression. Most players will get better results from objective-based Multiplayer matches, Double Weapon XP tokens, and Bonus Level Ups than from chasing questionable exploit videos.
Searches for the MW4 weapon XP glitch often lead to videos claiming players can max out weapons in just a few matches. Be cautious about those claims. Game updates can patch exploits, and an unverified method might waste more time than it saves.
Stick to legitimate XP methods. If a new exploit appears, check whether reliable sources or official patch notes confirm it before trying it out.

Frequently Asked Questions (FAQ)
What is the fastest way to level up weapons in MW4 Season 1?
Focus on one weapon, play objective-based modes, and activate Double Weapon XP tokens during longer sessions. Prioritize weapons that share useful attachments.
Does MW4 have shared attachments across all weapons?
No. Attachments are shared only among compatible weapons, not every gun in the game. Check the Gunsmith to see which weapons support each attachment.
Can you level up weapons in DMZ?
Yes. MW4 supports weapon progression in both Multiplayer and DMZ, so you can earn Weapon XP without exclusively playing traditional PvP matches.
What happens when you reach a weapon’s max level?
Reaching a weapon’s maximum level unlocks its unique Apex Attachment and lets you enter Weapon Prestige. Entering Weapon Prestige resets the weapon’s level to 1 and relocks its standard attachments. Your unlocked Apex Attachment remains permanently available throughout the Prestige track.
