COD Black Ops 7 Apr-21-2026 PST

Call of Duty: Black Ops 7 Season 3 has introduced a range of new weapons to enhance your multiplayer and Warzone experience, and the MK35 ISR assault rifle stands out as a fan-favorite from the start. Inspired by the beloved M27 from Black Ops 2, this full-auto AR boasts low recoil, solid accuracy, and a clean iron sight, making it a versatile choice for medium-to-long range gunfights. Whether you're a casual player or a competitive gamer, unlocking the MK35 ISR is straightforward-if you know the right steps. This guide breaks down all methods to get your hands on this powerful weapon, plus tips to speed up the process and maximize its potential.

How to Unlock MK35 ISR in Black Ops 7

What You Need to Know About the MK35 ISR First

Before diving into unlock methods, understanding the MK35 ISR's strengths will motivate you to add it to your loadout. Unlike other assault rifles in its class, it offers the lowest recoil while maintaining a fast fire rate, making it easy to stay on target even during sustained fire. It has moderate damage and handling, so positioning and accuracy will be key to mastering it.

The MK35 ISR also features a prestige attachment: the 19" MFS Nightfall Suppressed Barrel. This integrated suppressor keeps you off the enemy radar while firing, extends your effective damage range, and tightens hip-fire spread-perfect for stealthy playstyles. With 43 weapon levels and a variety of attachments, it's a weapon that rewards progression and customization.


Main Method: Unlock via the Season 3 Battle Pass (Free Tier)

The primary way to unlock the MK35 ISR is through the free tiers of Black Ops 7's Season 3 Battle Pass. Activision has made this weapon accessible to all players, regardless of whether they purchase the premium pass or not. It is listed as a High-Value Target (HVT) reward on Page 3 of the Battle Pass.

To unlock it, you first need to progress through the preceding pages of the Battle Pass. This means earning Battle Pass (BP) tokens by playing the game, completing challenges, and gaining XP. Once you reach Page 3, you'll need to claim the standard rewards on that page using your BP tokens before unlocking the MK35 ISR as the HVT reward.

The good news is that you don't need to spend real money for this method. It's entirely free, but it requires time and consistent play. Even casual players can unlock it within a few days of Season 3's launch if they focus on earning XP efficiently.


Fast Track: BlackCell Battle Pass Shortcut

If you want to unlock the MK35 ISR instantly, purchasing the BlackCell Battle Pass upgrade is the way to go. BlackCell is the premium tier of the Season 3 Battle Pass, offering exclusive content and instant access to key rewards.

With BlackCell, you can skip straight to Page 3 of the Battle Pass, unlocking the MK35 ISR immediately without grinding for BP tokens. Additionally, BlackCell users can access Page 12, where the "Saku" weapon blueprint for the MK35 ISR is available-giving you a head start with preset attachments.

BlackCell also includes other perks, such as the Valkyrie operator skin, 1,100 COD Points, and exclusive camo challenge tracks. While it requires a purchase, it's ideal for players who want to jump into using the MK35 ISR right away.


Alternative: Store Bundles (Possible Option)

Activision often releases store bundles featuring new weapons, and the MK35 ISR is likely to be included in one of these bundles at Season 3's launch. Purchasing such a bundle will grant you instant access to the base MK35 ISR, along with a unique blueprint.

Keep in mind that blueprints come with preset attachments, but you'll still need to level up the MK35 ISR itself to unlock all available attachments. This method is convenient for players who don't want to grind the Battle Pass or purchase BlackCell, but it may cost real money depending on the bundle.


Tips to Speed Up Unlock Progression

If you're unlocking the MK35 ISR via the free Battle Pass, these tips will help you earn XP and BP tokens faster. First, focus on completing daily and weekly challenges-they offer generous XP rewards and are often easy to finish in a few matches.

Objective-based game modes are also your friend. In Black Ops 7 multiplayer, modes like Hardpoint and Domination reward you for capturing and holding points, which grants more XP than just getting kills. In Warzone, completing contracts (such as Bounty or Secure Intel) is a quick way to earn XP and BP tokens.

Additionally, use XP boosters if you have them. These can be earned through challenges or purchased in the store, and they double your XP gain for a set period. Pairing an XP booster with objective-based play will cut your grind time in half.


What to Do After Unlocking the MK35 ISR

Once you have the MK35 ISR, take time to level it up to unlock its full potential. Reach max weapon level (Level 43) to access all attachments, including the prestige 19" MFS Nightfall Suppressed Barrel. Experiment with attachments to tailor it to your playstyle-opt for a scope for long-range fights or a laser for improved hip-fire accuracy in close quarters.

You can also work toward unlocking camos for the MK35 ISR. From military camos (earned through headshots and critical kills) to mastery camos like Shattered Gold and Arclight, there are plenty of customization options to show off your skill.


Final Notes

The MK35 ISR is a versatile and powerful assault rifle that's worth adding to your loadout in Black Ops 7. Whether you choose the free Battle Pass method, the BlackCell shortcut, or a store bundle, unlocking it is simple and accessible. Alternatively, utilize MMOexp's Black Ops 7 Boosting or BO7 Bot Lobbies services to quickly unlock content.

Remember, if you miss the initial unlock window via the Battle Pass, the MK35 ISR will eventually be added to the Armory section of the menu. You'll then be able to complete a separate challenge to earn it, so you won't miss out on this fan-favorite weapon forever. With a little time and effort, you'll be dominating the battlefield with the MK35 ISR in no time.
