How to Unlock A.R.C. M1 Underbarrel in BO7
Call of Duty: Black Ops 7 (BO7) introduces a wide range of weapon attachments designed to enhance gameplay versatility, and the A.R.C. M1 Assault Frame underbarrel attachment stands out as a game-changer for players who favor aggressive playstyles. This top-mounted control system transforms the A.R.C. M1 launcher, shortening charge and cooldown times, boosting the explosion radius, and improving mobility and handling-making it a valuable addition to any loadout.

Unlocking the A.R.C. M1 Assault Frame is not a random drop or a simple level-up reward; it requires completing specific in-game challenges tied to Black Ops 7's Season 2 content. Whether you're a casual player or a competitive grinders, understanding the unlock requirements and strategies will help you add this powerful attachment to your arsenal efficiently.
1. Understand the Basics: What Is the A.R.C. M1 Assault Frame?
Before diving into the unlock process, it's important to know what the A.R.C. M1 Assault Frame does and why it's worth pursuing. Unlike standard underbarrel grips that focus on recoil control, this attachment is exclusive to the A.R.C. M1 launcher-a manually aimed, four-shot burst weapon unlocked at Player Level 25.
The Assault Frame addresses one of the A.R.C. M1's biggest drawbacks: its slow charge and cooldown times. By equipping this underbarrel attachment, players can use the launcher more aggressively against enemy personnel, while also benefiting from a larger explosion radius and improved mobility-critical for staying competitive in fast-paced multiplayer matches.
Notably, the A.R.C. M1 itself is a versatile launcher, capable of destroying vehicles, scorestreaks, and enemy equipment. Unlike tracking launchers like the Arrow 109, it ignores countermeasures such as flares, making it even more valuable in scenarios where enemies rely on defensive tools.
2. Key Prerequisite: Unlock the A.R.C. M1 Launcher First
You cannot unlock the A.R.C. M1 Assault Frame underbarrel attachment without first unlocking the base A.R.C. M1 launcher. Fortunately, this prerequisite is straightforward: the A.R.C. M1 becomes available once you reach Player Level 25 in Black Ops 7.
Leveling up your player rank is relatively simple-focus on playing multiplayer matches, completing daily and weekly challenges, and earning scorestreaks. Even casual play, such as objective-based modes like Domination or Hardpoint, will help you grind XP efficiently.
Once you hit Level 25, the A.R.C. M1 will be added to your launcher inventory. You can then equip it in your loadout and start using it to familiarize yourself with its mechanics-this will be helpful when you begin working on the Assault Frame unlock challenge.
3. Unlock Requirement: Complete Season 2 Weekly Challenges
The A.R.C. M1 Assault Frame is a Season 2 exclusive attachment, and it can only be unlocked by completing weekly challenges during this season. Specifically, you need to finish any six weekly challenges that rotate throughout Season 2.
Weekly challenges in Black Ops 7 reset every Thursday at 9 AM PT, so it's important to check the challenge menu regularly to stay on track. These challenges vary in difficulty and type, but most are designed to be achievable with regular play-you won't need to grind for hours on end to complete them.
Examples of common weekly challenges include getting a certain number of kills with a specific weapon type, capturing objectives, destroying enemy scorestreaks, or completing matches in a particular game mode. Many of these challenges align with normal gameplay, so you can work on them naturally while playing your favorite modes.
4. Efficient Strategies to Complete Weekly Challenges Fast
To unlock the A.R.C. M1 Assault Frame quickly, focus on completing weekly challenges that align with your playstyle. If you prefer aggressive play, prioritize challenges that require kills or objective captures. If you're more of a support player, focus on challenges that involve destroying enemy equipment or assisting teammates.
Pairing the A.R.C. M1 with complementary weapons can also help. For example, using a fast-firing SMG like the Razor 9mm or Dravec 45 will compensate for the A.R.C. M1's slow charge time, allowing you to stay effective in close to mid-range fights while working on challenges.
Additionally, take advantage of double XP events. Black Ops 7 often runs double XP weekends or limited-time events that boost XP and challenge progress. These events are perfect for accelerating your weekly challenge completion and getting closer to unlocking the Assault Frame.
5. Equip and Optimize the A.R.C. M1 Assault Frame
Once you complete six weekly challenges, the A.R.C. M1 Assault Frame will be unlocked and available in the Gunsmith menu. Before equipping it, ensure you have Custom Loadouts unlocked-this feature becomes available at Progression Level 4, allowing you to access the Gunsmith and modify your weapons.
To equip the Assault Frame: Navigate to your Custom Loadout, select the A.R.C. M1 launcher, open the Gunsmith menu, and find the Underbarrel category. The A.R.C. M1 Assault Frame will be listed there, and you can equip it with a single click.
To maximize the attachment's effectiveness, pair it with other A.R.C. M1 accessories. For example, the MFS Fast-Action Trigger (a peak attachment for the A.R.C. M1) eliminates shooting delay and increases fire rate, complementing the Assault Frame's speed boosts-just note that it will reduce recoil control and effective range.
6. Common Mistakes to Avoid
One common mistake players make is ignoring the A.R.C. M1 itself before unlocking the Assault Frame. Familiarizing yourself with the launcher's mechanics-such as its charge time and projectile travel-will make it easier to use once the attachment is equipped, and it may even help you complete weekly challenges faster.
Another mistake is missing weekly challenges. Since challenges rotate every week, failing to complete even one can delay your unlock. Set a reminder to check the challenge menu each Thursday and prioritize completing at least one challenge per day to stay on track.
Finally, don't overlook the A.R.C. M1's camo challenges. While not required to unlock the Assault Frame, completing camo challenges (such as destroying scorestreaks or getting kills while moving) can help you practice using the launcher and earn cosmetic rewards at the same time.
