arc raiders muzzle brake 2 blueprint

[MaSOnCOopER538]

In ARC Raiders, controlling weapon kick can easily mean the difference between a successful extraction and losing your entire hard-earned loadout. Among the early-to-mid-game weapon attachments, the Muzzle Brake II Blueprint is highly sought after by players who want a balanced, reliable bump to their gunplay accuracy.
Unlike hyper-specialized mods that only address one recoil direction or introduce massive handling penalties, the Muzzle Brake II provides a clean, flat 20% reduction to horizontal recoil and a 20% reduction to vertical recoil. Weighing only 0.5 kg and possessing a vendor value of 2,000 Coins, it fits comfortably into standard loadouts for weapons like the Tempest, Arpeggio, Kettle, Ferro, and Renegade, drastically narrowing your bullet bloom during sustained automatic fire. 
Where to Find the Blueprint
Finding the Muzzle Brake II Blueprint requires a solid understanding of target farming. While it is technically classified as an Uncommon tier blueprint, its drop rates are heavily tied to residential zones and specific map states.
Data compiled by community trackers highlights exactly where your chances are highest:

• Buried City Map: This is by far the most reliable zone, accounting for roughly 57% of documented Muzzle Brake II blueprint drops. Focus your efforts entirely on multi-floor structures and the Grandioso Apartments residential area. Loot every desk, suitcase, trash can, and household container you pass. 
  
• Blue Gate Map: Coming in second, Blue Gate holds a 21% drop probability. Squads should aggressively clear out the dedicated Residential Area. 
  
• Dam Battlegrounds & Stella Montis: Both environments offer a minor 7% drop rate. In the Dam Battlegrounds, focus strictly on the Pale Apartments. 
  

Map conditions also play a massive role in what ends up in your loot pool. Standard conditions like a Night Raid give you a solid 38% baseline chance to roll high-value attachment blueprints from standard residential chests. Similarly, a Cold Snap modifier maintains an efficient 31% rate. However, avoid maps stacked with high-tier events like Harvester or Hidden Bunker runs. These events intentionally skew the loot tables toward Legendary gear blueprints (like the Jupiter or Dolabra), effectively pushing the Muzzle Brake II completely out of the reward calculation. 
Farming these zones takes time, and bad RNG can leave you empty-handed after hours of clearing apartments. If you want to skip the repetitive container loops, you can check out online marketplaces like U4N, where you can safely buy arc raiders blueprint bundles to bypass the random drop grind entirely and get your hideout fully upgraded. 
How to Use and Craft the Blueprint
Once you successfully secure the blueprint in your backpack, your primary objective is to reach an extraction point alive. If you are eliminated before extracting, the blueprint drops with your corpse and is lost. 
After returning safely to your hideout in Speranza, follow these steps to unlock the modification permanently:

1. Open your character inventory while in the hideout.
   
2. Select the Muzzle Brake II Blueprint and click "Learn and Consume." This unlocks the recipe permanently across your account.
   
3. Head over to your Workshop and interact with the Gunsmith Bench (requires Gunsmith Level 2). 
   
4. To craft the physical attachment, you will need to spend 2 × Mechanical Components and 4 × Wires. 
   

With a total material value hover cost of roughly 840 Coins in raw scrap equivalents, it is incredibly cheap to mass-produce once learned. Slap it onto your favorite rifle or SMG, and you will notice a tighter, much more manageable recoil pattern in your next deployment.
