In ARC Raiders, locking down your weapon recoil is the difference between extracting with a backpack full of legendary tier loot or waking up back in the Speranza hideout with nothing. If you are running high-kick weapons like the Stitcher, Arpeggio, or Bobcat, the Muzzle Brake III is arguably one of the most critical attachments you can craft. It slashes both vertical and horizontal recoil by a massive 25% (though it does penalize you with a 20% increased durability burn rate).
The real headache? The Muzzle Brake III blueprint doesn't sit neatly on a specific table waiting for you. It relies heavily on RNG scavenging tables. However, by breaking down community drop data and mapping out exact percentages, you can target your farm effectively instead of running blind.
?️ Target the Right Maps (By the Numbers)
When you pull up your deployment terminal, don't just pick a map at random. According to community-tracked drop data from databases like MetaForge, the Muzzle Brake III Blueprint has drastically different drop rates depending on the region you deploy into:
Dam Battlegrounds (44% of tracked drops): By far your highest statistical chance. Focus your runs here. Specifically, you want to hit the Pale Apartments and the dense residential housing blocks.
Blue Gate (22% of tracked drops): The runner-up. Your primary target here is the multi-story "Blue Building" and its surrounding living quarters.
Buried City (19% of tracked drops): A solid alternative. Spend your time looting the office drawers inside the Hospital, the abandoned apartment buildings, and the local drug store.
The Spaceport (15% of tracked drops): The lowest of the main four, but highly dense. Check the second floor of the Control Tower and the office desks scattered through the main terminal.
Note: Data shows a 0% drop rate in areas like Riven Tides, Stella Montis, and the Husk Graveyard, so avoid hard-farming these zones if this specific blueprint is your goal.
?️ Container Priorities: Look for the Right Loot Pools
Inside these maps, the blueprint is tied to container types that hold residential, office, and weapon components. Don't waste time opening industrial crates or chemical bins. Instead, prioritize these four container types:
Desk Containers & Office Furniture: This includes writing tables, office desks, and filing cabinets.
Residential Drawers & Wardrobes: Cabinets, dressers, and bedroom furniture inside apartment complexes.
Security & Raider Lockers: Weapon cases and locked security lockers.
Fridges: It sounds odd, but multiple players across Reddit and community forums have explicitly confirmed finding the Muzzle Brake III blueprint inside kitchen refrigerators within apartment zones.
⚡ Optimizing Your Run for Legendary Drops
Because a Tier 3 Legendary blueprint is rare, going into a standard daytime raid will result in low efficiency. To stack the deck in your favor:
Run Night Raids: Deploying after dark automatically shifts container loot tables to favor higher-rarity drops.
Watch for 2x Map Modifiers: Only dedicate your hardest, full-clear farming runs when a map is under a Major Map Condition—such as an electromagnetic storm or a global snap—which doubles loot quality multipliers.
Bring Breaching Tools: Rooms that require a tool or keycard to breach pull from significantly upgraded loot pools. A desk inside a locked security room has a much higher probability of rolling a Tier III blueprint than a desk out in an open hallway.
If the grind gets too brutal, or if you keep getting picked off by rival players right before you can extract with your hard-earned blueprints, there are external options. You can easily check out online trading platforms or look into a trusted U4N search to find a safe arc raiders RMT store blueprints vendor to buy the recipe or the attachment directly, saving you hours of frustrating RNG.
?️ Crafting Requirements
Once you finally secure the blueprint and successfully extract, you’ll need to head to your Hideout’s workshop. To craft the Muzzle Brake III, you will need to have Gunsmith Level III unlocked and assemble the following materials:
2x Mod Components
8x Wires
5,000 Coins (Base crafting/value cost)
Equipping it will immediately make full-auto sprays on your primary weapons much more manageable, giving you the accuracy needed to take down heavy ARCs like the Bastion or Queen without wasting half your magazine into the sky.
