If you’re trying to craft mid-tier weapons like the Renegade, Tempest, or Torrente in ARC Raiders, you already know the bottleneck: Medium Gun Parts.
The catch? It doesn't have a single, fixed spawn point where it sits waiting for you. It relies heavily on RNG (random number generation) and spawns as a high-tier loot drop.
Here is a breakdown of how the numbers stack up and exactly where you need to focus your farming runs.
📦 The Containers with the Highest Drop ProbabilityIf you want to optimize your time, stop opening every plastic bin or random trash pile. Community data suggests targeting specific containers heavily associated with high-value military and residential loot.
Raider Caches: These are widely considered the gold standard for blueprint hunting. They emit a distinct "tick-tick" acoustic sound that grows louder as you approach.
Focus on caches found on the outskirts of maps—players running perimeter-only cache loops report finding multiple blueprints over extended sessions.
Weapon Cases & Gun Crates: These are dark green military boxes found inside high-threat zones (marked red or yellow on your overlay) or behind locked doors requiring specific keycards.
Residential Drawers & Desks: Don’t ignore office chairs and filing cabinets. When exploring multi-story residential areas, checking every single desk drawer can yield blueprints that other players pass up.
According to tracking data compiled by community databases like MetaForge, the drop distribution for the Medium Gun Parts Blueprint across Calabretta isn't uniform. Player drop logs reveal the following map success rates:
Dam Battlegrounds:~40% of logged community drops
The Blue Gate: ~18% of logged community drops
Stella Montis:~18% of logged community drops
Buried City:~14% of logged community drops
The Spaceport:~8% of logged community drops
With a roughly 40% community success rate, the Dam is your best bet.
The Apartments: Check the residential complexes on the northern side. Loot every kitchen cabinet, desk drawer, and locker.
Control Tower & Water Treatment: Grab a Dam Surveillance Key or a standard security keycard. The locked rooms inside these facilities guarantee high-tier weapon crates.
Water Towers:Bring a couple of ziplines or a snap hook.
Though it sits at a 14% drop rate, the Buried City offers an incredibly fast and safe farm loop on its eastern edge.
The East Bridge:On the far-right side of the map near a common spawn zone, there are three distinct spawn points underneath the massive bridge structure.
Raider caches appear here regularly. Multiple players on Reddit have confirmed pulling their white or blue-tier Medium Gun Parts Blueprint directly from these under-bridge caches.
While it has a lower overall baseline drop rate, the Spaceport becomes highly lucrative under the right conditions.
Departure Building: Search the exam rooms, metal cabinets, and desk drawers.
Launch Tower Tunnels:Drop into the subterranean tunnels directly underneath the main tower to check the green weapon cases.
If your luck with RNG is hitting a wall, you can tilt the odds in your favor using a few tactical adjustments:
Run Night Raids or High-Modifier Matches: Loot tables scale up in difficulty and quality during night raids. Running Spaceport or Buried City at night noticeably bumps up the appearance of high-tier blueprint drops in standard containers.
Farm During "Exposed Caches" or "Cold Snap" Events: Map modifiers like Raider Cache Events flood the perimeter zones with active caches, letting you check 10 to 15 boxes per match rather than the usual 3 or 4.
Third-Party and Peer Trading: If you have run 50 matches and still haven't found what you need, you don't necessarily have to rely on the standard Metaforge marketplace. Some players look into external trading communities like U4N to check for standard peer-to-peer weapon part packs or explore listings for arc raiders ps5 blueprints for sale to bypass the grinding altogether.
If you don't have the blueprint yet but need to keep your squad armed, you can use two stopgap methods to source individual parts:

You can trade 15 seeds per part, up to a maximum of 3 Medium Gun Parts every 24 hours.
