GTA Online Service Carbine Locations Map: Where to Find Every Part

Unlocking the military-style Service Carbine in GTA Online gives players access to one of the most reliable assault rifles in Los Santos. Instead of spending money at Ammu-Nation, players can assemble this weapon for free by searching for hidden components. Finding all the necessary rifle parts requires exploring active crime scenes scattered across the map.
How Crime Scenes Work in GTA Online
Crime scene events spawn randomly throughout San Andreas during active free-roam sessions. To trigger these spawns, players must remain in a session for at least twenty minutes before the events begin appearing. Approaching an active site reveals a small blue dot marker on your radar indicating an item to collect.
Searching these locations rewards players with individual weapon components along with bonus cash and RP. Investigating the area will draw immediate police attention, resulting in an automatic three-star wanted level. It is best to collect the piece quickly and make a swift escape using a fast air vehicle.
Where to Find Service Carbine Weapon Parts
There are ten potential crime scene spawn locations distributed between Los Santos and Blaine County. Common urban locations include Elysian Island, Strawberry, Del Perro Beach, and both East and West Vinewood. Rural spawn points can be spotted near the Alamo Sea, Grapeseed, Paleto Bay, Banham Canyon, and the Ron Alternates Wind Farm.
To assemble the full rifle, you must collect five specific weapon components: the barrel, magazine, receiver, sights, and scope. Since the spawn locations appear randomly, visiting multiple sites or hopping sessions is often necessary. Utilizing an aerial vehicle like the Oppressor Mk II allows you to sweep all ten points efficiently.
Assembling and Customizing the Service Carbine
Once you gather all five unique weapon parts, the Service Carbine is automatically added to your inventory wheel. Assembling the complete set also provides a substantial financial payout alongside your earned RP rewards. If you prefer to bypass the scavenger hunt, the weapon can alternatively be purchased directly from Ammu-Nation.
After unlocking the rifle, players can visit any gun store or Agency Armory to install performance upgrades and custom finishes. Adding extended magazines and tactical grips significantly improves its effectiveness during combat. Upgrading your equipment ensures you stay fully prepared for high-stakes missions and competitive encounters.
