Mod it, do not build around it. Sweeper Prime is the shotgun that comes free with Carrier Prime: a 10 percent crit, 5 percent status close range gun whose job is to tag and finish stragglers. Give it flat damage and Viral and let the sentinel’s precepts do the real work.
Comes with Carrier Prime and fires only when the sentinel’s attack precept is equipped; Carrier’s real value is Ammo Case and Looter, not this shotgun.
The Sweeper Prime is the signature weapon for the Carrier Prime Sentinel, serving as a direct upgrade to the standard Sweeper. This robotic shotgun accepts shotgun mods, allowing for familiar build customization.
Initially introduced in Update 16.11, the Sweeper Prime has seen several rebalances, most notably in Update 37. This update significantly boosted its base damage, status chance, and critical chance, making it a more viable companion weapon.
Dealing primarily Impact damage, the Sweeper Prime benefits from two innate Madurai polarities, which can help in fitting essential mods. Its automatic trigger ensures consistent fire, making it a reliable source of damage and status application for your sentinel.
How to get the Sweeper Prime
- Sweeper Prime comes with Carrier Prime: build the sentinel and the weapon arrives with it. Carrier Prime is vaulted: open relics you already own, buy them for Aya when Prime Resurgence lists it, or buy the sentinel parts for platinum.
- Systems: Lith N2, Lith S2, Lith S3, Neo A1, Neo V3 and 3 more (vaulted relics).
- Carapace: Lith S5, Lith V10, Neo A4, Neo S1, Axi N2 (vaulted relics).
- Blueprint: Lith V7, Meso P12, Meso V1, Meso V3, Meso V4 and 1 more (vaulted relics).
- Cerebrum: Lith C1, Meso C1, Meso C2, Meso C7, Meso N3 and 1 more (vaulted relics; the rare slot in Lith C1, Meso C1).
- Run the fissure tier that matches each relic, refine the rare part’s relic to Radiant, and pick the best of the four results with a squad.
- Build the sentinel parts, then Carrier Prime; the Sweeper Prime is in the sentinel’s blueprint, with its own slot and no extra crafting.
Check the Relic finder for live odds; the set price on this page is what the built Carrier Prime set trades for on warframe.market. The weapon itself is untradeable.

Sentinel weapons take no weapon arcanes. The sentinel itself takes companion arcanes, and the precepts on the sentinel matter more than this gun.
