Acquisition

• Earn a Gunsmith Engram by ranking up with Banshee-44 (the Gunsmith) at the Tower, by handing in Gunsmith Materials and weapon telemetry. Engrams can drop foundry weapons such as this one.
• Not known to be craftable and not an Adept weapon; the sources checked list no sunset or reissue details, so treat its current availability as unconfirmed (it is a Year 1 weapon and older rolls may be retired from the loot pool).
