All sentinels do not attack by default unless they possess an attacking precept such as Assault Mode.
However, the only way to get another sentinel's weapon is to craft that particular sentinel to retrieve their specific weapon. Sentinels can equip other Sentinels' weapons (with the exception of Helios's Deconstructor, which can only be equipped on Helios, though Helios can freely use other weapons) provided additional weapons are available.
The components and blueprints for Carrier Prime, Dethcube Prime, Helios Prime and Wyrm Prime are obtained through Void Relics, their respective Prime Access packages, or through Trading between other players. It can be traded, but only for unranked copies without Forma or Orokin Reactor installed. Note that Baro Ki'Teer's stock changes with each appearance, and this weapon may not be available on a succeeding appearance. A built Prisma Shade can be purchased from Baro Ki'Teer for 300,000 Credits 300,000 and 500 Ducats 500. The blueprint for Oxylus can be traded for Solaris United Standing at The Business on Fortuna, Venus. The blueprints for Djinn and Helios can be researched from the Bio Lab and Energy Lab in the dojo. The blueprints for Carrier, Dethcube, Diriga, Shade, and Wyrm can be purchased from the Market for 100,000 Credits 100,000. Additional blueprints can be purchased from the Market for 5,000 Credits 5,000. The blueprint for Taxon is awarded for completing the Earth to Venus Junction.
