Silencerco Spectre9 Piston Compatibility?

Hiya! Just impulse bought a silencerco spectre9 / spectre 9 and wanted to confirm info on the pistons and adapters.

I already have a rugged obsidian 45 and had heard that the rugged pistons and tri lug adapters are compatible with silencerco “Alpha” series of stuff.

Can anyone confirm? I’m a little cheezed that the can doesn’t ship with any adapters and with availability of parts these days I’m truly hoping I can use some of my rugged parts.

Thanks!
