Yes you can.
The difference is the SiCo pistons have grooves for clocking the Ospreys. There is an argument these grooves add to the blowback.
I only use Rugged pistons so I can't confirm these assertions.

Will second that. SiCo pistons work in the Obsidian.

It doesn't matter. They are literally the exact same piston, minus the slots in the SiCo one for timing the Osprey.
Henry Graham, one of the founders of Rugged, who designed the Obsidian, is also a former employee of SiCo, and worked on their products while he was there. He has said that it's fine to interchange the pistons.
