Suppressing AR

Hey everyone,

Thinking about throwing an Otter Creek Labs Polonium Suppressor on my blem Palmetto PA-15. It’s got a 16 inch barrel and it feels a bit overgassed.
I know this rifle is a budget option so I’m not sure if a suppressor would hinder performance at all. Is this a good idea and would it be necessary to add an AGB or change the buffer spring?

Thanks guys
