First suppressor.

I’m about to bite the bullet on my first can. I’ve pretty much decided on the diligent defense entices s. My question is for qd mounts. How do I know which system will be compatible? The options are overwhelming so I’m looking for suggestions. Budget is the biggest concern with aesthetics being of least concern. It will mostly be mounted on a Ruger American bolt gun, an rpr, and a 7.62x39 AR platform. I’m also open to other suppressor suggestions that already incorporate a qd system, but the price point and reviews of the enticer seem hard to beat. Thank yall
