ARCA is a quick dovetail system for mounting bipods and other attachments.  The ARCA swiss attachment system started out in the photo/video world as a secure attachment method between cameras and tripods.  This is a strong system that is easy to use.  You attach the ARCA rail plate to your MLok slots on your rifle, and your Arca compatible bipod slides on and locks in.  Attachment/removal is super fast and secure.  If you’re looking for a stable, easy to use mounting system, definitely check these out.
