I have a few of these updated arca/Pic rails from SRS. Is the middle hole a Spartan bipod mount or just a qd sling mount? The mount on the Trinity rail for Spartan seems to stick much farther out? I don't have anything Spartan but just curious.
I don’t have one of those, but I have a couple spartan adapters. I don’t see how it could be a spartan adapter without metal at the bottom for the magnet to stick to.
