Arca rail is the way to go!
Not only for bipod use, you an clamp into a tripod, plate or bag attachment.
I really like the area 419 stuff, it’s very well made, excellent fit and finish, come in a variety of configurations and have something specific to area 419 called arcaloc. It’s a tooth like locking system that’s rock solid and also compatible with all standard arca Swiss clamps.
Check em out. You’ll be very happy you did.
