Accuracy international chassis rail selection

[Porter24]

I picked up a pretty cool rifle, Borden 6br in an AI chassis, always loved these growing up. The guy I got it from rigged up a pic rail and it needs upgraded. I’m having a hell of a time figuring out what to get, a standard key mod pic rail didn’t fit.

Can anyone post some options and the correct one to order, going to either go pic rail 3-4in or go with an arca rail.

Thanks in advance

It’s keyslot (AI proprietary), not keymod, which is why you’re having issues. Any pic rail marked keyslot would work, provided the length is right, of course.

Mile High probably has keyslot pic rail sections. For arca along the bottom, you can look at Sawtooth Rifles. Keep in mind you have a pre 14 chassis in case you want to replace the grip area with arca.
