I have that rail and nut in my junk parts box. I thought it may have came from a bipod

It's part of that two piece sling swivel stud to picatinny rail mount adapter. They do come with bipeds.

Nope.
PM me your address and I'll just mail it to you. Im sure if it came with a bipod, it left here a good while ago. I just hoard crap
