Blackhawk Swivel Stud Picatinny Rail Adapter. Lightly used. You would use this to convert a swivel stud to a picatinny rail in order to mount a bipod or another accessory. This is good if you don't want to drill into your stock for a permanent picatinny rail. I don't believe this product is made anymore, but not certain. Please let me know if you have any questions.
$25 shipped to lower 48. PP FF or Venmo.
