Installing a stock on the adapter

  1. Eject magazine, and make sure gun is unloaded
  2. Take AR-15 / M16 / M4 buffer tube and thread the castle nut onto it (notches to the rear)
  3. Slip receiver plate (notch pointing towards open end of buffer tube) onto the buffer tube
  4. Thread the buffer tube (with castle nut & receiver plate) into the adapter
  5. When the receiver plate gets close to the adapter line up the notch on it to the corresponding hole in the adapter
  6. Turn the castle nut towards the receiver plate in order to snug it up against the adapter
  7. Tighten up the castle nut using a stock wrench or your hand.
  8. Slip stock of choice onto buffer tube

Attaching the adapter to the Glock
  1. Double check that gun is unloaded
  2. Remove detent pin from the hole in the adapter insert
  3. Insert the pointed end of the adapter into the corresponding hole (behind the magwell) in the backstrap of the Glock
  4. Push up on the adapter until it hits the crest on the top of the grip
  5. Pull the upper brace of adapter around the crest of the grip, allowing it to fit into place
  6. Firmly push bottom of adapter so that the hole in the backstrap of the Glock lines up with the hole in the adapter
  7. While maintaining pressure on the bottom of the adapter, insert the detent pin (using a twisting motion) through the hole in the backstrap of the Glock and through the adapter

    The fit is meant to be tight, so this may take some effort!
