The BCG Replacement Weight is meant to replace the stock weight in the back of your BCG to accept our .625 bolt extension for our Gen 3 Folding Stock Adapter. The BCG Replacement Weight does come with a 9mm coiled pin. PLEASE NOTE that this is BCG Replacement Weight has a 35° angled hole for the roll pin. Newer designs as of December 2020 may require a horizontal hole. If you have any questions please contact us first!
