This is a replacement bolt extension for our Gen3 Folding Stock Adapters that have a smaller bolt extension diameter at .531 to fit FX9 and other AR9 builds that have a smaller bolt carrier group. To ensure proper fitment please measure the opening to your BCG. Not all AR9’s require a smaller bolt extension and can work with the standard .625.

If you have any questions please contact us before ordering.
