Frequently Asked Questions

Can I use this to convert a rifle-stock lower into a pistol? This kit provides the pistol-length buffer tube and related hardware; converting a rifle-configured lower to a pistol has NFA implications and should not be done without confirming your lower’s registered configuration.

Does this include a brace or stock? No, this kit covers the buffer tube and related hardware; a brace or stock is sold separately.
