Too short, doesn’t seat on buffer. - Anarchy Outdoors Tactical -Folding- Bolt Carrier Extension JP Law

Does not work with Sylvan folding stock adapter and Armaspec Stealth Gen 4. Was too short for stock buffer as well. Anarchy website says, the Armaspec SRS Stealth Recoil Spring is not compatible with our folding bolt carrier extension. However, the SRS can be modified to fit (False), doesn’t work, too short.

The Sylvan Arms SA5P Light BCG Extension worked.
