Yesterday I wrote that firing the Law Tactical AR-15 Folding Stock Adapter with the stock open could damage the user. This was incorrect and the post has been updated.

The manufacturer says …

The Bolt Carrier Extension part, when installed correctly, will hold the Bolt Carrier Group in place.

The Bolt Carrier Extension will also stop the Bolt Carrier Group from flying out and causing any injury or loss of life if someone should accidentally fire the weapon with the stock folded. If fired when folded, the locking finger will bend, preventing further operation of the weapon until it is replaced. This is done to eliminate the possibility of catastrophic failure of the adaptor due to repeated misuse.

I apologize to the manufacturer for making this error.
