Norgon thread pitch?

[Armati]

Help!

Does the Norgon ambi-catch use a special mag release button? It does not seem to properly thread on Bushmaster, DPMS, or Stag mag release buttons. I looks like it could but it might involve some cross threading.

Norgon is standard mag catch threads. The best way to ensure that you don't cross thread is to turn the mag catch button counter clockwise until you feel/heard it click, then start turning clockwise. If you have any further trouble contract Norgon/NoVA gunworks (the manufacturer of the Ambi-Catch).
