Earlier this week I received my approved form 4 for a YHM Titanium suppressor. The ATF has recently been turning around electronic form 1s in around 30 days. At the time of this writing form 4s can only be submitted by paper. So if you are looking for a machine gun/suppressor be prepared to wait. However, I will say that 5 months is much better than the 11 months I waited for my Octane 9 to clear.

If you are looking for information and/or predictions on NFA wait times, silencershop has a created a tracking system that provides are very accurate representation of the ATFs progress. See this link:
