Pooh Shiesty is no longer trying to delay his federal trial, which kicks off on October 25.

Shiesty is facing serious time for the Bar Harbor, Florida incident -- described as a sneaker and drug deal gone bad  -- that included Pooh firing off shots and then escaping in a Maybach.  The shootout was caught on tape

The "Back In Blood" rapper faces a maximum of 20 years each for conspiracy to possess firearms in furtherance of violent crime and for Hobbs Act robbery conspiracy.

In addition, he's facing a maximum life sentence for discharging a firearm in furtherance of a crime of violence.

If he somehow escapes his federal trial unscathed, he is facing unrelated Florida charges of aggravated battery for firing his gun in the ground during a strip club dispute and hitting a security guard with the ricochet.
