A 23-year-old Tampa man already on probation for a violent past was hit with nine new felony charges this past week after detectives searching his home on the 300 block of Pecos Way say they found an operable machine gun, a bump-fire stock and hidden conversion devices designed to turn ordinary firearms into rapid-fire weapons. Allen Hasani Greenidge Jr. was arrested Friday, August 7, following the search, according to the Hillsborough County Sheriff's Office.
Detectives with what the sheriff's office refers to as #TeamHCSO served the search warrant at the Tampa residence and seized several firearms, various ammunition and narcotics, according to a Hillsborough County Sheriff's Office post detailing the arrest. Among the weapons recovered were a Smith & Wesson M&P handgun that investigators say was modified into an operable machine gun, an American Tactical .223/5.56 rifle, and three internal devices described by the sheriff's office as “incognito” machine gun conversion parts.
Greenidge was already on probation at the time of the search, having previously been convicted of aggravated battery with a deadly weapon and domestic battery by strangulation, and he now faces probation violation charges tied to both of those prior offenses. He also faces charges of felon in possession of a firearm, felon in possession of ammunition, possession of an operable machine gun, and possessing a bump-fire stock, per the sheriff's office post.
Drug and Property Charges Add to the Case
Beyond the weapons counts, Greenidge was charged with armed possession of a Schedule I controlled substance with intent to sell or deliver, along with owning, leasing or renting property for the purpose of trafficking, selling or manufacturing a controlled substance, according to the sheriff's office. The search stemmed from what detectives described as an ongoing firearms investigation.
Court and arrest records reviewed by Recently Booked show Greenidge had already been arrested in Hillsborough County in December on marijuana charges and probation violations, meaning he was under active supervision tied to his violent prior convictions well before detectives showed up on Pecos Way this month.
What Florida and Federal Law Say About the Charges
Under Florida Statute § 790.221, possessing an operable machine gun is a second-degree felony carrying up to 15 years in prison, 15 years of probation and a $10,000 fine, according to Pumphrey Law. Florida law defines a machine gun as a weapon capable of firing more than one shot automatically without the shooter manually reloading between trigger pulls.
Separately, Florida Statute § 790.222, passed as part of the 2018 Marjory Stoneman Douglas High School Public Safety Act, makes importing, selling or possessing a bump-fire stock a third-degree felony punishable by up to five years in prison, according to FindLaw. The law made Florida one of the first states to independently ban bump stocks and rate-increasing conversion kits at the state level.
The three internal conversion devices found in Greenidge's home could also draw federal scrutiny. Under 18 U.S.C. § 922(o), federal law treats machine gun conversion devices — including internal switches and auto sears — as machine guns in their own right, carrying federal prison sentences of up to 10 years, according to the Giffords Law Center. The ATF treats standalone conversion parts as illegal machine guns even when they are not installed on a firearm, and whether federal agencies will adopt this case remains an open question.
As a convicted felon, Greenidge also faces exposure under Florida Statute § 790.23, which makes firearm or ammunition possession by a felon a second-degree felony carrying up to 15 years in prison, with actual physical possession triggering a mandatory minimum three-year sentence, per the Ansara Law Firm.
Part of a Broader Sheriff's Office Crackdown
The Pecos Way raid fits a pattern the sheriff's office has pursued aggressively in recent years. Sheriff Chad Chronister established the Gunfire Response Investigations Team, known as GRIT, in July 2021 specifically to investigate non-fatal shootings, gun trafficking and illegal firearm offenses across Hillsborough County. The unit works with federal partners including the ATF to analyze ballistic evidence and dismantle local illegal weapons networks.
That focus followed a period when statewide violent crime in Florida rose 2.5% between 2019 and 2020, with Hillsborough County recording the highest number of violent crimes in the Tampa Bay area, prompting officials to form specialized task forces. In August 2023, the sheriff's office reported deputies arrested three people in Plant City after seizing four firearms — including one fitted with an operable machine gun conversion device — and 2.6 pounds of marijuana, with Chronister saying at the time that deputies were targeting individuals using auto-converters to terrorize neighborhoods.
The Pecos Way case also echoes recent Hoodline reporting on similar busts. In July, Hillsborough County detectives executed a search warrant that uncovered 12 guns and bump stocks along with 75 THC cartridges at a Tampa home, leading to felony charges for two suspects. And in February, a search warrant in Dover turned up 11 machine-gun conversion devices along with firearms and drugs, in a case that also began with a probation compliance check before detectives secured a warrant for a secondary structure.
Greenidge was arrested on nine felony charges in total, according to the sheriff's office. No additional court proceedings or federal charging decisions have been reported as of publication.
