He is facing trial by judge and jury in the Circuit Court where the penalties are potentially greater after the DPP ruled that the matters were too serious for the District Court.
The accused, of The Crescent, Millbrook Lawns in Tallaght, appeared before Tallaght District Court charged with possession of 9mm ammunition rounds, 9mm rounds with their tops cut off, 12in gauge cartridges and a Beretta shotgun.
The alleged incident took place at Hunters Hall, Hunterswood, Ballycullen, on June 26, 2012.
Fowler is also charged with possession of a number of drugs, including heroin, cannabis, amphetamine, pyrrolidinovalerophenone (pvp) and cocaine, as well as having the drugs for sale or supply.
The alleged street value of the drugs was €800,000.
Fowler is further charged under Section 15A of the Misuse of Drugs Act where the alleged value of the drugs is more than €13,000.
A State solicitor said the book of evidence was ready and had been served on the accused, who goes forward to the present sittings of Dublin Circuit Criminal Court.
Defence solicitor Michael Hennessy said there was an application for legal aid, saying Fowler is unemployed and on social welfare.
Garda Sergeant Bernard Jones said there was an objection to legal aid, alleging that €118,000 in cash was found by gardai in a safe.
Judge Anthony Halpin said the Circuit Court can decide on legal aid.
Judge Halpin gave Fowler the alibi caution, warning him he had 14 days to provide to the State details of anyone he proposed calling as a witness in the case.
The judge also ordered that a video copy of an interview which gardai conducted with Fowler be furnished to his legal team.
