Builder Michael Herron watched materials from his bankrupt building firm next door to his home being removed by liquidators over four days.
But after having a drink he confronted them and gave them five minutes to clear off the site while carrying a single-barrel shotgun.
However, the gun was not loaded and a court heard he was now remorseful for what he had done.
Herron, (60), who is now earning a living in Nigeria, was told by Judge Conal Gibbbons in Dungloe District Court that he wished him well in his work and hoped he could build himself back up again.
However, the judge also said what Herron did "would have frightened the life" out of the liquidation staff.
Inspector David Kelly said during the investigation gardai discovered Herron was intoxicated when he gave the liquidation staff five minutes to leave the site at Clooney, Portnoo, Co Donegal while he was carrying an unloaded shotgun.
Gardai later arrested him in his niece's car. They recovered 12 shotgun cartridges at his parent's home following the incident on February 9, 2011.
Herron gave a pledge to gardai that he would not apply for a firearms licence in future .
The judge said he acknowledged that Herron, a father of five, was truly remorseful and was unlikely to commit further crime.
He adjourned the case until July to give Herron an opportunity to pay €1,000 compensation to each of the two liquidator employees ordered off the site.
