Loud clapping erupted from supporters in the public gallery in Masterton District Court as Ronald Charles Peacock was sentenced to home detention.
The 42-year-old of Carterton, who had been remanded in custody since he threw a loaded sawn-off firearm out of his car window after assaulting a rival associate's adult daughter, previously pleaded guilty to charges of assault, unlawful possession of a firearm and driving while disqualified.
Lawyer Michael Bott said there was a background of "long extensive provocation and harassment" between his client and the victim's father and argued home detention was an appropriate one as his client was making positive changes.
"There are strong mitigating circumstances ... He is changing his lifestyle. The prospects are encouraging," he said.
Judge Barbara Morris said it was dangerous for Peacock to have thrown a loaded rifle onto the street.
