Five men have been jailed over the murder of a shop worker in Salford.
Nasar Hussain, 27, was shot in the chest and stomach at an off-licence in July 2009 by a hitman with a machine gun concealed in a paper bag.
Mohammed Hafiz, 43, Arfan Rafiq, 26, and Simeon Henderson, 28, were all jailed for life for the murder at Manchester Crown Court.
Two other men, Ryan Manning, 22, and Akmal Afzal, 25, were jailed for their parts in the shooting.
Manning, of Higher Ince, was convicted of manslaughter and was handed an indeterminate sentence with a minimum term of eight years.
Afzal, of Bolton, was convicted of possessing a prohibited weapon and assisting an offender jailed for seven years.
Hafiz, of Cheetham Hill, and Rafiq, of Oldham, were both convicted of murder.
Simeon Henderson, formerly of Huddersfield, had admitted murder and gave evidence against the other defendants during their trial.
Mr Hussain was not the intended target and had no direct connection to the dispute, the court heard.
Two gangs in Bolton, including the shop's owners, were involved in a feud and one called on an Oldham gang to send out a warning to their rivals.
Hafiz ordered gunman Henderson to go into Brookhouse Wines in Brookhouse Avenue, Winton, to damage the store or injure one of its owners.
Within seconds of walking into the shop on the evening of 4 July, Henderson fired a number of shots directly at Mr Hussain.
Bullets shattered bottles on the shelves behind and lodged in the wall, while customers and other staff fled the shop in fear.
The gun was found in Oldham the next day, wrapped in tracksuit bottoms.
It was linked forensically to getaway driver Manning and the trousers matched those Henderson wore in the shooting.
Police are continuing to try to trace three men wanted in connection with the murder, whom they believe have left the country.
Gulfan Khan, 36, formerly of Oldham, and Mohammed Safdar, 30, formerly of Oldham, were arrested and bailed. They have since failed to answer bail.
Tanveer Akbar, 30, formerly of Bolton, left the country at the time of the killing and was never arrested.
It is thought the three men initially headed for Islambad, Pakistan.
