An armed gang - the youngest aged 13 - who carried out four raids in a week on Merseyside have been detained.
Sentencing the five, Judge Mark Brown said their case "highlighted the scourge of gun crime... which permeates some parts of Liverpool".
Bradley Beveridge, 18, Declan Kilbride, 16, Declan Culshaw, 15, Dylan Currie, 14, and Jobe Kilbride, 13, all admitted armed robbery.
Their sentences at the city's crown court ranged from four to nine years.
In one raid at an All In One convenience store in Norris Green, Liverpool, Beveridge threatened a shopkeeper with a sawn-off shotgun while Jobe Kilbride vaulted the counter to steal from the till.
Currie also joined in, rifling through the till as Culshaw kept watch at the door.
Taxis held up
As they fled, the shop owner's friend Mani Mohan, 31, was shot in the face as he tried to confront them. He received pellet wounds to his neck and face.
From 30 April to 4 May, they also held up two taxis in Norris Green and robbed the Quickhomesave store in Walton.
Beveridge, of Springbank Road, Anfield, Liverpool, received an indeterminate sentence for public protection with the recommendation he serve at least five-and-a-half years.
Declan Kilbride, of Tarbock Road, Huyton was detained for nine years while his younger brother Jobe Kilbride got a four-year term.
Currie, of Breeze Hill, Liverpool was detained for six years while Culshaw, of Sandyville Road, Clubmoor, Liverpool got a five-year sentence.
Speaking after the sentencing, Det Insp Andy O'Connor, of Merseyside Police, said: "We constantly warn about the dangers of firearms and the use of firearms.
"These weapons are not toys and in the wrong hands can cause serious injury or even death to offenders using them, and more importantly to innocent members of the public who may be nearby.
"No matter what age they are, they do have a choice.
"They do not have to get involved in gun crime and I think the sentences handed out today reinforce that."
