"Haven’t poked the parent police bear in a few days," 43-ear-old Hart captioned the video.
"Willz and I shooting the 22 rifle. She is getting pretty good. Can hit a 12 inch pie plate from 30 yards."
"Started her shooting at 3yrs old," Hart revealed. "For the record [none] of us hunt, just enjoy shooting for sport. I’m raising the kids with knowledge of fire arms, how to handle them, shoot them, store them, and avoid them in uneducated hands. #knowledgeispower"
Carey’s post has sparked a fierce debate amongst his followers.
Whilst some praised Pink’s husband for teaching their daughter gun safety at a young age, others thought it was irresponsible for a seven year old to be handling a gun.
"That is your opinion. I never slam people for speaking their opinion," Hart wrote in response to a negative comment. "I enjoy debate and shedding light on subjects that are sensitive like this. Now when you disrespect my country or 'culture' I feel I have every right to get nasty."
In December Hart came under fire for his parenting style after posting a picture of his and Pink’s then two-year-old son Jameson riding a dirt bike, prompting Pink to take to social media to defend her husband.
"How often have you spent time with my husband? How often have you watched him parent? Do you know my children? Are you aware of their development? Even better: What are your credentials in Parenting expertise? Are you a perfect parent? S**t, are you even a parent? A psychologist? A teaser? These are bold statements from a social media spectator."
Carey was also criticised last year for taking Jameson out in public when he had the contagious viral infection hand, foot and mouth disease.
