WATCH: Rob Gronkowski spends his offseason firing minigun

Rob Gronkowski has had a roller coaster of an offseason, and he's unwinding by firing a minigun.

Gronkowski posted a video of himself firing a minigun in slow motion on his Instagram Monday.

Gronkowski has had quite the offseason, with miniguns and Supercross event filling his free time.

The Patriots tight end had his home broken into while the Patriots were in Houston for Super Bowl 52, and he said on Instagram that he has a new form of defense for any burglars.

"Taking some lessons on how to use my new home security," Gronkowski wrote in his Instagram caption.

Patriots fans don't have to worry any longer, as he confirmed in April that he'd return to the field in 2018.
