Three other Marines were injured Monday, CBSLA.com reported. The accident occurred at the Marine Corps Air Ground Combat Center in Twentynine Palms, near Palm Springs.
His family said the death is under investigation.
"Nick was a selfless and loving person," his cousin, Colleen McMahon, said. "Everyone called him brother. He was always volunteering to help with anything or be there for anyone -- USMC, family, or friend-related. He held the titles of corporal, Eagle Scout, son, brother, uncle, grandson, nephew, cousin and friend -- roles that are now void in so many lives."
