RCA Music Group senior vice president Bryan Leach faces two years in prison.
Leach has worked with a roster of rappers including Lil Jon and the bilingual Spanish/English artist Pitbull.
He pleaded guilty Monday to attempted weapons possession.
The New York Post says he left court without commenting.
He was arrested in 2010 for driving through New York City with a gun loaded with hollow-point bullets.
He remains free pending his sentencing on Nov. 8.
