Sounds like you are talking about the Browning M1919A6 .30 cal. machinegun




The last variant was an attempt to make the M1919A4 lighter and handier for infantry use. The M1919A6 featured a buttstock and bipod, as well as, a flash hider. While the weapon was supposed to be more useful as a light machine gun, it was still heavy compared to contemporary weapons in the role, and was generally not regarded favorably.
