A pressure gauge locking structure of a paintball gun includes a rear cap and a pressure gauge. The rear cap is screwed to a rear end of a gun body and has a first end and a second end. The first end is formed with a recess for the pressure gauge to be secured therein. The second end is provided with a piston block which has a stepped hole therein. The stepped hole is disposed axially and interconnected with the recess. The pressure gauge has a guiding rod which has a threaded hole for insertion of a screw member. The pressure gauge has an air passage for interconnecting with an air passage of the piston block so that the pressure gauge is unable to be dismantled from its exterior and the user reads the pressure gauge easily.
