Mortar says hi.
Regarding OP, its far suppression is low IMO. It needs less accuracy but higher suppression at far. Rifle nades also need range reduction when suppressed which is an ancient issue.
Why would it need less accuracy?
It already does less dps then cheaper HMG42 at that range.
Its not bad HMG, but it definitely doesn't stand up to its price in comparison to cheaper and superior HMG42.
Inb4 some amoeba comes up with "but ketetoooof, it haz suprir cloz rung di pi ez", how often do you put your infantry within 10 range of hmg frontally for extended time periods?
