 M84 - 7.62mm Machine Gun
Kao i svi drugi mitraljezi, M84 je namenjen za uništavanje neprijateljske žive sile, vatrenih sredstava, neoklopljenih i lako oklopljenih vozila, a može se koristiti i protiv niskoletećih ciljeva u vazdušnom prostoru.
Mitraljez M84 koristi municiju 7,62x54R sa običnim, teškim, probojno-zapaljivim, obeležavajućim i probojno-zapaljivo -obeležavajućim zrnom.
Zato je, pored varijante mitraljeza, M84 uveden u naoružanje VSCG i kao standardni puškomitraljez umesto PM M72, čime je znatno povećana vatrena moć pešadijskih jedinica.

 3C272.1 = B1222+131 = M84 Evidence for Supermassive Black Hole   (Site not responding. Last check: 2007-11-02)
Observations of the spectrum of the nuclear region of M84 with the Hubble Space Telescope's Imaging Spectrograph (STIS) show evidence for fast rotation of a disk of gas at the center of the galaxy.
The left side of the spectrum displays the shorter wavelengths (light emitted by gas that is moving towards us relative to the center of M84); longer wavelengths (light shifted further to the red because it is moving away from us faster than the center of M84) are to the right.
The radio source is believed to be powered by winding up magnetic fields in the inner part of the gas disk, a process that can accelerate fast-moving particles and magnetic fields along the rotation axis of the disk and thus launch the radio jets.

Opening up the box, my first impression was just how small the M84 is. This isn't an earlier version of the 92 or even a cut down 92 (a la compact carry 1911s), but a scaled down version.
The fit and finish is excellent and the markings are deep and sharp, unlike the fake markings often found on KSC guns, of all types.
I believe WA procure genuine Beretta grips and those on the M84 certainly look very similar in finish and quality to the real steel ones I had on my Elite.
