Since i have sniper build with skills to semi-auto fire and component damage, i use my AG4 to accurately hit machine’s components. I mainly use AP rounds but when i’m low on AP, then FMJ as well.
For close combat, the 4x zoom is a bit much but i prefer to keep distance between me and machines (so, i won’t be surrounded). Close combat can’t be avoided entirely and for that, i have my HP5.
Interesting fact about HP5.
When game launched, Kpist had the lower dmg per bullet than HP5 but less recoil, higher RoF and bigger mag. Making HP5 better SMG when it comes to the dmg per bullet, if you can handle it’s recoil. At some point, devs switched the dmg per bullet around and now, Kpist has the dmg per bullet HP5 used to have.
This is still seen from GZ wiki where weapon stats are unchanged,
6* m/49 wastes ammo against runners since it takes only 1x HE rocket to drop a runner, wasting 2nd shot. Unless you aim 1st shot too low where 2nd shot hits. But it’s great against hunters. One salvo is enough to drop FNIX hunters, if you hit with both rockets.
