The HQM here is a rounding error. What you really spend is one tech trash and scrap from the Level 3 research list, where explosives and the guns themselves stand in line first. So ask where that tech trash does the most.
On a gun you hold on target for a long time. A bolt watching a doorway drifts less, and the HMLMG gets the steadier aim its long belt needs. On an AK that already wears a holosight, a laser is a second tech trash for a smaller gain.
Laser and sight sit in different slots, so one gun can carry both. The recycler hands the tech trash back only some of the time: move lasers between guns, don't recycle them.
