(IR)lasers often act very glitchy, it sometimes just downgrades the perception of quality of the game, example:
Also shining through objects when pointshooting etc. etc.
Making them shine in parallel with the barrel, since IR lasers are already programmed to shine from the peq unit, the point of impact needs to be shifted a few inches from the real point of impact. It can probably be calcutated with some simple algorithm, so it doesn't need to be programmed manually per gun.
Same for normal lasers, it's weird how they shine straight from the muzzle/or just points at the middle of the screen (when ads/pointshooting) which causes the glitch from the screenshot.
Also would it fix the laser glitch in 4x and 7x scopes and now properly bounce with the visual recoil. It can be used for all stances aswell (hip, ads, bipod, pointshooting). Overall it would just be more realistic and much more consistent.
