    Can't tell if Tzeentch is just trolling us or is being super serious.

    He's probably a heretic.

    You know if you think about it, our current technology is actually on par with what the 40k universe has. (to some limited degree)

    If someone put in the time I'm quite positive that someone could easily fabricate a functional bolter complete with the armor peircing, rocket propelled, grenade ammunition that they use.

    Some of the other weapons unfortunately are still outside our grasp such as the las, plas, and eldritch heretical muck floating around in that universe.

    I wish a gun manufacturer would kickstart a bolter build, at least for shits and giggles.

    They already built a bolter:

    Kinda odd that the top-of-the-line gun of the SPEHSS MEHREENS is the one that we can build, but the crappy lasgun that can be made everywhere is far out of our reach.

    That's kinda of neat, I forgot all about that gun. (yes I have heard of it before) However I would like someone to make a bolter, simply because I think it would be rather amusing.

    Kind of makes you think about the next iteration of future bullets/rounds. Imagine if caseless ammunition got off the ground and was viable. (Technically it is, but mostly for artillery or slow firing weapons.)

    Imagine if we figured out how to make something like a lasgun, (the trick is working around the atmosphere or "gas obstruction") thinks would be greatly different.

    Ugh we need a holy god emperor of mankind already to force us to rise from the ashes of this filth.

    The trick is not "working around the atmosphere", it's figuring out the energy storage. And the energy density in the gun itself. Atmospheric losses aren't that big of a deal at weapons-grade laser strengths, especially if you choose your wavelength carefully. Attenuation for 1064 nm in normal air isn't too bad, you only get real problems when you have either far infrared or extreme UV wavelengths.
    Let's see: A viable lasgun would fire a pulse train containing energy comparable to a rifle, so let's say 2 kJ to have a bit more than a 5.56 mm NATO bullet, and to make the number nice and round.
    Let's say the pulse train be composed of 100 pulses of 20 J pulse energy each, spaced 5 µs apart. The pulse division is important to let the plasma that is created at each hit to collapse and dissipate to optimize penetration. That doesn't sound like that much, but believe me, this is beyond any laser technology right now. 2 kJ in 500 µs yields an average power of 400 kW. And 20 J per pulse is ridiculous at this repitition rate. The biggest pulse energy I worked with was with a flashlamp-pumped Nd:YAG laser that could deliver up to 80 J per pulse, but at super slow rep rates, yielding 200 W average power maximum.
    And then you'd need to develop energy storage that could store enough energy for a few shots at least.
    Nope, handheld laser weapons are seriously far off. In the end it will always be more efficient to just lob your energy cell at the enemy and blow him up directly.

    What about heat? For a system to use so much power there has to be some kind of heat radiation otherwise the think would just slag components. Unless maybe those components are easily swapped out. (still talking about hand held lasers)

    How about we just go the coilgun route? I have seen some rather interesting designs that use a circle hopper to bring projectiles up to speed with limited parts. Basically the hopper increases the speed of the projectiles inside to a allow all the shots be at the maximum that the coilgun can allow. However if the projectiles build to much speed the thing kinda of rips itself apart. I personally think its an issue of reinforcing the components and some high tech doodly dads.

    Yeah, cooling is another issue. High power lasers are usually connected to a water cooling system. And lasers are inefficient, so there will always be a lot of heat.
    Coilguns and railguns have the same problem with the energy storage, in the end any electrical storage is currently a lot less efficient than chemical storage.
    And coilguns have other issues, for example the extremely fast switching necessary, and the trade-off between high magnetic field and inductivity. You want the accelerating magnetic field to be high, but a coil that can create such a field will have high inductivity, so you can't switch it on that fast.
    Railguns then require intense mechanical bracing to withstand the forces during acceleration and will have massive wear on the rails.
    Coilguns, too, because the fast switching and intense magnetic fields will also exert massive forces on each coil. So in the end you'll get a very heavy gun that can't do anything a normal gun can't do. Small, light, and fast projectiles aren't necessarily the best thing.
    Electrical guns are just not for handheld use, as sad as it is.

    Let us say energy storage would be no issue at all. What about range? How would such a laser weapon compare to a sniper rifle chambered in 5,56? Those can be if I remember correctly effective on ranges of up to 900 meters, albeit you would have to be a really good shot to hit on that range. I guess accuracy would be less of an issue with a laser, since well, it's light.

    Range is dependent on weather conditions, weapon focusing aperture, and wavelength. Accuracy would be nigh perfect, but you'd be limited by what your focusing optics can do. A small spot size at an extreme range requires large apertures in your focusing optics, so it's unfeasible for a handheld weapon, and you can't really get around the diffraction limit any other way.
    The weapon range then depends on your target material, harder material require higher intensities/smaller spot sizes, softer material you can also shoot at longer ranges.
    I'd say about 900 m for flesh. If it's raining, everything's fucked, of course.

    Also, fun side effect: If you use weapons-grade lasers in a civilian setting, make sure to tell the civilians, because even scattered light will severely fuck up your eyes at these energies. If such weapons existed you'd get a LOT of crippled eyes.
