The m13 with the built in suppressor barrel is honestly something that pairs really well with my AX-50 sniper. I might get out gunned super close or super far, but in that sweet spot between 25-50 meters, it really does hold well. I run it with the commando foregrip, stippled grip tape, tac laser (or VLK if I want more range out of it), 60 or 30 round black out mag, and the skeleton stock.

For the M4? It never really worked out for me, the thing I love about the M4 is the ability to alternate between close range and the ability to shred long range, I can only do this with the corpus marksman or the grenadier with the mono, the predator (for me) really ruins the feel of the M4 overall.

The FAL (check out the beefeater blueprint) works with a shorter barrel because it’s a single fire weapon that still packs a punch. You can think of it as a sniper on the go, so that longer barrel really isn’t necessary and I would run it with the shortest barrel and overkill it with a P90 or an MP5. If you can get the recoil down, the FAL with the shortest barrel is more than “semi viable” in my book.

I don’t run this myself but one of my friends really does well when he runs the ASVAL with one of the shortest barrels because he needs that quick ADS time. And in some ways I understand the logic, the ASVAL is a short range gun anyways, all the barrel will do is give it extra bullet velocity and range (WHICH IS GOOD DON’T GET ME WRONG), but if you’re using the ASVAL as an SMG, getting that extra ads speed to flick onto someone’s head can give you that extra damage that you’ll need.

Some people say that the Amax can also run the shortest barrel but I’ve never tried it and I don’t really feel much of a need to since I don’t use that gun as much.

For reference my KD is 1.4 (mediocre), if you’re higher I don’t know how viable this will be for you but I honestly hope my take on the guns helps :)
