You'll need cursed DLLS for step one on how to fly, why?
Because, we need to use "The OG"

Two shells just ain't gonna cut it, you can easily have a manger do all the work here.

So, you're probably asking yourself "Wait why did I download mods for my game just to use a gun that's already IN the game?"
Well, it's because The OG has a REALLY hard kick. So hard if you aim down, you'll end up about 130-140 feet in the air or so. But as said before, two shells (or four if John Woo wannabe) ain't gonna cut it.
So you can use a Saiga 12 or Spas 12 to load up more then enough shells to have you flying higher then Snoop dog at 4:20. Replace the normal 12 gauge shells with the 3 Gauge shells.
For the Saiga 12, you must empty the mag or drum first then insert the shells using Cursed DLL.

Just a warning, you can do jack squat while about 300 feet in the air. But about the guns, most don't have giant mags, or use a round powerful enough to send it's self directly into some poor sosig about 100m up and break it in half.
So this is why we also downloaded Cursed DLLs, so we can use whatever drum mag we want to put into whichever gun (mostly) we want. Like a PPSH or Kriss Vector.
(I prefer the 100 round 5.56 Drum Mag)
But what I said before, make sure they're locked and ready. You can't interact with your gun in the air for whatever reason, trust me. Ain't nothing happening up there.

So, make sure you have your shotgun and air guns strapped securely in one of your air...Pocket holes.
Make sure they're green and attached to your body is what I'm trying to say.
So first, you aim the shotgun you filled with 3 Gauge with at your feet.
Pull the trigger about 3 times, then drop it as it falls back into whatever slot you binded it to.
Pull out whichever guns you picked and spray down the general area and pretend you're a AH-1 COBRA Gunner.
I recommend folding or no stocks, as virtual stocks hurt trying to actually aim.

Don't try to aim normal
RPM > Accuracy
Single shot RPGs are a no go
Single shots are useless
Remember, if you don't hit anything. Blame RNG
You're a Suppressive tool, not a marksmen tool.
The MGL is quite nice today.
The MG42 has too much recoil.
The M249 doesn't fire fast enough.


Bye bye g.i!
