Step one: get free "grenade launcher" muzzle attachment from random gun parts company.
Step two: toss it around gun room numerous times because its in the way and has no REAL use.
Step three: get an idea and chop that sucker in half. ..
Step four: Chop the front and round the edges
Step five: bore it out with a hand drill because you don't own a lathe and like to "wing it"
I still need to tap and install. I'll probably put some vent holes along the top (maybe 10, 12, and 2 o'clock?) to help reduce muzzle climb. Not 100% sure yet.
