Once again, I (original author Diakyuto, the same below) would like to say that almost 80% of this comes from the weapon of the same name in Antistar's WARS package. Please show your support by trying WARS for yourself and giving your endorsement. This is actually a weapon I REEEAAALLLYYY want to make at some point. So while I still have some pump action shotgun inspiration, I put together my take on the Mossberg mod.

The M590 Pump Action Shotgun is a versatile shotgun platform that can be crafted as either a cutoff or standard straight-grip shotgun, making it a highly sought-after weapon. Welding one of these is a status symbol among Bostonians. If you were using a pump action from my Ithaca or T6M it would be like an alternative play style as this one is more straight forward, 12 ga rips, and has the ability to turn into a pistol. (inb4 That’s not a pistol XDDDDDDDDDDDDDD)

It contains:

Standard pump casing

4 barrels

2 magazines

6 grip options (including 2 pistol grips)

2 iron sight options

Luminous sights

3 Reflex sight options

2 combat sights

5 long-range sights

Laser module

Choice of wood and polymer materials

A variety of Creation Club style camo!

There is also a unique one called the M590 Shockwave for sale by Tom the Blacksmith at Railway Headquarters.

You can find it on the Level 18 Bodyguard, Gunslinger Sniper, Railroad Agent, and Far Harbor Predator Boss.

Q&A (Question and Answer)

Q: “This is not realistic at all”

Answer: Tough luck!

Question: “bethesda le bad, modder le good” comment

A: Reddit is on the left side of the lobby.

Q: Does it work with power armor?

Answer: Yes. Part. First Person Work A-OK. Third person shotgun animation with lever action reloading. Therefore, you can still reload independently.

Q: Can I translate this mod?

Answer: Of course!

Q: Can I patch another ammo mod or my favorite overhaul?

Answer: Of course!

Q: Can you extract directly from WARS?

Answer: Do it yourself. When I make mods like this, I try to make my stuff transformative. Antistar deserves recognition for their hard work. If you do this, I recommend you do the same.
