In Call of Duty: Modern Warfare, you can build a bunch of powerful, secret, or nasty weapons, but what about the craziest weapon modifications? We have tested 5 of such crazy weapon setups for you in combat.
After a hard grind on Shipment to level up another weapon to max level, there’s nothing better than some playtime at the gunsmith.
This can create the craziest weapon setups, which are often discarded with a smile. I looked at such calibers more closely, turned my cap backwards, and tested the trashiest setups of Call of Duty: Modern Warfare for you.
So if you want to bring laughter to the lobby or show your buddies that you can rock the match with these crazy setups, make a note of these insane builds.

The Gunsmith Complains, But Goes Along With It
The gunsmith looked a bit skeptical but eventually gave the green light for a few test rounds. Normally, every visit to the gunsmith should improve the weapons, but not this time. Today we are cranking the weapons through the grinder and see if these curiosities play as crazy as they look.
There were a few unexpectedly positive surprises. In particular, one setup does a damn good job despite its intrusive appearance. The aesthetics aren’t everything.
These are the crazy setups:
- Nerf-Gun – A Scar that somehow manages to be taller than longer.
- Giant Deagle – An exaggerated Desert Eagle built for size, not for sense.
- The LMS – The PKM as a sniper doesn’t work? Unfortunately, it does!
- Flint – Handgun with unnecessary shotgun properties.
- Toothpick – An Oden with inappropriate length.
Nerf-Gun – FN Scar 17
The shape strongly resembles products from a company that shares the name with the greatest enemy of any weapon in shooters. But even without Nerf, this weapon performs poorly.

What attachments do I need for this?
- Barrel: FORGE TAC Close Combat Pro
- Laser: Tactical Laser
- Scope: Scope
- Stock: FTAC Foldable Stock
- Underbarrel: 40mm Recon
How does the nonsense play? This weapon not only looks like a water squirt gun, it plays like one too. Not really good at any distance and with little water in the tank, uh, bullets in the magazine, you always need the element of surprise. But if you decide the match for your team with this piece, you’ll have the props on your side.
With the recon attachment, you can support your team from the back row, and the sight helps with long shots. But this bulky thing doesn’t really convince. Better stick to water balloons.
Giant Deagle – Desert Eagle
Even the normal variants of this weapon offer no real advantage for professional use. This overloaded thing belongs in a display case, as a scare for grandchildren with the inscription “Hands off!” or right in a weapon museum.
What attachments do I need for this?
- Muzzle: Tactical Suppressor
- Barrel: FORGE TAC Executioner
- Laser: 1mW Laser
- Scope: VLK 2.5x Scope
- Grip: Rubberized Grip Tape
How does the nonsense play? Anyone who has ever held a museum piece will regret it at least after spending a night in jail. But with this shooter, you’ll regret it immediately. The optimal setup to improve your handling with the Desert Eagle. If you can manage to score here as well, you’ll sweep everything away with the good builds.
Otherwise, if your K/D means something to you, look at this variant only from a distance. The stability is quite nice, and accurate hits take out opponents, but your firepower is restricted to that of a musketeer due to the small magazine and slow handling. So keep your hands behind your back and hands off this exhibition piece.
Light-Machine-Sniper – PKM
While this weapon does not produce one-shot kills, it’s fine if a shot goes off target. The magazine offers at least 90 misses, making it a perfect entry into a successful sniper career – or maybe a quick end.

What attachments do I need for this?
- Muzzle: Monolithic Suppressor
- Barrel: Extended 26.9″ Barrel
- Scope: Scope
- Stock: FORGE TAC Stalker
- Underbarrel: Grip
How does the nonsense play? Don’t rely on the weapon, but on your skills as a constant camper. If you get seen, don’t even try to take out the opponent. Take your legs or your secondary weapon in hand and come up with a new plan. Even our tips for snipers won’t help you here.
However, the feel of the weapon is surprisingly good. With the attachments, this LMG with an identity crisis provides decent stability, and any random headshot kill feels rewarding. At least until the campsite manager comes by and asks you to only grill on the marked areas.
Flint – .357 Revolver
This pistol-shotgun wishes to be a hunting rifle, but the shotgun bullets hardly go beyond grip reach. With the scope, you can observe enemies from a distance before they take you out.
What attachments do I need for this?
- Laser: Tactical Laser
- Scope: Lockwood Pistol Scope
- Trigger: Robust Trigger
- Ammo: Shotgun Shells
- Grip: Lockwood .357 Special Stock
How does the nonsense play? The noble wooden stock conceals the clumsiness of this modified revolver, but from the very first shot, you’ll get to know the uncomfortable nature of the weapon.
If you adjust to the short range, you’ll get a quite solid shotgun with a hefty kick. With the scope and attachments for better aiming, the shotgun shells provide reliable one-shots in their small area. This way, you get a decent shotgun without having to use “Overkill”.
Toothpick – Oden
You shouldn’t underestimate this setup, even though it looks really crazy. Despite the good possibilities to enhance the dental hygiene of close enemies, it is regarded as a strong build for the Oden.
The long Colossus suppressor already makes you smile due to its incredible length. The barrel and stock add a few unnecessary centimeters to the device. Your buddies will laugh at you in the lobby, but here you have a real killing machine, leaving maximum assists for your teammates.
These are the attachments:
- Muzzle: Suppressor (Colossus)
- Barrel: Oden Factory 810 mm
- Stock: FTAC XL Elite Key
- Underbarrel: Command Foregrip
- Grip: Textured Grip Tape
How does the nonsense play? The assault rifle really takes off with this build. The stock, the grip tape, and the missing sight bring the otherwise poor ADS speed of the Oden to a bearable level, and with the giant suppressor, barrel, and grip, the range becomes enjoyable.
Among all the crazy setups, you should really try this one.
Building weapons in Modern Warfare like never before
The game offers diligent crafters a ton of attachments that should all be tried out. Some of the many guns play “naked” like eating applesauce with your hands, but with the right attachments, clumsy tools turn into really strong weapons and perhaps even new favorite guns.
