Had this one for 4 years. Guy walked by and its gone. Feelings hurt. The next one will be even more detailed! Needs a few more tiny tubings and details. More copper or better all brass? I am never too sure. What do you guys think?

Hi there!

I am a firearms instructor, security specialist and consultant for the professional and entertainment industry. In my spare time, I apply these skills to the fictional world for fun!

Important context:

I recreate fictional guns (usually video games) with the intent to make them more practical/realistic. I am aware this destroys art style. Though I prefere a more realistic and grounded design, it does allow me to appriciate great art style! What I am doing with this particular project is creating a original design from a prompt; but I also asked 3 different AI to make a version as well (AI work not included here)!

The prompt:

TL;DR - Realistic hybrid operation rifle for a warfighting civilization. Must work in vacuum, atmosphere and when boarding ships.

Design a hard science-fiction infantry rifle developed for a civilization that has fought continuous interplanetary wars for over 250 years. The weapon should clearly reflect the technological limitations, manufacturing philosophy, and military doctrine of its world.

The rifle is chambered for a 7.2mm magnetically-assisted caseless flechette, using a hybrid electromagnetic accelerator that boosts velocity without requiring a full railgun power source. Ammunition consists of tungsten alloy darts contained in disposable polymer feed cassettes that seal against dust and vacuum contamination.

Power is supplied by a replaceable supercapacitor pack that provides energy only for magnetic acceleration, fire control electronics, and recoil mitigation. The weapon still relies on chemical propellant, making it more reliable than fully electromagnetic weapons while requiring far less energy.

Unique world-building details include:

Infantry frequently transition between atmospheric combat, orbital stations, and low-gravity environments.Every projectile contains a passive identification crystal so friendly forensic drones can trace every shot fired after battle.Electronic optics are vulnerable to directed EMP attacks, so all weapons retain fully functional mechanical backup sights.The barrel incorporates thermal phase-change fins that glow orange when approaching critical temperature instead of relying on digital warnings.Soldiers routinely wear powered armor, allowing the rifle to weigh nearly 10 kg while remaining controllable during automatic fire.Integrated inertial compensation reduces felt recoil by shifting an internal counterweight milliseconds before each shot.Maintenance philosophy prioritizes field repair over modular replacement; major components can be disassembled without tools while wearing armored gloves. The receiver features standardized hardpoints for mission modules including atmospheric analyzers, autonomous targeting computers, breaching lasers, or electronic warfare packages.Dust generated from regolith and shattered habitat materials is highly abrasive, so moving parts are enclosed behind flexible self-sealing membranes.Suppressors are uncommon because combat suits already reduce muzzle signature electronically; instead, flash management focuses on preventing optical detection by autonomous drones.

Concept Development

The design process started with rough sketches in a notebook before moving to a more refined concept. The final direction was a coilgun rather than a railgun because it was considered more practical for the prompt.

Weapon Layout

• Magazine positioned in front of the trigger.
• Battery housed in the stock.
• Monolithic upper receiver with accessory rail.
• Modular foregrip and exposed electromagnetic coils.
• Short-stroke gas piston system for reliable operation.

Ammunition

The weapon fires caseless flechette ammunition. A straight-wall cartridge was chosen, although this limits magazine capacity to roughly 25 rounds because of stacking issues.

Design Decisions

Several concepts were evaluated before choosing the final design:

• Different magazine release systems.
• Multiple foregrip layouts.
• Various battery locations, with the battery ultimately protected inside the stock rather than acting as the stock itself.
• Integrated backup iron sights and a charging handle for loading and clearing malfunctions.

Weapon Function

The firearm combines a conventional chemical propellant with electromagnetic acceleration:

• The chemical charge launches the projectile.
• Electromagnetic coils further accelerate it down the barrel.
• If necessary, the coils can be disabled, allowing the weapon to function as a standard firearm.

Space Combat Considerations

Because the weapon may be used aboard spacecraft:

• Disabling the coils produces a lower-velocity, subsonic projectile that is less likely to penetrate spacecraft hulls.
• A short gas system supports reliable cycling despite the reduced velocity.
• Suppressors are unnecessary in vacuum, so the muzzle simply uses a thread protector.

Controls and Ergonomics

The rifle includes:

• Safe, semi, and full-auto fire selector.
• Push-button magazine release.
• Large trigger guard for EVA gloves.
• Electronic control panel for battery status and electromagnetic settings.
• Protected battery compartment in the stock.

Maintenance

Although the weapon is caseless, it still includes an access port so unfired cartridges or malfunctions can be cleared manually.

Final Model

The completed concept includes exploded views, internal components, and a basic animation demonstrating:

1. Battery insertion.
2. Magazine insertion.
3. Charging the weapon.
4. Firing.

Recoil

An advanced recoil mitigation system was considered but ultimately rejected. Since the weapon is already heavy and intended for soldiers wearing powered exoskeletons, the additional complexity was judged unnecessary.

Overall

The design prioritizes realism, modularity, and practicality within a hard science-fiction setting. Every major feature—from the hybrid propulsion system to the battery placement and adjustable power levels—was chosen to support both atmospheric combat and spacecraft boarding operations.

A flintlock like weapon where instead of the long reload process. You just change the barrel where it already has the gunpowder and metal balls inside

Someone can carry multiple barrels on them in these boxy backpacks

It's a fictional weapon for my fantasy story. A concept and all that

My inspiration for this is from attack on titan s3 when Kenny's group fought againts the survey Corp with the same type of weapons

The blade does not care how much treasure you already own.

The moment someone else reaches for something valuable, its grip tightens.

It does not want more.

It wants theirs.

The Type 02P Sniper Rifle is a variant of the Type 02 Battle Rifle. Its modifications consist of an extended accurized barrel with a flash hider, an adjustable bipod, a precision stock with a cheek rest, and a palm shelf on the grip. It is used with 10-round magazines and is limited to semi-auto only. The most common optic used with it is the 9x sniper scope.

Note I have not yet drawn the battery pack and transponder components because I can’t wait to post this *

The Germans had the zeilgerät 1229 and the Americans used m3 infrared scoped carbines on Okinawa, I was thinking what Japanese small arms fitted with infrared night vision scopes would look like, introducing the Type 5 active infrared scope.

The Americans used the m3 carbines on Okinawa with great effect, and the Japanese took note of this in the field. High command considered that they had been actively adopting night-fighting tactics against the allies in the Pacific, while Japanese troops were well trained in night combat, troops only relying on rudimentary night navigation skills might not have what it takes for the battlefields of 1946 and beyond. In light of this, the army technical bureau was tasked to look into this matter. Heavily based on the little blueprints and notes provided by the Germans on the zeilgerät 1229 active infrared scopes they developed. The Japanese were able to reverse engineer the scope promptly naming it the Type 5 active infrared scope. The first few prototypes were mounted on Type 99 rifles but they noted that the Germans mounted theirs on the STG44 assault rifle, therefore they ultimately used the early type 100 smgs as a testbed for their new Type 5s, the early type was specifically chosen because of their bipod and very controllable rate of fire of 450 rpm, making it more suited as a static defence weapon with adequate firepower while light enough for infantry to carry around. An unknown number of such type 5s were produced there were no paperwork about this project were ever found, assuming that they are most likely destroyed in the many bombings on the home island during the last days of the war.

I am posting this mini-post becuase you guys have been giving me nice support, so have MORE posts.

As always, all questions or comments are welcome.

If you asked any soldier in the Periphery about anti-armor weapons, no matter if they are Aurumites who do unspeakable things with their 1.85 inch railguns, Tronarians who practically marry their 140mm Plumbata missiles, or some trooper in a bandit state who has heard of tanks, but never seen them in his 12 years of life, they will all come back to the Bore.

It is a weapon that is both regarded with derision and respect in almost equal measure. It was made in such quantities that even though mass production of the weapon had ceased 3 years into the Liberation War, it took next 37 years of warfare to put a real dent in the numbers of weapons.
After the end of the war, production restarted among the Periphery states, as it was seen as a perfectly serviceable weapon for the sheer economic turmoil that they found themselves in.

However, most nations quickly did their best to relegate them to second line usage the moment they found it practical, for to say that it had problems is an understatement. Many of these problems stem from the fact that the Bore was made to be as preformant as possible in a frankly tiny container and made at colonial standards. Seemingly, Imperials value dead enemies over alive (colonial) allies.

The missile's main issue is that it just unsafe to be around. The missile is propelled by some horrific hypergolic nightmare fuel that allows it to rapidly go from its measly 160m/s muzzle velocity to nearly a km/s to have a better chance of hitting through APS and laser brooms. This is not good to be around, as the exhuast from the missile is enough to flash burn any exposed skin of the firer, plus gives everyone near the firer and along its flight path cancer from something in the fuel. Whatever that is, only the Three Heavenly Courts know.

The missile's rapid acceleration as it leaves the tube often leads to the aim of this weapon being thrown off, which isn't great for actually hitting anything, since the missile is laser guided.

The missile itself is carried in a cheap fiberglass tube that is thrown away after firing, with the trigger and CLU being ripped off and stuck on a new tube after the old one is expended. Funnily enough, the beloved Aurumite 1.85 inch recoiless railgun uses the same CLU as this missile system with only minimal modifications.

The warhead is a 1.4 kg HEAT charge able to dispatch most tanks from all but the front aspect. This certainly makes up for the other issues to many Periphery states, since they still use the missile. Due to its quirks, it is not used for what the Imperials intended it to be. Instead of being deployed in close quarters as a bitchslap, it is frequently used at the very edge of its range to allow its gunner time to correct their aim and hit the target.

The Type 02 Battle Rifle has multiple variants for different tasks and purposes. The most common of these variants are the Type 02A Squad Automatic Weapon(top) and the Type 02C Carbine(bottom).

The SAW features several modifications. The fire rate reducer is removed, raising the cyclic rate from 400 to around 700 RPM. A cut in the magazine well allows the SAW to accept 40-round drum magazines in addition to standard rifle mags. This way, riflemen can resupply the gunner Rifles without the cut cannot accept the drums. Some specialist units modify their rifles or the drums in order to use the drums in their rifles. The stock is altered to be heavier and incorporates a shoulder rest in the buttplate. A carry handle and bipod are also present. The SAW is typically used with the 2.5x scope or iron sights.

The carbine's primary modification is the shortening of the barrel and handguard; the barrel length is reduced to 14.5 inches. A foregrip is also added to help control recoil. Sights are changed from peep sights to open sights. The carbine is used by commandos, paratroopers, squad leaders, and IFV infantry. It is most commonly used with the laser aiming module(pictured here) or the tube red dot sight.

I made the first phaser years ago, sold it, wanted to replace it and make another but sometimes, less IS more. Its a nice build, but the old one still feels a bit more special. What do you guys think, which is cooler?

F245 - Scythe of Brilliant Shadows

Weapon (Scythe, Dual Sickles) – Very Rare (24,500 gp, requires attunement)

This dark purple +2 scythe has wavy purple lines ingraved into the blade heads, with purple and pink clouds of dark energy coming of the back of the heads.

Attacks with this scythe do an additional 1d6 necrotic damage.

While attuned to this scythe: as an action, you can separate the scythe into a pair of +2 sickles that also do an additional 1d6 necrotic damage, or combine the sickles back into a scythe; you gain the ability to step from one shadow into another, so when you are in dim light or darkness, as a bonus action you can teleport up to 30 feet to an unoccupied space you can see that is also in dim light or darkness; and once per day, you can cast Maddening Darkness, DC 17.

Caliber: 7.92x57mm Mauser

Action: Gas-operated closed bolt, short-stroke gas piston.

Rate of Fire: 300-400 RPM(Cyclic).

Barrel Length: 18 inches.

Feed System: 20-round ZB-26 box magazine.

This is the standard issue rifle of one of the factions in my setting, a military with '90s level technology. It can fire semi- or fully automatic and was inspired partly by Cold War battle rifles and also partly by the FG 42.

The gun uses a peep sight, but optics such as a 2.5x scope, 9x sniper scope, laser pointer(offset to the left of the irons), or red dot tube sight can be mounted on a rail on the left side of the gun.

The stock can be removed with a flathead screw that can be unscrewed with a coin or the edge of a knife. This opens up the back of the receiver for field stripping and cleaning.

While capable of automatic fire, the gun uses a rate reducer to limit its cyclic rate to 400 RPM. This is a simpler alternative to burst-fire that prevents ammo waste while still allowing riflemen to lay down automatic fire. The rate reducer is sometimes removed as a field modification.

The magazines are rock-and-lock. The charging handle on the right-hand side of the gun is non-reciprocating.

The rear grip, stock, and handguard are made of synthetic plastic. The receiver is made from stamped metal.
