The Gunspring

Close up of mechanism consisting of gear and spring. CLockwork. Monochrome.

Rain hissed on the gargoyle's back. Mist spewed through its crooked teeth like spittle. Lizbet set an elbow on the snarling thing's shoulder. Cold damp seeped into her skin. She leveled a heavy gunspring, tucked its sculpted stock fast against her shoulder.

She brought her eye to the scope, squinted. A hundred meters down, black umbrellas milled in the brick courtyard. Faces flash under the dripping canvass domes. She examined them, centered each in turn under the scope's cruciform reticule. A ginger man. A pockmarked woman. A teenager with a red nose. Then, standing in the crowd, a silver mask: The anonymous guise of an aristocrat.

With a thumb, Lizbet flipped the gunspring's priming catch. A high, slithery whine emanated from the weapon, the sound of the maincoil shivering as it tightened the 152 kilogram launch spring. A steel flechette dropped into the receiver with a clunk.

Lizbet sighed, emptied her lungs. Her body stilled. The reticule drifted over the masked man, steadied. Her finger tightens on the trigger.

A crack of slamming metal broke the air. The stock bucked. In the courtyard below, the masked aristocrat jerked as 300 grams of steel found their mark in his brain.

Rising from the damp gargoyle, Lizbet slipped, unseen, into the rain.

The Gunspring

Invented in 3.221 by a Firlish inventor named Guillotine, the gunspring is the current evolution of torsion-based ballistic technology. It is a handheld weapon which uses a weighty pair of compression springs to project metal flechettes.

Gunspring technology is, in many ways, a progression of the crossbow. It utilizes the same firing form and stance, and involves the use of similar ammunition (a steel bolt.)

Crossbows and gunsprings are different in several, crucial respects. While a crossbow may be drawn and loaded by the strength of a person alone, gunsprings rely on mechanical means. This is requisite, as modern launch springs are far too heavy to be drawn by a human. This mechanization is a net benefit to the weapon, as heavier springs allow more energy to be put behind the projectile.

Mechanization also allows for a marked increase in rate of fire. While a crossbow may be loaded and fired merely thrice in a minute, a gunspring equipped with a heavy maincoil may expel six flechettes in a span of several seconds.

The addition of a maincoil, is the most important element of gunspring technology. Advances in odite-based alloy permit massive quantities of energy to be stored in a hairspring coil the size of a cake tin. Torsion generated by this coil (mounted on the front of the weapon) spins a cog which drives a reciprocating, internal tooth-arm, which in turn draws and nocks a pair of heavy launch springs.

As a maincoil may draw and redraw the launch spring at a rapid rate, the addition of an ammunition magazine and feeding mechanism allows the weapon to fire without pause to reload. Thus, magazines are matched by maincoils wound with enough power to draw the launch spring a number of times equal to the magazine's contents (usually six flechettes.) Users of gunsprings carry a coil for every magazine.

Though coils and magazines may be swapped in moments, coils themselves take a deal of time to rewind. The assistance of a specialized lever is required to hold and coil in place and wind it. This may be done by hand using a field cranequin or with a lever-mill driven by a draft animal. The former winding option takes a great deal of time. It is used by soldiers in the field, who complain of the many thousand winch-cranks required to fully wind a coil. The later is expedient, but available only at armories and camps.

Tactical and Cultural Effect

Though the mighty gunspring has relegated the crossbow and reflex bow to the past, it has not doomed the art of melee. The gunspring's rapid salvo may dominate the opening throes of battle, but its slow reload time allows for melee combatants to close. Most soldiers would rather draw a sword and duel rather than reload whilst stationary, anyway. As a result, armed forces carry gunsprings in compliment to axes, pikes, and swords, rather than as a replacement.

In civilian life, single-action gunsprings are used as hunting weapons alongside crossbows. These weapons lack both magazine and coil. Their springs are drawn via cranequin.

Maximization and Instability

Theoretically, a gunspring need not be limited to a mere six shots before reloading. This limitation is cautionary, rather than mechanical.

Gunsprings coils (and, as a result, most magazines) are limited to in size and power as they become unstable at extreme tension. When wound, an alloys hairspring possesses great potential energy. Excessive jostling may cause the spring to bust, spewing razor lengths of twisting, shrapnel-like wire.

Thus, high-power maincoils possess deadly potential. They allow a gunspring to fire an exceptional number of flechettes before reloading, but also carry the risk of deadly accident.

Author's Note

The gunspring was theorized as a ballistic weapon which possessed powderless steampunk charm, satisfying power, and the terrible temptation of even more power. I believe that every nice thing in the Coast (and in RPG gameplay) should have at least one terrible downside/sin. The gunspring epitomizes that. It's a semiautomatic crossbow (woo!) that you can make more powerful (woo!) but will also explode into razorwire if you mishandle it/roll a critical failure (aww, shoot.) 

Anyway. I'll post the stats I've made for gunsprings in AD&D2E and RuneQuest, sometime.

Also, I'm aware a gunspring is (probably) impossible in real life.
