I failed to notice a thread for the lovely creations of entrepreneur My Gun.
So I'm starting one.

Here, allow me to start:

The CSP45 (Civilian Silent Pistol 45 caliber) is designed around the concept of giving one person rapid, quiet, controllable firepower. Based off the M16, the CSP45 is chambered in the .45 Caliber, with built in compressor, and is shipped with silencer. It is designed to be fired with one hand in case of emergency. The firearm is very quiet, capable of firing off three rounds with about the same noise as a gravel bouncing along a paved road. However, because of the cheap quality and mass-producing, this being one of a few RaC firearms designed for civilian use, the firearm is rather inaccurate, and is hell to get loaded and unloaded. Field-stripping is nigh impossible, do to usage of Alan bolts. The sights are decent. The stock is made of pure fiberglass and plastic, making it very unconformable to fire for extended periods of time. The silencer fails to operate after seventy shots. The internal compressor explodes after about two hundred rounds are fired, causing the gun to become louder, but slightly more accurate.
The original working title was the SCP45, standing for Silent Civilian Pistol .45 caliber. After copy-write disputes, RaC was forced to change it to the CSP45.

The GW-45 (Guerrilla Warfare, 45 caliber) is built with one thing in mind: fighting dirty. From the literal standpoint of the internals, capable of functioning during a sandstorm, to the fire-speed selection switch, allowing rapid fire, slower (but still fully automatic) fire, or single-shot, to the collapsing stock, to the fairly common round, the GW-45 is designed to fight dirty.
The bottom variant, the GW-50SV (Guerrilla Warfare, 50 Caliber Sniper Variant), is designed for mid-range sniping. The scope is adjustable, and the weapon has been up-scaled to fit the larger .50 caliber round. The metal and plastic the gun is designed from is also a darker shade of grey, allowing for basic camouflage.
Both are designed around rapid and dirty fighting. The GW-45 is your standard troop gun. The GW-50SV is your standard scout-sniper's weapon.
The GW-45 suffers from one major issue: Weight, or lackthereof. It is very light, coming in at 10 pounds (4 Kg) unloaded, and 18 pounds (8kg) loaded. On top of this, the lack of a rail leads to issues when attempting a flashlight mount, although that can be solved with duck tape and a flashlight.
The GW-50SV also suffers from the same issue, it feels much too light. Border-line cheap feeling, most scout-snipers will most likely feel afraid to use it, do to the cheap-feeling build quality and heavy round combination, leading to the rumor of the gun exploding when fired. 14lb (6kg 350.29g) unloaded, 23lb (10kg 432.62g) loaded.
