A firearm-design and statistics system for GURPS, covering weapons from TL4–8, including rare antiques, prototypes, custom guns, and heavy artillery. Using details such as caliber, barrel length, action, projectile, muzzle velocity, and weight, it provides rules for calculating game statistics consistent with existing weapons.
