The FC1 Flechette Launcher is a four barrel weapon that features the range of a rifle while having the advantages and effectiveness of grenades. This shoulder-launched weapon holds one canister per barrel, and two canisters in a reserve chamber. Due to this configuration, a trooper can load the weapon with multiple canister types; the trooper can select the desired canister (not in the reserve chamber) by lightly tapping on the trigger. For maximum effectiveness (and dispersal) the canisters should not be programmed to detonate on impact (else performance is considerably lowered), but instead be targeted to detonate 0.10 metres ahead of the target. The user using the range finder must manually program each canister's range at which it will detonate, however, in a predicament the user can have the canister detonate on contact.

    This weapon is a widely employed among the Corporate Sector Authority's security forces. Other users of the FC1 include the Empire, as well as the Rebels. Two different types of canisters are fielded by this weapon which are designed to swat multiple targets in close proximity. Anti-Personnel Canisters are small globes containing hundreds of flechettes that are capable of terminating an entire section (squad) of soldiers in a single well-placed shot. Upon reaching the target or desired distance the globes detonate, affecting an area of ten metres in diameter. Therefore, the FC1 is excellent for eliminating clustered groups or improving the odds of hitting a single target.

    Anti-Vehicle Canisters which are larger in size are deployed to the target via an 11 centimetre long missile with a shaped charge. This charge concentrates the razor-sharp flechettes in an area no larger than five metres in diameter. These flechettes are powerful enough to tear through ten centimetres of durasteel armour plating - enough to destroy lightly armoured repulsorcraft or snowspeeders. After passing through the vehicle's armour, the flechettes proceed to destroy internal electronic systems, flight equipment, power generators, weapons and unfortunate crew members. In short, the damage inflicted is catastrophic.
