Hailstone

Hailstone is Haru Yamamoto's secondary sidearm in End War Online, used when she needs a higher firing rate than her main rifle and primary sidearms offer.

Design
The Hailstone is based off the Daewoo K7 submachine gun, which features an integral suppressor by default. The modifications made to this include: While Haru defaults to her Avalanche pistols for a sidearm, there are times when they aren't the right gun for the job. In those instances, Haru switches to the Hailstone with its 3-round burst, semi-auto, and full-auto firing rates. She only owns two of these, but only uses one since the other is a back-up copy in case she loses the first. The gun itself features silver overlays on its black body, with blue and black "hazard striping" and minor gold outlines as additional cosmetic changes.
 * Redesigned, sleeker frame with an integrated stock that reduces recoil
 * A quad-rail system at the front to mount attachments as necessary
 * Modified internals designed to increase damage and accept a variety of 9x19mm Parabellum bullets, like anti-angel or anti-demon rounds
 * Side-mounted Laser sight
 * Trijicon ACOG TA31-ECOS-RMR BAC Rifle Scope
 * Vertical foregrip/flashlight module
 * Ergonomic handgrips with magnets for better grip
 * Short-pull trigger

Trivia

 * Keeping in line with Haru's sniper role, the Hailstone is yet another weapon that features an integral suppressor in the weapon's unmodified form.
 * Haru actually had to research the internet for a submachine gun she could use as a viable secondary sidearm, eventually coming across this gun. When she first purchased the gun, she seemed slightly dissatisfied with its appearance, but found it to be perfect as her alternate sidearm. Following its first use in one of her contracts, she had it modified to what it is now and has been satisfied with it ever since.
