AceTech Kriss Vector THOR (BIFROST) QD Tracer Suppressor - Black

Designed to match the KRYTAC KRISS Vector, the AceTech THOR (BIFROST M) is a premium QD tracer suppressor for SMGs that turns every burst into a show. You get bright green tracer BB illumination for perfect shot tracking in dark CQB, plus a stunning RGB muzzle flash simulation that looks brutal on video and even better in person. If you want “Star Wars” flight paths with a real-firearm style flame effect, this is the Vector upgrade to beat.

Built for the KRISS Vector: true QD snap-on mounting

• Vector-specific QD fit: snaps directly onto the original KRYTAC KRISS Vector flash hider for a clean, factory-style look.
• Fast on / fast off: ideal for players who swap between compact and tracer setups depending on the field.
• Removable BIFROST M module: detach the tracer core for easier charging and maintenance.

BIFROST M tracer + RGB flame effect

• Green tracer BB support: instant illumination for clear visibility throughout the flight path.
• RGB muzzle flash simulation: realistic flame bursts with 11 color options, including effects like Rainbow and Dynamic Rainbow.
• Standard & Sniper illumination: choose full-time lighting or Sniper mode that illuminates every 3rd BB for a tracer-round style pattern.
• Most impressive on gas guns: the flame effect can light up escaping gas for an even more realistic blast look.

All-weather skirmish ready

• IP64 protection: dust resistant and protected against splashing water.
• USB-C rechargeable: convenient charging with a typical full charge time of about 2.5 hours.
• Long runtime: up to 24,000 BBs in tracer mode (flash modes reduce total runtime).
• Smart power saving: auto sleep after 5 minutes of inactivity, shake/move to wake.

Recommended setup
