Acetech Quark C M870 Tracer Unit

The Acetech Quark C is a specialist barrel-mounted tracer unit specifically engineered for the Tokyo Marui M870 Breacher series, offering a seamless, integrated look for shotgun-based CQB dominance. Designed to fit securely over the muzzle, the Quark C provides a sleek, "built-in" aesthetic that allows for instantaneous illumination of every BB in your 3-round or 6-round bursts.

For the tactical shotgun operator, the Quark C is a revolutionary upgrade. It transforms the M870 Breacher from a standard close-quarters tool into a devastatingly effective night-fighting platform, giving you the visual feedback needed to track your spread and adjust your aim in low-light environments.

Core Specifications & Performance

• Bespoke M870 Muzzle Integration: Designed specifically to mount directly onto the barrel of the Tokyo Marui M870 Breacher (and compatible clones), ensuring a perfect fit that maintains the original lines of the replica.
• Multi-Shot Tracking: Advanced sensors are calibrated to detect and illuminate multiple BBs simultaneously, ensuring that every pellet in a 3 or 6-shot burst is bright and visible.
• Rechargeable Lithium Battery: Features a high-capacity internal battery charged via USB-C, providing thousands of rounds of illumination on a single charge.
• Smart Power Management: Automatically enters sleep mode when inactivity is detected to preserve battery life, waking up instantly upon the slightest vibration or movement.
• RGB LED Technology: Supports green tracer BBs and provides high-intensity output that is visible even in transitional light settings.

The "Pro" Take

In our technical workshop, we consider the Quark C the gold standard for shotgun tracers. Traditional tracers on a shotgun often look like an afterthought and can interfere with the balance of the RIF. The Quark C solves this by hugging the barrel's silhouette. For players who run a "Shotgun-Primary" loadout, the ability to see exactly where your spread is landing at 20 metres is an massive advantage. It turns a "point-and-click" weapon into a precision instrument, especially when paired with high-quality green tracer BBs.

UK Spec & Site Performance

On the UK circuit, the Tokyo Marui M870 Breacher is a staple at indoor urban sites and repurposed industrial venues. The Quark C is perfectly suited for these high-speed environments. Because UK indoor sites are often pitch-black in certain sections, the Quark C acts as a psychological weapon as much as a tactical one - there is nothing quite as intimidating as a 6-round glowing spread coming down a dark hallway. It is fully compliant with UK safety standards and doesn't affect the FPS of your RIF, ensuring you stay well within the standard 350 FPS (or 1.14 Joule) limits for UK indoor play.

Friendly FAQ

Will this fit the full-sized M870 Tactical or Gas Tank versions?
The Quark C is specifically designed for the Breacher model's barrel profile. While it may fit some other variants with similar outer barrel dimensions, we recommend it primarily for the Breacher to ensure a flush, aesthetic fit.

Can I use red tracer BBs with this unit?
The Quark C is optimised for Green Tracer BBs, which provide the brightest and most consistent glow. It may not effectively illuminate red tracer BBs.

Is it difficult to install?
Not at all. Installation is a straightforward process of mounting the unit securely over the existing muzzle. No permanent modifications to your RIF are required.

Does it have a muzzle flash mode?
The Quark C focuses on high-intensity BB illumination. While the LEDs are powerful, it is primarily a tracer unit rather than a dedicated flame-effect simulator like some of Acetech's other "Blaster" models.
