Can I shoot a firearm with a ported barrel, ported slide, or compensator inside the MCK?

No. Compensators physically will not pass through the front muzzle shroud. Ported barrels and slides vent high-pressure, superheated combustion gases upward inside the closed polymer chassis. This can melt or warp the polymer structure, causing extreme fouling build-up, or pose a safety hazard to the shooter’s hand.

Barrel & Slide Limitations: Crucial Safety Warning

CRITICAL WARNING: No Ported Barrels or Compensator Slides

No MCK 1.0, 2.0, or 3.0 (Gen 1, Gen 2, or Gen 3) is compatible with ported barrels, slide-integrated compensators, or slide ports.

When a pistol with barrel ports or compensators is fired inside an MCK, burning gunpowder gases and extreme pressure vent directly upward and sideways inside the sealed chassis. This hot high-pressure gas will rapidly melt, erode, and severely damage the MCK’s internal polymer frame and charging mechanism.

Always use standard, solid-top barrels and unported slides inside your MCK.
