[KM Project] All-Metal Real Cartridge for Tokyo Marui BB Air Revolver Colt Python .357 Magnum, Speed Loader Compatible Ver. [DNR357CTSP]

Tokyo Marui BB Air Revolver Colt Python .357 Magnum Real Cartridges

These real cartridges are compatible with the Tokyo Marui BB Air Revolver Colt Python .357 Magnum and feature
machined brass bodies and machined aluminum bullets.

With a focus on weight, texture, and handling,
they provide an authentic loading and ejection experience that stock cartridges cannot match.
O-rings securely hold the BB pellets, while adjusting the bullet seating depth allows for
fine-tuning of retention and muzzle velocity.

▍Product Overview
■ Machined brass bodies and aluminum bullets

The cartridge bodies are machined from brass, while the bullets are machined from aluminum.
CNC engraving provides a realistic finish with exceptional texture and presence.

■ Substantial weight

Weighing 16 g per cartridge,
they are approximately as heavy as eight stock cartridges.
This provides a substantial feel during both loading and ejection.

■ Adjustable BB pellet retention

The cartridges feature an O-ring design to hold the BB pellets.
Tightening or loosening the bullet adjusts the retention,
allowing for fine-tuning based on usage conditions.

▍Compatible with Tokyo Marui Speed Loaders

Compatible with Tokyo Marui speed loaders for BB air revolvers

However, because the cartridges are heavy, they may fall into the extractor star when ejected using an ejector rod.

② Minimized bullet wobble

The bullets are designed with an outer diameter approximately 0.1 mm larger than those of stock cartridges.
This minimizes wobble when installed,
enhancing the overall unity and texture of the cartridges.
