The 5KU CNC Aluminum Hammer Spring Housing is a direct upgrade for the Tokyo Marui 1911 GBB airsoft pistol, engineered to replace the stock polymer component with high-performance aluminum.

Constructed from a solid block of aluminum via CNC machining, this housing ensures precise tolerances for a perfect, wobble-free fit inside the pistol frame. This rigidity eliminates flex, stabilizing the hammer assembly for more consistent cycling and a crisper action during use.

The unit features a durable anodized finish that resists scratches, wear, and corrosion while maintaining a clean, professional look. A non-slip diamond texture is machined directly onto the surface, providing a secure and positive palm grip that remains reliable even in wet conditions or during rapid shooting.

An extended lanyard tail is integrated into the design, allowing for the secure attachment of a safety lanyard. This feature is essential for tactical players who need to ensure their sidearm remains tethered and accessible if dislodged from the holster during dynamic movement.

In short, this housing delivers enhanced durability, improved grip texture, and added tactical functionality for the TM 1911 platform.
