The blowback unit (BBU) is a key internal component in gas-powered airsoft guns. It is typically located inside the slide or bolt and serves as the structural housing for the blowback mechanism.

During firing, part of the released gas moves the slide or bolt rearwards while another portion propels the BB through the barrel. This blowback action creates the recoil effect and prepares the gun for the next shot.

The BBU (blowback unit) supports and guides several internal components inside the slide. Parts in this category may include:

Blowback Housings
internal slide mechanism components
structural parts for blowback systems

Many upgrade components are manufactured from CNC-machined aluminium or reinforced polymer, providing improved durability and consistent operation.

In this category you will find BBU units and related parts for gas-powered airsoft guns, compatible with various airsoft platforms and manufacturers.

Whether you're replacing a worn component, servicing your airsoft gun or upgrading internal parts, this category includes BBU units and related components for gas airsoft platforms.
