Barrel Extension Adaptor for Colt MKIV – Thread relocation adapter

This extension adapter relocates the thread of your Colt MKIV air rifle forward, creating space for mounting suppressors or other accessories that would otherwise not fit. Features 14mm CCW threading for secure attachment and aluminium construction for minimal weight addition.

Construction and materials

Manufactured from aluminium with a black finish, this loop extender provides durability without excessive weight. The adapter uses a threaded mounting system with 14mm CCW specifications, ensuring a solid connection to compatible air rifles while maintaining structural integrity during use.

Application and use

Designed for recreational shooting and target practice applications. The extender shifts the thread position forward, enabling suppressor mounting when the original thread sits too far recessed, or to create a visually extended barrel profile. Particularly useful for Colt MKIV platforms where standard accessories cannot mount due to thread positioning.

Integration and compatibility

Compatible with airsoft platforms featuring matching thread specifications. The 14mm CCW barrel end threading accepts standard suppressors and muzzle devices. Specifically engineered for the Colt MKIV series, though may fit other models with identical thread patterns. Verify your rifle's thread type before installation.
