Air Venturi Avenger / Umarex Origin | Extender 1/2 UNF Adapter | DonnyFL – Thread extension adapter

This barrel extender is a mounting accessory for air rifles that relocates the thread position forward. Made from aluminum with a black finish, it features 1/2 UNF threading and is specifically designed for Air Venturi Avenger and Umarex Origin models.

Application and use

This loop extender is designed for air rifle applications, particularly on shooting ranges. It moves the thread position forward, creating clearance for larger moderators that would otherwise need removal during rifle filling. The extender also provides a visually extended barrel appearance.

Integration and compatibility

The adapter is compatible with air rifles featuring 1/2 UNF barrel threading. While designed for Air Venturi Avenger and Umarex Origin models, it works with any air rifle using this thread standard. The universal platform designation indicates broad compatibility across suitable air rifle systems.
