DonnyFL Air Venturi Extender 1/2"x20 UNF A70

The DonnyFL Air Venturi Extender A70 is a unique combination of a thread extension and moderator adapter designed specifically for the Air Venturi Avenger, Air Venturi Avenger Bullpup, and Umarex Origin. By moving the thread position forward, it creates additional clearance for larger airgun silencers and moderators.

Create Space for Larger Silencers

Many larger silencers can interfere with the fill port on PCP air rifles. The A70 solves this issue by extending the mounting position forward, allowing shooters to keep their silencer installed while refilling the rifle.

Improved Barrel Alignment

The extender slides over the barrel and helps maintain precise barrel centering within the adapter. This reduces the risk of pellet clipping and can contribute to improved shooting consistency.

Designed for Popular PCP Platforms

The A70 is designed for:

• Air Venturi Avenger
• Air Venturi Avenger Bullpup
• Umarex Origin

Suitable for air rifles from .177 through .25 caliber.

Industry-Standard 1/2"x20 UNF Thread

Featuring a 1/2"x20 UNF male thread, the adapter supports a wide range of airgun silencers and moderators using the most common thread standard in the industry.

CNC-Machined 6061 T6 Aluminum

The A70 is precision CNC-machined from 6061 T6 aluminum, offering an excellent balance between strength, durability, and low weight.

Matte Black Anodized Finish

A matte black anodized finish helps protect against wear and corrosion while giving the extender a clean and professional appearance.
