The ULTIMATE® Upgrade Series hop-up chamber by ASG delivers enhanced accuracy, reliability, and improved sealing for your AUG rifle. Crafted from durable CNC-machined aluminum alloy, it’s designed to minimize air loss while withstanding recoil forces during firing. Its polished inner surface reduces friction, ensuring smooth BB feeding. The design allows for precise and stable hop-up adjustment, leading to better accuracy and increased range.
Thanks to precision machining, the chamber is fully compatible with most Steyr AUG replicas by ASG and Tokyo Marui. Some users have reported compatibility with Classic Army M14 as well, though this is not officially confirmed by the manufacturer.
