Frequently Asked Questions

What is the Angstadt Vanquish barrel assembly?

The Angstadt Vanquish is an integrally silenced 9mm AR-style barrel assembly featuring a unique baffle-less design. It's available in 16-inch or 10.5-inch configurations and aims to provide a cost-effective suppressed shooting experience for AR platforms.

How does the baffle-less suppressor design of the Vanquish work?

The Vanquish uses gas ports in the barrel to bleed pressure into a surrounding suppressor tube. Without a front exit hole, gas is contained until the bullet exits the muzzle, reducing pressure and noise through volume expansion, simplifying cleaning and eliminating baffle strike risks.

What are the key benefits of the Angstadt Vanquish barrel assembly?

Key benefits include a competitive price point ($650 for the barrel assembly), easier cleaning due to the baffle-less design, elimination of baffle strikes, and the potential for a single tax stamp on the 16-inch version. Threaded ports can also be plugged for velocity tuning.

What ammunition performance was observed with the Angstadt Vanquish?

Testing showed 115gr Fiocchi averaged 1106 fps (borderline subsonic), 115gr Winchester averaged 1307 fps (supersonic), and 150gr Sellier & Bellot subsonic averaged 900 fps (reliably hearing-safe).
