The Angstad Arms Vanquish is an integrally suppressed barrel for .22 LR rifles that eliminates the need for expensive subsonic ammunition. Instead of traditional baffles, the design uses a series of ports along a thinned section of the barrel to bleed gas into an expansion chamber, dropping the projectile below the speed of sound.

Key Specifications

• Integrally suppressed barrel with no internal baffles
• Ports bleed gas into an expansion chamber to reduce velocity
• Full-length rifling engagement for improved accuracy
• Compatible with inexpensive, high-velocity ammunition

Pros

• Eliminates the cost of specialty subsonic loads
• Full barrel engagement of lands and grooves improves accuracy over Israeli-style integral designs
• No baffles to strike or maintain

Cons

• Requires a dedicated expansion chamber, adding bulk
• Performance is specific to .22 LR; not a universal suppressor solution

“This means that there is no need to purchase expensive specially subsonic loads. And really, the cheaper the ammo, the better,” the host noted. “The Vanquish also provides better accuracy over Israeli style integral designs because the projectile receives the benefits of a full barrels engagement of lands and grooves.”
