The Velocity Compensator from Killer Innovations is an excellent tunable compensator with several unique and exciting features.

Revolutionary Attachment System

The Killer Innovations Velocity Compensator uses a new revolutionary attachment system, which allows it to be mounted on Killer Innovations Velocity or Sancer barrels without using any tools. Additionally, unlike traditional compensators that need to be timed short of the thread shoulder and set screwed in place, the Velocity Compensator’s revolutionary attachment system allows it to be pushed back to the thread shoulder when installed. This results in superior bore alignment and improves accuracy.

Precision Engineering

Made in the USA, the Killer Innovations Velocity Compensator for Sig P320 has a durable and rugged design. It is made to fit within the profile of the Sig P320 for a seamless appearance and is available in multiple finishes.
