Killer Innovation’s Velocity Compensator is “braking” all the rules! This compensator significantly reduces recoil and muzzle climb and attaches in an innovative new way that is completely different than any other compensator on the market. This revolutionary attachment system has a few advantages over the traditional methods.

First: It can be installed and removed without using tools when using our Velocity or Sancer barrels. Cleaning your gun just got a whole lot easier! When used with other brand barrels, tools will be required to add or remove the comp, but accuracy will be maintained.

Second: The compensator pushes all the way back to the thread shoulder when installed. This provides a superior bore alignment to other comps that are timed short of the shoulder, then set screwed or clamped to the threads. This bore alignment accuracy ensures the bullet is passing directly down the center of the comp with an equal air gap around the bullet. This equal air gap eliminates the air pushing to one side and wobbling your bullet. Accuracy down range is the ultimate goal!

Every professional shooter we let shoot this comp during testing said this was the flattest shooting comp they had ever shot. We agree! We adjusted the ports and tuned this comp for months before we were satisfied that we had made it shoot as flat as possible and still reliably cycle the slide.

If you want a compensator that is extremely accurate and installs easier than any other comp on the market, look no further, we’ve got you covered!

As always, made 100% in the USA.

    This comp was easier install than why I thought. Works great with the velocity v1 slide and threaded barrel. Shoots so flat. I love the look too. All around a fantastic compensator.
