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 and Sancer barrel. 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 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 with a 13lb spring.

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.

    works good but I got a grey one to match my grey velocity slide and the color is way different? so I wish I would have just got a black comp

    Got this for my G47. I am using the velocity threaded barrel for a G17 and the Gen 5 Velocity Compensator at full compensation. Made a significant difference with my speed and accuracy with my follow up shots. I would strongly recommend using this compensator with a velocity threaded barrel because the design makes it easier to install and remove, and holds it in place and alignment far better than any of the barrels other set ups I have used.

    I purchased another Velocity Compensator and am currently using it on my PSA dagger. I am using it at full compensation with the stock threaded barrel. It was easy to set up and align, but I still like the Killer Innovations barrel because of the design has notches built in to the barrel and locks compensator in place. My speed and ability to make follow up shots significantly improved especially when compared to stock. Another great thing about this compensator is that it is easy to install and remove without any special tools, especially with the killer innovations barrels. I have multiple I strongly recommend this compensator, and if possible get the killer innovations barrel.
