The CFD Comp finally brings real engineering analysis and design to the shooting sports.  This comp was designed and setup in a proper computational fluid dynamics model using external flow.  Using this simulation model the size, shape, and spacing of each port was optimize to create the flattest shooting comp out there.  You can see that port arrangement isn't the typical big to small that dominates the common sense designs.  As the gas expands and lowers in pressure the ports need to become larger to effectively create the forces we are looking for.  Trust the data, this is what it wants.

The other area of focus for the CFD Comp is being super lightweight.  Of course it had to be made of titanium. All excess material is removed to make this the lightest weight comp you can buy at 1.8oz.  The ports are carved deep and wide with a contoured lower section.  This lightweight design creates unparalleled balance and speed shot-to-shot.

Comps require gunsmith installation.  Each CFD comp is checked with the Brownells .685-40 tap, to run smoothly.  BUT - new barrels, like KKM come with the threads only partially cut.  This allows the gunsmith to finish cut the threads with an adjustable die to assure a tight fit between comp and barrel.  Please see video below for installation overview. 

-  CNC Machined from 6AL-4V titanium, bead blasted finish.

-  Threaded 11/16-40

-  1.8 Oz

-  Designed around a .369 ream (EGW), this is important as the size of the hole in the baffles plays directly into the port size and spacing

-  Align ream once installed

-  Review the graphs to see the effect of barrel holes.  9mm Major can run without if that's your style, or with two 3/16" holes.  1/8" don't give enough bang for the buck. 1/4" should be used by the 38 Super guys.

-  Shoot more 2 Alphas

Works great! Just a little long.

Review by Cameron Tanner on 11/16/2020

The comp works great!! It’s just a little long for me. Super lightweight, it’s half the weight of the steel cheely that it replaced


Review by Ryan on 7/24/2020

The Binary Comp works better than I had hoped for. I will be purchasing more when I build my next open gun and my steel challenge gun.

Positive upgrade!

Review by TomF on 6/11/2020

This comp is extremely lightweight in spite of it's length. The best thing about this is the way the pistol returns to zero, and the next best thing is the way the dot tracks in recoil, straight up without any wiggle. I did have to run a tap through it to fit on an Infinity barrel. I shot some slow motion video comparing it to a different product, you can view it here:

Super efficient

Review by D. Staples on 7/11/2018

This thing is crazy efficient. Make sure you have a lightened slide, heavy ammo, or a extra light recoil spring, or a combination of the three. Originally I couldn't run factory ammo in my gun until i had the slide lightened more and reduced the spring power, now it's fine. Just be sure to do plenty of testing before you take it to a match. I didn't have to chase the threads with a tap like some other comps out there, but you might have to chase the threads on your barrel though.
