I understand now. It’s not just that these two muzzle devices (the mini-comp and A2 flash hider) are geometrically similar, they are also topologically equivalent. In other words, I should have bought a muzzle brake which LOOKS like a typical muzzle brake and not a device which LOOKS like a flash hider.Well just to play devil's advocate (because it is 2AM and I have nothing better to do).
I searched out, found, and enlarged for clarity photos of your "DoubleStar Mini Comp" muzzle device using different angles than have been presented previously here.
But first here is a DPMS mil-spec A2 flash hider...
Now a cropped close up view of your device looking into the muzzle...
And finally your device looking down on the top and enlarged so we can easily see into the 5 slots (ports) ...
Note that like the A2 flash hider your device at the bore opens into a simple expansion chamber, there is no internal architecture that channels the gas toward ports either up (brake) or back (compensator).
True because the slots are on the top the gas will escape there and cause a slight downward reaction on the closed bottom of your device. But I doubt it is preceptiple different when compared to the A2 flash hider which also has a closed bottom. Matter of fact there might be more of a braking effect with the A2 because it has a larger internal surface area to work down on due to it length.
To be honest the double star device looks like a chopped down A2 flash hider with the slots narrowed which has the effect shifting the 3&9 o'clock slots up slightly.
Which is essentially what the manufacturer says on their website in the rather confusing description (AK47 Slant brake? Really?)
Mini Comp
Post-Ban compliant, the mini comp acts and feels like a compact version of the A-2 flash hider. This compensator has 5 slots on top and a solid bottom. Has the same handling characteristics as the well known AK-47 slant brake. 1/2x28 tpidoublestarusa.com
