No. At least not in any way you could call a test. A buddy has one and for the couple rounds I put through it it seemed impressive, but that doesn't really mean anything without taking any measurements, and a comparison only works if you use the same rifle for multiple brakes.
I did thread the holes in my Hypertap so I could tune it the same way the Gen3 APA's work. The concept works for sure.
I absolutely love mine that I use on my Precision rifles, APA has always seemed to make a very effective MB as for as recoil reduction goes but being able to tune the muzzle rise and shift is just outstanding.
