That's something I didn't think of and could very well be what's happening. Thanks for the thought. I have some experimenting to do.

This rifle is a perfect example. Shoots POI = POA with the thread protector on, 2-3" high 1' right with the Recoil Eliminate (Tank brake) installed and 7-8" low 1/2" right with the Tactical brake installed. I was expecting the POI to change when installing and removing the brake(s) but the temporary change when removing the brake and reinstalling the thread protector really had me baffled.

Again thanks for the insight.
Guns are not dangerous! People are! RKBA!
