Got a $20 linear compensator. Installed it last night. Will try shooting it this Friday.
Had a chance to take a closer look at the brake / compensator that I took off. It is a modified A2 bird cage flash hider. The front is closed up to have a smaller exit hole. Doing so gas is trapped and forced to exit through the upward port holes, and hence the over compensation. Using a step bit, I enlarged the hole. It is still not like fully open as in the original flash hider, which is verboten by the state law. I will put it back on to see how it works.
This has become a tinkering project.
The muzzle has caked up with carbon residue. Next time I change out the muzzle device, I will take a closer look at the crown. I may tinker to polish or even recut the crown.
