Claim:
1. A tunable muzzle compensator comprising: a substantially cylindrical front member constructed to fit over a gun barrel, the font member having a hollow elongated tubular shaft with a longitudinal central axis and a horizontal and vertical lateral axis, said tubular shaft having an outer surface with six shaft gas exit holes on the outer surface, three on each side at the horizontal lateral axis, each shaft gas exit hole in opposition to a corresponding hole on the other side of the shaft: the shaft also having three removable washer-shaped tuning sections fitted over the shaft, each aligned fore and aft with one pair of shaft gas exit holes, wherein each tuning section has a pair of rearward-facing washer gas exit holes machined into the tuning section at a predetermined angle from the horizontal lateral axis to combat recoil; each pair of rearward facing washer gas exit holes also facing upward at a predetermined angle from the horizontal axis, wherein selection of the predetermined angle allows tuning the firearm for muzzle rise; whereby, a particular washer gas exit hole produces more force at its predetermined angle when it is aligned with a pair of shaft gas exit holes nearer the shooter, thus allowing tuning of the firearm for both recoil forces and muzzle rise.
