The 2 series has channels to add surface area aiding heat dissipation.
Its architecture has been improved from the classic layout of the linear compensator.
As a result, the six side holes are no longer parallel with the bullet hole, but at a slight angle for a swirl effect.
Also, the front end of the compensator is optimized to increase the effect of bullet stabilizing.
The outside diameter is .920",. At the rear there are 2 flats for wrench for easy installation.
