The 2 series has channels to add surface area aiding heat dissipation.
Linear compensator is designed to direct the gas on a forward direction, away from the shooter. 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.
All Nano Linear Compensators are 1.5" long.
