Allstar Tactical has a new compensator out now. The Hexcon1 is a hexagonal shaped compensator. It has three expansion chambers. The top of the compensator has three ports, one for each chamber. This helps reduce muzzle climb. They keep the bottom of the compensator closed so as to not disturb any dust from low shooting positions near the ground. The Hexcon1 retails for $95 and is available on their website.
