Progressive 7-port design diminishes gas pressure evenly to counteract recoil and virtually eliminate muzzle flip. Each top port decreases in size gradually, offering balanced pressure release, and is angled 7° forward to eliminate scope lens hazing. Can be cutoff behind the forward side port for a shorter, lighter comp. Plenty of room for a relief cut on the bottom to allow a government-length guide rod and reverse plug on commander-length guns. Precision CNC machined from high-grade steel, stainless steel, and titanium.
