The JK Armament Pro High Flow End Cap in .30 cal (brand part no. JK155PROHFEC30) is what JK calls its most advanced, tactical end cap. It is the PRO version, machined from 6AL-4V titanium, and it carries three prongs and built-in gas vents that dramatically reduce flash signature while improving gas flow. The diameter is 1.55 inches, and 1-1/2 inch wrench flats handle installation without special tools. It is aimed at shooters who run a .30 caliber JK suppressor and want the lowest flash the line offers.
