JK Armament 155 Pro High Flow End Cap 30 Cal 1.55" Titanium Black

The JK Armament 155 Pro High Flow End Cap is a tactical suppressor accessory purpose-built for JK Armament's 30 caliber JK 155 series suppressors. Built from lightweight Ti6AL4V titanium in a black finish, this end cap is engineered to dramatically reduce flash signature while keeping overall suppressor weight to a minimum.

Featuring three aggressive prongs and built-in gas vents, the Pro High Flow End Cap is JK Armament's most advanced tactical end cap design. The high-flow configuration maximizes gas venting for reduced flash, turning your JK 155 suppressor into an effective flash-hiding muzzle device without sacrificing suppressor performance. The end cap measures 1.55" in diameter and threads directly onto the rear of any JK 155 series 30 caliber suppressor.

Whether you run a JK 155 RCX, RPX, or another 30 caliber variant in the JK 155 family, this titanium end cap delivers a duty-ready appearance with real functional flash reduction. Lightweight Ti6AL4V titanium construction preserves the shootable weight of your suppressor platform while adding the aggressive visual profile preferred for tactical applications.
