The JK Armament 155 Pro flash reducer end cap is a titanium muzzle device designed for 30-caliber suppressors and similar threaded applications. This isn't a traditional brake or flash hider—it's a precision-engineered cap that threads onto 1.375"×24 TPI barrels to manage flash signature while maintaining a clean appearance. If you're running a suppressed 30-cal rifle and want a durable, lightweight solution that doesn't add unnecessary bulk, this titanium construction delivers the reliability you need in a compact package.
Built from Ti6AL4V titanium (the same alloy found in premium suppressors and aerospace applications), the 155 Pro resists corrosion and handles the heat cycles of centerfire rifles without degradation. Titanium's strength-to-weight ratio means you're not adding measurable heft to your barrel crown, which matters when every ounce counts on a hunting rifle or precision build. The black finish maintains a tactical aesthetic while the material itself simply outperforms steel alternatives in longevity.
Installation is straightforward—it's a direct threaded fit for 1.375×24 TPI barrels, so verify your barrel's threading before ordering. This is purpose-built for suppressor users and precision shooters who want a quality end cap that won't corrode, rattle loose, or require constant maintenance. If you're building or upgrading a 30-caliber rifle and need a durable, lightweight muzzle solution, JK Armament's titanium construction offers the durability and simplicity serious shooters depend on.

The JK 155 Pro is designed for barrels threaded to 1.375"×24 TPI. Verify your barrel's threading specification before purchase—incorrect thread size will prevent proper fitment and safety.
The 155 Pro is an end cap—it threads onto your barrel to cap a suppressor or similar muzzle device. It's not a standalone flash hider and is intended as part of a complete suppressor setup.
Titanium (Ti6AL4V) resists corrosion better than steel, weighs considerably less, and handles repeated heat cycles without degradation. For shooters who suppress and shoot regularly, titanium's durability justifies the material choice.
You receive the JK Armament 155 Pro end cap only. No tools, shims, or additional components are included—it's a direct threaded installation.
