🔩 What is Included with Each Barrel?
Every individual 9" threaded barrel order comes securely packed with:
The custom 9" extended match barrel variant.
A matching, knurled steel Thread Protector cap to safeguard your muzzle crown threads whenever an active suppressor or brake is unmounted.
⚠️ Slide Length Installation Notice: Please verify your exact slide length prior to setup. For example, the compact 9mm barrel is optimized explicitly for standard Glock 19/Dagger compact slides and will not function
with extended, longer slide profiles (like a Dagger Compact X or Glock 47 slide setup) due to physical tilt-angle geometry constraints during cycling.
