HCA Knurled Thread Protector

The HCA Knurled Thread Protector is a clean, durable solution for protecting exposed muzzle threads when a suppressor, brake, or other muzzle device is removed.

Machined in Idaho from 416R stainless steel using USA-sourced steel, each protector features 5/8-24 internal threads and a precision-knurled exterior for improved grip during installation and removal.

At approximately .635″ long, the compact design keeps your muzzle protected without adding unnecessary bulk. Multiple outside diameters are available to better match your barrel contour and create a cleaner, more finished appearance.
