Forward Controls Design - Thread proctor for 0.900 x 24 muzzle devices, no wrench flats - TPM

The Forward Controls Design TPM Thread Protector is designed to protect the exposed 0.900x24 external threads on compatible suppressor-mount muzzle devices when a suppressor or adapter is not installed. Its smooth exterior profile eliminates wrench flats for a clean, low-profile appearance while helping shield the threads from impact, debris, and handling damage. The TPM is intended for compatible FCD muzzle devices that use the 0.900x24 mounting interface, including Plan B and Rearden Atlas-style setups. Compact and easy to install by hand, the TPM provides a simple way to protect the mounting surface during transport, storage, or unsuppressed use. Its smooth, wrench-flat-free exterior ensures a streamlined look and reduces snag points. The FCD TPM is a practical accessory for preserving thread condition and ensuring reliable suppressor-mount fitment over time. By shielding threads from damage and debris, it helps maintain the integrity and longevity of your muzzle device's mounting surface.
