The Rugged Suppressor FC004 Front Cap for .45 ACP is a drop-in replacement front cap designed for the Obsidian 45 suppressor. If you run a modular suppressor system and want faster configuration changes without breaking down your whole can, keeping a spare front cap on hand—or pre-mounted on your ADAPT Module—streamlines the process considerably. Whether you're swapping between rifle and pistol hosts or just want a quick second setup, this black-finished front cap lets you do it without the full teardown.

This is genuine Rugged Suppressor OEM hardware, so fitment is exact. The matte black finish matches standard Obsidian 45 aesthetics and holds up to regular handling and suppressor maintenance. It's a small piece, but in a modular system, having extras eliminates downtime.

If you own an Obsidian 45 and value speed and flexibility in your suppressor configurations, the FC004 front cap belongs in your parts bin or pre-assembled on a backup ADAPT Module.
