Thread Adapter | Silent Steel Sig M13,5x1LH

Certain gun manufacturers use non-standard threads in their barrels, which can be problematic because these threads will not accept muzzle devices designed for barrel threads with a 90-degree shoulder behind the thread.

To address this issue, Silent Steel is manufacturing thread adapters which allows you to use standard muzzle devices on non-standard barrels, providing a seamless solution to the compatibility problem.
