Thread: Gunwork incl. Barrel threading in Auckland

In that case a DPT wouldn't fit my rifle as it'll foul on the thread before it hit the shoulder.

All of our suppressors feature an internal thread relief of approximately 2.5mm in length. Occasionally, we encounter issues when muzzle threads lack a relief cut. These problems often arise due to the non-threaded section being excessively long or having a diameter larger than the threaded portion.
