Taper at the front of the thread ensures solid lock up and minimal/repeatable POI shift and it also effectively blocks fouling from entering the mounting surfaces.

Boltlok Protective Cover
The Silent Steel Boltlok Protective Cover is a 3D-printable protective cap designed for Boltlok-compatible flash hiders and muzzle devices when the suppressor is not installed.
The cover helps protect both the mounting threads and Boltlok locking teeth from dirt, debris, impacts and other external damage during transport, storage and everyday use.
By covering the exposed mounting surfaces, the Boltlok Protective Cover helps keep the critical attachment areas clean and protected, ensuring that the suppressor can be installed smoothly when needed.
Print It Your Way
The Boltlok Protective Cover is designed to be 3D printed from plastic, making it a simple, lightweight and easily replaceable accessory.
Users can choose the material and color of the cover to suit their own setup. The cover can be printed in a single color or, with a compatible 3D printer, in multiple colors to match or complement the color scheme of the firearm and equipment.
This also makes it easy to create different color combinations for identification, personalization or simply to match the overall appearance of the weapon system.
The 3D model is available as a free download from the Silent Steel website, allowing users to print additional or replacement covers whenever required.
