Silent Steel suppressors have a variety of mounting options for specific needs.

Boltlok Mount (QDB) to Silent Steel QDB muzzle devices

Silent Steel is excited to introduce its latest patent-pending innovation in suppressor mounting technology: the Boltlok™ Quick-Attach System.

The Boltlok QD mount offers a user-friendly, secure, and stable solution for suppressor attachment. Engineered to remain exceptionally lightweight, it adds minimal weight compared to traditional direct-thread suppressors.

During initial installation, users can adjust the locking tension for the tightest possible fit. The Bolt mechanism provides six positive positions, allowing shooters to select the optimal setting on first use. Once adjusted, operating the system is quick and straightforward: simply attach the suppressor and slide the locking latch fully rearward to achieve a secure, repeatable lock-up.

This mechanical quick detach locking system is compatible with all Silent Steel muzzle devices with some exceptions.

Engineered for strength and durability, the QD Lock Mount is designed to perform flawlessly even under extreme conditions.QD Lock Mount will not seize when it gets hot, ensuring reliability when you need it most. It’s incredibly easy to use, offering constant locking without any point of impact (POI) change. The system is completely closed, eliminating gaps and openings where mud and dirt could enter the locking mechanism. Additionally, the taper at the front of the muzzle device seals the locking mechanism from the suppressor, preventing fouling.

Universal suppressor HUB mount
Silent Steel universal hub is a direct thread adapter for third party suppressor mounting solutions. The suppressor thread is standard 1.375″×24 or 1 3/8″×24 which can be used as a base for different mounting systems.

The benefits of universally threaded suppressors are that they are no longer tied to a specific company’s mounting system and they can be configured in different ways depending on the use case. In the past, if you had your firearms setup for use with a specific company’s muzzle device, you couldn’t use another company’s suppressor on that firearm.
