The Boltlok system eliminates one of the most common problems with silencers: ensuring reliable mounting even during sustained fire. Even when the silencer is fired under extreme heat, the locking mechanism remains fully functional.

• The silencer does not come loose under intense firing stress
• The locking system does not jam or seize up when exposed to heat
• Secure attachment even under high operational stress

The Silent Steel Boltlok system is fully compatible with existing Borelock muzzle devices. This allows for an upgrade without having to change the existing configuration.

In addition, the Boltlok system will be available across the entire Silent Steel product line in the future—for both silencers and future accessories.
