Frequently Asked Questions

What makes the Silent Steel QDL suppressor system secure?

The QDL system enhances security by using fewer threads than older QD systems and incorporating an additional internal locking mechanism. This design ensures a more robust and reliable attachment of the suppressor to the muzzle device.

Why is the Silent Steel Compact Streamer QDL suppressor being discounted?

The Compact Streamer with QDL is 20% off because Silent Steel is discontinuing this specific system. They are introducing a new QDB system, and the current QDL muzzle devices will not be compatible with the new QDB suppressors.

What are the performance benefits of Silent Steel's Gen 3 suppressors?

Gen 3 suppressors from Silent Steel offer improved sound suppression capabilities. A key advantage is their design for almost zero back pressure, which helps maintain the firearm's original cycling characteristics and reduces gas blowback to the shooter.
