Upgrade Your Suppressor with a Silent Steel FlowComp Muzzle Brake 

You can purchase the FlowComp separately, and we can even install it on your suppressor before shipping!

How to order:

• Add your Silent Steel suppressor to the shopping cart.
• Add the Silent Steel FlowComp Suppressor Muzzle Brake to the same order. Select the correct caliber – the FlowComp Muzzle Brake caliber must match your suppressor's caliber.
• If you would like us to install the FlowComp Muzzle Brake on your suppressor, simply write "Please install the FlowComp Muzzle Brake" in the order comments at checkout.

Good to know: If you request installation, we will mount the FlowComp Muzzle Brake on your suppressor before shipping. The suppressor's original front cap will also be included in your package, so you can switch back to the original configuration whenever you like.

We recommend that the FlowComp is installed by a qualified professional. Damage caused by improper installation, removal, modification or handling may not be covered by the warranty or eligible for repair or replacement at our expense. Each claim will be assessed individually.
