**IMPORTANT!! READ BELOW**

This program is to update your Revolution Silencer to the current housing. To complete this transaction, you will need to purchase this upgrade, review your manual for the part listed as "Booster Housing" to send in, and a copy of your Form 4. ONLY SEND IN YOUR BOOSTER HOUSING PART, NOT YOUR SILENCER TUBE BODY. Failure to follow these steps will result in cancellation of your order.



Once you have placed your order, mail your Booster Housing, copy of Form 4 and a copy of your order invoice to:



Griffin Armament

P.O. Box 230

Watertown, WI 53094





When you send in your Booster Housing, you will receive the new Booster Housing, new piston housing, and the new Rev Wrench.



YOU DO NOT NEED THIS UPGRADE IF YOU HAVE OR ARE PURCHASING A REVOLUTION GEN 2 (or later) OR RESISTANCE SILENCER. THIS IS FOR REVOLUTION GEN 1 USER. This comes with Gen 2 and on.



If you do not want to separate your External Booster Housing and Piston Housing, you may send both in, however, your old parts are not returned.
