Removing the atomized matrix of carbon and lead fouling from suppressors is very hard to do, but is necessary to maintain proper functionality and protect the investment. The Suppressor Shield(TM) Suppressor Pre-Treat Kit, featuring our break-thru formulas (Carbon Destroyer XX(TM), Nothing Left(TM) & Accuracy Oil(TM)), is designed to PRE-TREAT "CLEAN" SUPPRESSORS (new or used) and MAKE FUTURE CLEANING SIGNIFICANTLY EASIER.
