Pb Blocker was originally formulated to combat lead build up in the barrels of Glock pistols as this is a common problem shooting lead through stock Glock barrels which can result in catastrophic failure.   Pb Blocker helped nearly eliminate lead build up, which opens up the ability to shoot the less expensive lead through your Glock.   After extensive testing with extremely positive results, we soon discovered many additional applications reducing build up including lead, plastic, brass and copper with the same, excellent results.   The unique coating abilities of Pb Blocker virtually eliminates the extensive cleaning process. 


Simply put, Pb Blocker enables you to SHOOT MORE AND CLEAN LESS safely!
