Bore Tech’s PROOF-POSITIVE JAGS is a revolutionary product in the field of ‘pushing pecks’. They allow you to eliminate the annoying incrustations of copper from your holes caused by traditional brass jags. Using a special alloy patented by us and a process based on specific secondary treatments, the new “push-pieces” of the Proof-Positive series are characterized by the following innovations:
1) 100% preserve the integrity of the cane
2) 100% resistant to chemicals
3) are 100% free from any type of fat
4) are 100% heavy-duty
Save your gun and your barrel from the harsh treatment and damage that are typical of galvanized steel and stainless steel jags. Free yourself at low prices of the fragile and frustrating plastic jags that fold and break. Traditional brass jags contain over 60% copper in their composition, resulting in the formation of blue copper on your piece even when copper is not present in the hole you are cleaning. Eliminating the brass can be effectively determined when the rifle hole is truly without copper residues, thus reducing wastage of cloths and cleaning time.
