Seal 1 SCL4 Signature Copper and Lead Remover Against Copper Build Up, Fouling 4 oz Jar

Copper and lead fouling builds up fast in rifle barrels, degrading accuracy and requiring more aggressive cleaning down the line. Seal 1 SCL4 Signature Remover tackles that buildup before it becomes a problem. Whether you're running suppressed or shooting high-volume practice sessions near San Jose, this 4 oz jar dissolves fouling efficiently. TacticCAL Gun Store, your FFL dealer in Silicon Valley, stocks this proven cleaner for shooters who maintain their rifles seriously.

Dissolves fouling without excessive scrubbing

Copper and lead deposits restrict bore diameter and throw shots off target. Seal 1 SCL4 works by chemical action rather than abrasion alone, cutting cleaning time on heavily fouled barrels. A 4 oz jar lasts through multiple cleaning cycles depending on your shooting volume and barrel condition. Apply, soak, and wipe—no need for aggressive brush work that can damage rifling. Shooters handling private party transfer process paperwork appreciate having quality solvents on hand before taking possession of used rifles. Browse our firearms dealer.

Frequently asked questions

How long should I let SCL4 soak in the barrel?

Soak time depends on fouling severity. Light fouling typically requires 15–30 minutes; heavy buildup may need several hours or overnight. Follow the manufacturer's guidance on the jar label for best results with your specific barrel condition.

Is SCL4 safe for stainless steel barrels?

Yes. Seal 1 formulations are designed for standard rifle barrel materials. Always rinse thoroughly with solvent and dry completely after use to prevent any residue from sitting inside the bore.
