I noticed Knight has this on sale for $25. And was wondering if their claims were true with the crud ring issue.

• Hardest Clear Coat in the firearms industry
• Superior corrosion protection
• Does not affect velocity, accuracy, or group size
• Eliminates crud ring caused by powder

it helps reduce the crud ring, doesnt get rid of it completely. The biggest plus with that product for me is the fact i do not have to worry about my bore rusting up in foul weather.

I have no complaints at all. The crud ring is reduced big time.
