Bolt cleaning tools

[montana]

Be careful with any scraper. They can reduce the bolt tail diameter over time causing unnecessary gas leakage in the firing pin chamber of the bolt carrier. I never scrape anything on my bolt carrier or bolt. Solvent, tooth brush, cleaning patch and Q tip or "cotton swabs" https://www.brownells.com/gun-cleaning-c...13150.aspx is all I use. For neglected carbon build up, break cleaner works great. It is easy to scratch up the chrome surface of the gas ring chamber if not careful.
