Is it a good or bad idea to use products like Sweet's 7.62 solvent with ammonia in them to clean chrome lined barrels.Or is the ammonia going to damage the barrel.

If ammonia is the active ingredient, it'll do no more harm to your chrome-lined barrel than polishing your bumper with Windex will do.

Try this.

Once you do you will throw out, or give away all of your ammonia based copper removers. This stuff is that good. It actually contains rust inhibitors. Bill T.

My favorite cleaner is CLP the military rifle cleaner seems to work ok for me but you should be ok to use that without barrel damage.

I really doubt you'll have much of any copper fouling in a chrome lined barrel. I did use CLP in my chrome moly DPMS barrel during break in, soaked the head of my bore snake in it and ran it through a couple of times for cleaning. Seemed to work out okay.

Had someone tell me that the ammonium etches the chrome giving the same blue residue that copper fouling does.Sounds like he didn't know what he was talking about so I'll just use Sweet's on the barrel and not worry about it ,but I'm curious about the other products thats been mentioned here so I'll also try those.Thanks for the responses.

I just use one part ammonia to two parts water. Takes out copper like crazy and doent cost a lot. I use it on chrome lined barrels as well.

I love using Barnes CR-10 for cleaning copper. I actually don't take the copper out on every clean, since it actually fills in the tooling imperfections. Only when I see it starting to degrade accuracy do I clean it out.

This might help.I have never heard of a quality copper solvent hurting a chrome barrel. ,,,sam.

Cleaning the AR15 - with its chrome lined barrel - is a little different than cleaning a regular sporting rifle. The chrome lining will take longer to break in - usually 100 - 200 rounds, and once properly broken in, will really not require much scrubbing until many thousand rounds later when your target groupings start to suffer. Chrome barrels don't get fouled nearly as quickly as steel barrels, and they won't rust or pit either. Here's the basic cleaning process - after a shooting session, clean the bore and chamber with a nitro solvent (Hoppe's or equivalent) and run patches through until all solvent is removed. Caution - any solvents that can affect nickel may damage the finish of the receiver unless removed. A Nickel Acetate sealant is applied as one of the receiver's last finishing steps, and some solvents will attack that finish. The use of a chamber rod guide (available in our catalog) will limit your cleanup. Once the rifle is clean and dry, apply a light oil with Teflon but don't over-do it. We sell the Tetra brand, others are Break-Free and Rem-Oil. The manual that comes with your rifle will show you how and where to oil. After many (thousands) of rounds, if the rifle's accuracy starts to suffer, scrubbing the bore down with a good copper solvent, plenty of elbow grease, and patience, will produce a barrel that shoots as good as new.
