Gunzilla is a terrific cleaner! I know that it says CLP, but I use Weaponshield as my LP as I believe it's more suited to that end of the equation. Gunzilla has a water-like consistancy, smells good, and really get's the dirt and fouling out. Take a quick test by pulling out one of your clean weapons and run a Gunzilla saturated patch down the barrel, you'll be surprised at how much comes out. I've taken "mirror clean" bores and found more in them. You don't really need much to clean either, so 4 or 16oz will be around for a while.

I chose both Gunzilla and Weaponshield because when I did searches on what soldiers use overseas both of these products came up over and over with rave reviews. If they are happy and asking their folks to send some over, it'll work for you at home or on the trail.

I agree with Mark Bennett. I've used both Gunzilla and Copperzilla (their copper cleaner) for a couple of years. Gunzilla does in fact do a good job of cleaning firearms and will take off light rust. BUT after the gun is left for several weeks with Gunzilla in the mechanism, it will start to gum up, and the gun must be cleaned up with another product. I use Break Free CLP for general cleaning and rust prevention, as does the military. Break Free, however, is not a very good cleaner for bores with copper deposits (see Copperzilla below). The good news is after a period of time Gunzilla will loosen rust in old guns like 75 year old Mausers, and make it easy to wipe it off. Another problem I've noticed is that Gunzilla will break down some modern plastic stock finishes like Remington uses on their new shotguns with wood stocks. It does not seem to harm the finish on oil-finished wood stocks. You will notice it makes some plastic finishes tacky very quickly and then dulls the finish by removing some of it. So, don't let it get on wood stocks with plastic finishes. For the same reason, however, Gunzilla does a very good job of cleaning plastic wad deposits out of shotgun barrels.

Copperzilla is another story. It is, in my opinion, the best bore cleaner out there to clean out copper deposits in gun bores. It is also very expensive, so I guess it should be. Just saturate a patch with Copperzilla, run it though the fouled bore, let it set for an hour, and you will be amazed at the copper, lead, and carbon deposits it takes out. I then wipe the bore clean with a dry patch, and run a patch saturated with Break Free through the bore for long-term storage. I also wipe down the gun exterior with Break Free. That combination seems to work very well, and prevents rust from forming during long-term storage. DO NOT get Copperzilla on aluminum pistol frames or nickel plating, and they warn of that on the bottle.

If Gunzilla were advertised as just a cleaner, I would give it 5 stars - it does a wonderful job as a safer cleaner, easily removing deposits that BreakFree CLP couldn't touch, and I have no adverse reaction to either skin exposure or the vapors. Unlike Hoppe's Elite Cleaner/MPro 7 cleaner (the primary competition among "safe" gun cleaners), Gunzilla is not water-based and won't promote internal rust if traces are left inside mechanisms. Great cleaner, and worth it on that count alone.

From my own use, Gunzilla appears to be ineffective as a lubricant/protectant. Initially, Gunzilla lubricated well, but after shooting a couple dozen rounds at an indoor range in semiautomatics, the guns started to have problems feeding and surfaces no longer appeared to have any lubrication at all to the touch (the slides feel bone-dry). Revolvers functioned flawlessly with Gunzilla and appear to have plenty of lubrication remaining after use.

Note that in the "lubrication test" on Gunzilla's own website, they only fired 25 rounds in total immediately after lubrication. Competing gun lubrication products are tested to successfully fire hundreds of rounds in highly adverse conditions. Gunzilla simply cannot hold up as a lubricant, so use something else after cleaning with Gunzilla.

Revolvers may be an exception where Gunzilla might be sufficient, since revolvers aren't as hard on lubricants as semiautomatics.

So I give Gunzilla -1 stars for claiming to be a lubricant, because people who believe that claim and act on it may subject their firearms to unnecessary wear.

Note that Gunzilla WILL attack some cheap plastics like PVC, but not most of those used in guns these days (supposed to be safe for polymer frames). Gunzilla damaged a cheap plastic-handle screwdriver that I used on one of my guns. Not a big concern, just something to be aware of.

This product performs the opposite way of what you want. After a period the solvent becomes very gummy and clogs the firing mechanism. My shotgun misfired several times prior to the deer season. I inspected the gun and you could see the build up of tarnish left by this product from previous cleanings. I proceeded to clean the gun as best I could to remove any remnants of Gunzilla. Thinking that I had solved the problem I headed out for the season. After hours hunting I finally saw a deer and when I pulled the trigger nothing, I loaded another shell, same thing. Finally, the gun fired on my third try and was able harvest the deer. I took the gun to my local gunsmith and told him that the gun needed a new firing pin. Several weeks later the gunsmith called and said "whatever you are using to clean this gun stop." I spent $50.00 getting the gun cleaned and now it works fine. My friends who also used this product experienced the same problems.

Great product, the only thing I have an issue I have, is the amount sold to me. In the picture of the product it showed a
16 oz. bottle and a 5 oz. bottle what I received was one 4oz. bottle. No where in the add did it say it was only 4 oz.
I guess buyer beware.

I am using this on my AR, it cleaned up easier than the products I have used in the past, the claim about being good on toast might be a bit of a stretch. It is my product of choice for the AR Platform.

Very good CLP. No harsh smell, easy wipe down and really does what it clams to do.
I will use this product on all of my firearms.
