This is in regards to my RUGER AMERICAN Predator. I sent Ruger customer service this following message: "Hello: My new Ruger rifle seems to have a weak finish on the receiver. It seems to wear off from just using gun oil, clean cleaning patches and a nylon toothbrush-type gun brush. There are bare (white) metal spots inside the "C" of AMERICAN most predominantly. A few other areas of this receiver are spotty where bare metal shows. This receiver looks matte black. What material is the finish specifically? Is the exterior metal black finish covered under warranty from premature abnormal wearing off as from normal cleaning? This gun has not even been fired once yet. I gave the gun its initial cleaning according to the manual and noticed that the finish is looking spotty on the left-side of the receiver where RUGER AMERICAN is stamped." I sent a message here the other day about this same rifle. It takes vigor to chamber a round and close the bolt. Also there is a loose piece screwed onto the end of the barrel." I bought this Predator at my local Academy not long ago. The other Predator that was in the store on display had much worse cosmetic spottiness on the receiver and I thought it might have been from just rough handling of the gun. My new Ruger American Ranch rifle has much nicer and more durable finish on the receiver and normal cleaning methods did not harm the finish one bit. The Predator rifle might have been built on a Monday or a Friday while the Ranch rifle might have been built on any other work day. I still like the paramilitary-style black (or gunmetal gray) finishes on Colt AR-15s, army M16s and Remington 870s (I own such a Remmy) much better. These new matte black finishes so common on today's sporting guns seem to have a powdery/gritty feel and cleaning patches and silicone gun cloths rubbed over them seem to feel very sticky. Cloths leave lot of lint on these fine-grit sandpaper-like matte gun finishes. When rubbing a coat of gun oil over this type of finish to beautify it, it seems to have a mottled look. I have to massage the oil into the finish with a nylon toothbrush to "groom" it so the finish looks even and smooth in sheen and color. Likewise, I used the military toothbrush to groom the barrels and receivers in the army for my M16s to make them look pretty. CLP works real nice on M16 finishes, however and those finishes are rather slick on the surface and not gritty. The toothbrush also removes cloth lint and debris from any stampings in the metal. Rubbing alcohol seems to clean any gunk (including CLP) off these finishes quite nicely. Break-Free CLP seems to gum up these "friction" finishes badly. This type finish shows fingerprints really easily when handled. I prefer slick traditional blue finishes over these new matte black finishes but I can make black matte look neat by buffing it with a toothbrush after using cloths and a light coat of oil. The finish on my new Predator seems to be inferior in durability to the finish on my new Ranch still. Rubbing cleaning patches over the matte black metal on my two new Ruger Americans leaves a yellow residue on the patches. Ruger must put some preservative on them. Rubbing alcohol on clean white patches seems to remove this gunk nicely.
