I took my new AIM BCG to the range yesterday and ran about 100rds through it at the range. Once I came home and popped it out to clean this is how I find it…even after cleaning it with hoppes #9 and taking a toothbrush to it the discolorization will not come off. I bought this for ease of cleaning and while I do not believe this hinders the performance, is this normal? More or less a pain in the ass, especially when I clean it the next time I’m gonna keep thinking it has buildup. I watched mrgunsngear’s video review when he breaks down the BCG and it looks nothing like this, looks as clean as when it came out of the box.
Other info- I’m running this through an Vltor MUR 1A, I was using 55g .223 ammo from PPU Ammunition, light lube before using.
Hhhmmmm that would have been good to know, wouldn’t have thought that. The label says do not “soak” nickel plated. Which I dipped a toothbrush in and lightly scrubbed no soaking.
Fail Zero and a few other companies specifically say not to use Hopps #9 on it. If there is a warning on the bottle about nickel, you should avoid using it.
Reason I just use Rand CLP and fireclean. 0 crap that will mess coatings up.
Question is, did it look like this before or after you used the Hopps. Either way tho, I’d discontinue using it right away regardless of if this caused it.
Was it like that when you received it? Sometimes manufacturers will use copper (II) sulfate to test the quality of their nickel plate. They will pull out a specimen and immerse it in the copper (II) sulfate. This could have been one of their test pieces.

Well the bottle only said dont soak and of course I didn’t look at the bottle until after I posed this thread. I just got complacent using hoppes. On a side note this is the first BCG with an o ring for the bolt that I’ve owned. From what I’m reading you don’t have to have it. B/c it’s a pain in the ass, I can’t get the bolt pin back In Without needing some channel locks. So I just left it off and the pin feed right through.
Slight derail. Will Hoppes 9 discolor a straight nickle plated finish? Had an old Nickleplated revolver that was given to me a number of year back by a friend of the family after her husband died. Shot it about 15 times, could care less about it but I have never see any discoloration and Hoppes is my usually choice for cleaner. All this is making me want to pull it apart and see if there are any stains on it. Of course I’ve never soaked it in the Hoppes either. Could the NiB coatings be more sensitive to this type of thing?
