Is it safe to use CLR for cleaning a nickel boron bcg? I have a number of BC's that are made of nickel boron and was wondering if the chemicals in CLR will harm any of the parts in it. IE - Firing pin, bolt, gas key etc.
 
Not sure, but I just use either shooters lube solvent or most frequently Boretech carbon eliminator. Just take BCG apart, apply, wait a couple of minutes and wipe or use a toothbrush, come clean pretty easy.
 
I'm beginning to think using CLR is a bad idea.

I have used CLR for cleaning titanium and 17/4 steel baffles on my suppressors and it works great. I break down the suppressors, put them in a glass canning jar full of CLR and let it go to town for a few days. I think it's pretty amazing how well it removes carbon, lead etc. from the baffles of a .22 can.
 
It's more so the bolt, cam pin, carrier key and interior of the bolt carrier (With the bolt removed) that I was looking for a short cut in cleaning...

Gotcha. Light use of the 2 Brownell scraper tools, a little bit of carbon remover, wipe dry, apply oil.

5 min max, goal is to remove 75-80% of the carbon and more importantly, apply lube where needed…

Lucasoil CLP has worked well on the nickel boron BCG I have.

No offense intended... but how clean does it need to be ?

I have never bothered to clean my NiB BCGs and parts more then a wipe down and relube.

BTW... what lube are you using ? I heard Hoppes is not meant for Nickel surfaces.... if that includes NiB , I do not know.
