Finally picked an ultrasonic cleaner after saying I was going to for months. I cleaned my BCG to see how it worked. Just using water with a little dish soap for now. The carrier had about 120 rounds since last cleaning and when I clean I'm really anal so it was spotless when I started.
This cleaner is awesome and saves me a ton of time.
on to the pics.
out of the gun
hosed it with powder blast then took it apart
Bolt face
after 480 second cycle. Still some carbon on the bolt behind the gas rings.
After a second 480s cycle
Cleaned bolt face
closer pic of the bolt. I scraped the rest of the carbon off in about 10 seconds.
You can see where chunks of carbon came off inside the bolt carrier too. No pics of that.
