I finished browning my lock parts, gave them a bath in ammonia to neutralize, heated the parts and applied motor oil to them. I checked them the next day and the parts were still rusting bigtime.
I stripped them of the oil and gave them another ammonia bath, all day this time. Again I followed the ammonia with a soap and water scrub, more heat and motor oil.
The last time I followed this procedure my parts stopped rusting immediately. I did have a barrel that kept rusting for a month or so in spite of plenty of ammonia and baking soda treatments so I know these parts will stop rusting in time.
I want to assemble the lock as my rifle is almost finished but won't if I have to keep carding rust off the parts.
