Basically every day in the summer before bed I have to brush them off real good and reapply a light coat of oil. It got old at first but truly I have gotten into the habit now and while doing this I just do a whole rundown of the gun with a oiled rag inside and out. Then brush the sights and Lube them last. In the summer the gun just attracts so much dirt it's just like a daily PMCS for it.I love my dawson sights, but the rear sight rust like crazy. I imagine I'm not the only one with this problem. What are yall doing to keep the rust off?
