RE: KRB7 trigger group
I use brake cleaner to blow it out. Any small crevasses I hit with an old tooth brush. It really justtakes a few minutes to clean. I let it dry then spray it with rem oil. Blow back into theaction assemblyisn't too bad, around a 5 maybe a little less. No more or less than what I was getting with my CVA optima.As far as primers, I've used 777 primers and standard winchester primer with good results.
