Thx for replies. I understand about oil attracting debris, but I'm fanatical about cleaning my equipment.
You should see how I clean and pack my camping equipment. My wife says if I could only take as much care with my dirty clothes...lol
I see no irregularities on mag housing, so Id be suprised about hard cosmoline, but I will boil and follow up.
What kind of dry lube do you use?
Again, thanks for your time.
