Hello, I have an 03a4 that is all correct GI, but decided to use for deer/bear hunting an want to sight her in. It seem's the windage screws on rear base/ring gross alignment is starting to strip or ready to shear off(can't tighten down solid). I think I need new GI windage screws!?!?!?.......anybody have a couple to sell??? also, what did GI's do when bad weather to stop rain from messin with scope lenses??...........thank.....sonny
