was hoping someone out there could help me out with a query, I've got a set of second hand schmidt and bender 8x56 scopes that Im going to try out this weekend and was wondering if anyone knew much about the following:
1. on the windage turret there is a small screw labeled L-M-R, covered by flexible plastic, can you tell me how this effects the zero point/the main windage, is is simply a more refined adjustment?
2. As its covered with plastic how would I adjust this? I dont want to remove the film incase its some waterproofing function.
Thanks in advance and apologies if this is a really obvious one, i've a feeling it is!
