I know that ya'll are getting tired of my newbie questions but I just noticed that my new to me 99H HP must have the wrong rear sight or ramp or both. The problem is that there is no room to to raise elevation by sliding the ramp back. The ramp makes contact with the receiver. What do you guys think?
