I bought myself an hha slider 5019 for Xmas and went to sight it in today. Left and right was good, but the slider is almost all the way up at 20 yards. In other words the sight housing will barely go any lower. The housing is screwed in as low as it can be. Will moving my peep up help at all? I'd hate to have this sight and only be able to shoot like 35 yards with it.
