I dropped my gun and sumtoy mount off at gunsmith this morning for D/T. Once I get it back, I will be adding my SF kingslayer. The mounting screws that come with the sight do not appear to be overly long to me. Do most of you just use the screws that come with your sights or do you add longer screws when mounting? I think the screws that come with the sight are 6-32x.315L. I think I have room for .500L(maybe longer) with the sumtoy mount but unsure if the add'l length is worth it.
