So I was sighting in my m14 at 100 feet. I have my windage adjusted right, but for my elevation I am still 3 mil dots high. Dots over the cross hairs. Hop up is all the way down and I am using ASGI .30's. I am using 44mm objective weaver rings which make my 50mm objective lens sit right on top of the heat shield.
Anyone have any suggestions as to why its shooting high?
Yea, check the bucking. My friend's KWA M4 was shooting high and it turned out to be that the bucking didn't seat itself properly into the hop-up chamber. It folded itself in and was pressing pretty hard onto the BB.
