So I have This Scope and im looking for flip up covers. I measured (roughly) the diameter of the housing of the objective and eyepiece lenses. eye piece is 43mm obj is 55mm. I was looking at These covers and im not sure if they wouuld fit or not since the eyepiece measured around 43mm. but as i said those are rough measurements. I couldnt find my calipers and had to use a ruler and so those are rough measurements. im thinking maybe the eye piece is ACTUALLY 44mm and my measurement was off a bit. Does anyone have the Hammers 4-12x40 and know what size flip ups i need? TIA.
