Height of Scope Mount Required

In each product catergory we state a maximum (upto) objective lens diameter dimension. Due to both rifle and scope designs varying this can only be used as a guide. If you are unsure that the height of the Sportsmatch scope mount you have chosen will be sufficient to clear your rifle scopes objective lens from the barrel of your rifle, we suggest (prior to purchase) you check. The way you calculate the clearance is by halving the overall outside diameter of your rifle scopes objective lens and then deducting half the rifle scopes body tube diameter. For scopes with a 1″ inch diameter body tube diameter this would mean deducting 12.7mm, 15mm for scopes with a 30mm diameter body tube and 17mm for 34mm scopes. This dimension then gives the figure comparible with the ‘A’ dimension that is shown below. The amount our ‘A’ dimension is greater than the figure you have calculated is the amount of clearance your scopes objective lens will be clear of your rifles barrel (dont forget to allow around 2mm for the scope covers). Calculating your rifle scopes clearance in this way does assume your dovetail or Picatinny rail is not raised above or below your rifles barrel. Please consider that rifles with grooved receivers such as some models of airgun and .22 rimfire rifle will mean the scope sits lower than a rifle with a raised dovetail or Picatinny base fitted. Something else to consider is that some rifles with a high or adjustable cheek pieces may require high or extra scope mounts so that your eye is in line with the rifle scope and your head is kept in an upright comfortable position.
