Rifle scope
RBP Mountain Shooting Course
A riflescope used for extended range shooting has numerous requirements. A high quality riflescope is imperative to successful application of the dope required to hit at extended range.
Erector Tube This the main body of the scope. In the scopes we usually use comes in 30,34 or 35mm’s. The larger tube dimension allows for more elevation adjustment. This is what dimension your scope rings are for.
ocular lens This is the lens closest to the eye. This is where your reticle focus is adjusted. This traditionally has to be done to match your vision only one time. Many scopes have a lock ring once this is properly set. Some scopes have better engineered Ocular lens’ than others and are easier to properly get oriented with in shooting position. This is what is referred to as a generous eye box.
Objective Lens This is the lens towards the muzzle of the gun. The scopes that we use typically have at least a 44mm objective lens and go up to 52mm or greater.
