Meet the Alpha Series from Monstrum - a new line of first focal plane rifle scopes for shooters that want reliable FFP optics without the electronic features. The full multi-coated lens reduces glare and resists scratching while improving light transmission and sharpness. Fully Sealed, nitrogen-filled tube is weather resistant and fog-proof. Manufactured with the same components as our top selling G3 line of FFP scopes.
FFP stands for First Focal Plane. The term refers to the position of the scope reticle in relation to the magnification lens. In FFP scopes, the reticle is located to the front of the magnification lens - the first focal plane. The size of the reticle grows or shrinks in relation to the magnification.
In SFP (Second Focal Plane) scopes, the size of the reticle is fixed regardless of magnification. Unlike First Focal Plane scopes where the size of the reticle changes. Range and distance information on the reticle remain constant in an FFP scope regardless of magnification - so a 1 MOA hashmark is equal to 1 MOA at all levels. Tasks such as range estimation, hold over correction, and bullet drop adjustment can therefore be performed much more easily.
