Overview
The Primary Arms SLx 3-18x50 is a variable magnification riflescope designed with a first focal plane (FFP) reticle that maintains scale across all magnification levels, allowing for accurate holdovers and ranging at any zoom. With a magnification range from 3x to 18x and a large 50mm objective diameter, this scope provides excellent light transmission and clarity, making it suitable for both short and long-range shooting. The illuminated BDC reticle enhances visibility in low-light conditions, making it a solid choice for precision builds commonly used in tactical or hunting applications.
