Primary Arms
Overview
The Primary Arms SLx 1-10x28mm SFP Rifle Scope is a versatile low-power variable optic (LPVO) designed for both close-quarters and mid-range shooting. With a magnification range of 1X to 10X and a second focal plane reticle, this scope allows builders to engage targets effectively at varying distances while maintaining a consistent reticle size. The illuminated BDC reticle in red enhances visibility in low-light conditions, and the scope's total adjustment for windage and elevation is 40 MOA, offering plenty of flexibility for precise zeroing. This scope is commonly found in builds chambered for 5.56 NATO, making it a solid choice for those looking to optimize their performance across a range of scenarios.
