The SLx FS 3x Magnifier supplements your red dot or 1x prism with added magnification when engaging targets at medium to long distance. This magnifier is part of our SLx optics line. SLx optics built our reputation for innovation, reliability and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.

Compatible with the most popular mounts on the market, the SLx FS 3x Magnifier is a versatile addition to any close-quarters optics setup, and the enhanced glass quality and wide field-of-view ensure that the user can always get a clear view of their target. Though the SLx FS 3x Magnifier weighs a mere 8.45oz, its durable construction protects it against the repeated shocks and impacts of duty use.

As with all other Primary Arms Optics products, this magnifier comes backed with a limited lifetime warranty and commitment to customer satisfaction.
