The Primary Arms SLx family of optics is a budget-friendly lineup that features various types of riflescopes and electronic red-dot sights and other aiming devices. Now Primary Arms Optics is releasing a new addition to their SLx product line, a 1-10 power LPVO (low power variable optic), which features a 1-10x28mm SFP (second-focal-plane) reticle. 

“As LPVO technology gets better and better, the optics become more and more versatile,” says Stephen Morgan, Product Marketing Director for Primary Arms Optics. “We have developed our new SLx 1-10 with the do-all, universal rifle in mind. Fast and wide at 1x and ultimate precision at 10x, it is the perfect fit for your next do all rifle build at an affordable price.”

  • 1-10 Power zoom range
  • 28 mm Objective lens
  • 6061-T6 aluminum 34 mm main tube diameter with black anodizing
  • 10 ½  inch overall length and 19 ounce overall weight

This new scope, like the other products in Primary Arms’ SLx optics line, combines quality construction with robust set of features, yet still at a budget-friendly price. Trained Primary Arms Optics staff personally inspect each riflescope for quality and performance at their Houston, TX, headquarters, and every optic in the SLx line also comes with Primary Arms Optics’ comprehensive lifetime warranty.
