With the widespread popularity of 1.93” red dots and risers, Primary Arms Optics is proud to introduce the SLx® Flip-to-Side 1.93” Spacer Riser.

Made specifically for the SLx ‘FTSM’ magnifier mount (SKU: PA-SLX-FTSM), this spacer will bring the centerline of your magnifier to a 1.93” height. This riser is precision machined from durable 6061-T6 Aluminum and features the same style of hardcoat anodization to match your existing FTSM mount. It installs just like your regular magnifier spacer and includes all the necessary hardware for secure attachment.

This is a necessary component if you plan on running a magnifier and FTSM mount in conjunction with a 1.93” Red Dot sight or MicroPrism.

NOTE: This product was designed for the standard SLx Flip-to-Side Magnifier Mount (SKU: PA-SLX-FTSM). It also fits on our push-button magnifier mount (SKU: PA-SLX-FTSM-B) but will increase the centerline height slightly higher to 1.98”.

  • 6061-T6 Aluminum Construction
  • Hardcoat Anodized
  • Increases Magnifier Centerline to 1.93”
  • Designed for SLx Flip-to-Side Magnifier Mount (SKU: PA-SLX-FTSM)
