4 Different Reticle Options

Adjust between a 10 brightness settings and two color options (red & green) at the touch of a button.

Longer Battery Life

Powered by a single CR123A battery, the R-Spec reflex sight has the ability to run up to 2,000 hours.

Low Battery Indication

– 2 hour low battery indication-each press of a button the reticle will blink four times.

– 10 minute low battery indication-the reticle will continuously blink until a new battery is installed.

Flush QD Mount

The new quick detach mount for the R-Spec and A-Spec is designed with a low profile. Now the handle sits nearly flush with the main housing. The low profile design eliminates snags on vests or other equipment. With this design, the handle remains set in the open position due to the flat cut near the handle’s axis of rotation. This small improvement keeps the handle stable and not loose potentially marking the finish. Finally, the handle is made of steel noted by it’s different finish. Steel is more durable and less prone to breaking.

InterlokTM Adjustment System

The interlok adjustment system is a internal retention system that ensure windage and elevation adjustments remain zeroed during recoil. Competitor reflex sights typically require the adjustment system be unlocked. The interlok adjustment system removes the need of a locking mechanism so users can make adjustments on the fly.
