Anti-reflection devices have been used in military and police applications for many years to eliminating excess scope glare and hide any glint as to not give away your position. However, these devices have many more practical advantages for the everyday user. Eliminating scope glint can also be helpful in hunting situations as bright reflections can possibly scare away deer. It also is extremely helpful in keeping your glass clean from dirt and debris that can possibly scratch the lens. This anti-reflection device is made from anodized aluminum and is easily installed by screwing it into the objective lens. This model only fits the Primary Arms SLx 1X micro prism scope.

Works as expected

by -

Fit and finish is spot on with the optic. I primarily bought it for lens protection, appears it would knock out a reflection for anything that isn't directly in front. The honeycomb seems to be sufficiently deep enough. No complaints.

Works Well


I have this device on my PA SLx MicroPrism 1x. I am pleased with the performance. It does not impact the clarity of the sight picture and I would estimate that the overall impact on the brightness of the overall sight picture is a reduction of less than 5% of brightness and clarity, maybe 2% at most which is inconsequential. As for the claimed anti-reflection characteristics, it is totally effective with the elimination of all reflection. Highly recommended if you are looking for an effective almost perfectly clear anti-reflection device.

Great addition to the Micro Prism

Simple install and good fitment. Only slightly noticeable when looking through the optic but disappears naturally as your focus snaps to the target and reticle. Great addition to the Prism.

Sturdy, works
