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 black aluminum and is easily installed by screwing it into the objective lens. This model only fits the Primary Arms 3X prism scope and comes with a lifetime warranty. Optic in photo sold separately.

Great Kill Flash


This is an outstanding addition to the Gen III 3x Prism scope. It fits perfectly and only adds about 1/2 inch to the overall length of the scope. It is also compatible with the lens caps that come with the scope. The best thing about this is that it is virtually invisible in all light conditions and does not distort the amazing clarity of the scope. Exactly what you would expect from Primary Arms An ACOG quality scope for 1/4 the price!
