The Aimpoint® Acro P-2 is the next generation in the Acro series with an optimized technology. With the new battery size of CR2032 and new diode technology the Acro P-2  will last for 5 years of continuous use on setting 6/10 (daylight setting) . The new design of the Acro P-2 makes the system submersible to 35 meters (115 feet). The new LED gives you a brighter 3.5 MOA dot.
The Trijicon RCR is a rugged closed emitter optic designed to meet the needs of Law Enforcement professionals and military applications. The RCR is designed and built to withstand the harshest environments and features durable 7075 T6 aluminum construction with a hardcoat anodized black finish. This optic features a top-loaded battery, tru-color multi-coated lens, over 6 years of continuous use, and a Super Strong Patented Capstan Screw.
With long-requested enhancements, the new Trijicon RMR HD takes the iconic RMR to new heights. Compared to the original RMR, the RMR HD features larger, more responsive buttons, an expansive window with a large field of view, and a complex reticle that allows users to choose between a simple 3.25 MOA red dot and a circle dot reticle.
The Trijicon RMR Type 2 was designed to improve the speed and accuracy of nearly any small arms weapon platform. Incredibly lightweight, the Ruggedized Miniature Reflex sight provides a simplified and open sight picture, allowing the shooter to simply place the red dot on the target rather than focusing on aligning iron sights
If you are looking for a durable mini reflex sight to mount on a pistol for competition use or even concealed carry, why not make the same choice as US Special Operations Command (better known as USSOCOM) has selected through their Handgun Reflex Sight program? With a patented aluminum housing design that protects the lens from impacts and upgraded electronics, this red dot sight can withstand the harsh recoil of a pistol slide for thousands of rounds without failing.
