Ruggedized red dot sight and compact design makes it pistol compatible but also able to tolerate heavy recoil for use on shotguns and rifles. 2 MOA dot, Wide Field of view, Waterproof, Fog Proof, Recoil Proof with additional NV settings. 

From Blake: “The DPP is my red dot of choice, the larger window works great with my eyes. Dot is bright and crisp and allows me to engage steel at long distance and also snap between targets in extremis.”
