Red-dot EOTech HWS 512 – Black / 1-Dot Speed Ring

Product detailed description

Professional opinion:

I really like the 512 for sporting use. Why?

• Because it is simple and reliable.
• It sits lower—but with low-profile Sordin hearing protection that is OK, and with a proper cheek weld your eye lands directly on the dot instead of searching for it like a needle in a haystack.
• In an emergency, the first shooter next to you or almost anyone nearby can give you ordinary AA batteries, or you can pull them from another device. 
• If you also remove the aluminum hood, you improve the view around the sight window, and it is great.
• For me, it is a top choice for sport and ordinary civilian shooters.
• I use it myself when shooting IPSC Rifle Open at smaller matches where an LPVO is not needed.
