Product Details
The Holosun 509T X2 is a solid enclosed red dot sight that works great on everything from carry guns to range shooters. You get a crisp 2 MOA dot for precise aiming, plus a 32 MOA circle if you need a wider target picture when things move fast. It's built tough with an anodized finish that handles the elements, and it comes with an adapter plate so it'll fit your gun whether you're upgrading from an RMR or starting fresh. The enclosed design keeps dust and debris out without the fuss of open emitter sights.
