TRUGLO TG8416B XR 21x16mm 3 MOA Red Dot Sight - Black

The TRUGLO TG8416B XR is a compact 3 MOA red dot sight built for shooters who demand precision without bulk. Whether you're running an RMSc-compatible optics-ready pistol or setting up a compact rifle platform, this sight delivers a clean, fast-acquisition dot in a footprint that doesn't slow you down. The 21×16mm objective lens is small enough to keep your sight picture uncluttered, yet the multi-coated optics maintain brightness and clarity across varied lighting conditions.

What sets the XR apart is the thoughtful engineering under the hood. The motion-sensing wake feature means your dot powers up the instant you move the gun—no fumbling with switches when time matters. Ten brightness levels let you dial in the perfect dot intensity for your environment, and the sight remembers your last setting, so you don't start from zero every time you power on. The CNC-machined aircraft-grade aluminum body shrugs off hard use, and unlimited eye relief means you can mount it however your rail space allows without worrying about your head position.

Field reliability is baked in: the IPX7 waterproof rating handles rain, dust, and spray without complaint. The auto-off feature kicks in after four minutes of inactivity, stretching battery life to over 20,000 hours on a single CR1632 cell (included). Windage and elevation adjustments are marked in 1-MOA increments, so dialing in your zero is straightforward. A Picatinny rail mount comes in the box, ready to go straight out of the bag.
