Eotech XPS21 XPS2 1x 1 MOA Red Dot Black

Shortest model sight yet! This sight is smaller and lighter than the other HWS sights and runs on a single 123 battery. With the new single battery configuration the XPS allows more rail space than ever leaving more room for rear iron sights magnifiers or NV mount. Smaller lighter and always fast; the XPS series is a great compact option for your platform. - OPERATION - Optics: Transmission holography - parallax free - Magnification: 1x - Eye Relief: Unlimited - Length/Width/Height: 3.5x 2x 2.4 - Weight: 8oz (227 grams) - Temperature: -40 to 150 F - Waterproof: Submersible to 10 ft depth - Sealing: Fogproof internal optics - Adjustment (per click): 0.5 MOA (1/2 at 100 yds) - Adjustment Range: +/- 40 MOA travel - Mount: 1 Weaver or Picatinny (MIL-STD-1913) rail - Return to Zero: Repeatable to 2 MOA after re-mounting - Night Vision Comatibility: none - HEADS-UP DISPLAY WINDOW - Optical Surfaces: Anti-glare coating - Window Dimensions: 1.20 x 0.85 (30 x 23mm) - Front Window Material: 1/8 solid glass - Rear Window Material: Shatter resistant laminate (3/16 thick) - Field of View (100 yds): 30 yds (28m) at a 4 eye relief - ELECTRICAL - Brightness Adjustment Range: 146000:1 brightest to lowest - Power Source: (1) 123 lithium battery - Battery Life: 600 continuous hours at nominal setting 12 - Brightness Settings: 20 settings with scrolling feature - Auto Battery Check Indicator: Flashing reticle upon start-up - Auto Shut-down: At 8 hrs- programmable to 4 hrs
