UTG ACCU-SYNC 2521R Dot Sight Red 3.0 MOA Single Dot - OP-DS2521R

UTG OP-DS2521R: UTG ACCU-SYNC dot sights come in a compact and subcompact size and feature a red illuminated 3 MOA dot with 8 manually adjusted brightness intensity settings to choose from. Illumination memory conveniently gets users right back to the last brightness setting used upon activation. Fully sealed, ACCU-SYNC dot sights are IPX7 waterproof rated and constructed from matte black anodized 6061-T6 aluminum. Optimized for low power consumption and powered by a single CR2032 battery, a 30,000+ hour battery life (at middle brightness) comes standard.
The mounting base uses the common mini ACOG footprint and is configured for a lower 1/3 co-witness out of the box. Removing the included riser drops the height down to that of a low mount providing users two commonly used height profiles for different firearm applications. In addition, the base features squared recoil stops and our QR (quick release) mount, making for a quick installation and removal, reliable return to zero, and is compatible with Picatinny rails with widths that may even be out of spec. Tool-free tension adjustment is locked in place via a gear and spring-loaded locking lever interface, allowing users to set it once and forget it.
