## Description

desertcart.com : HOLOSUN HE515CT-GR Multi-Reticle Green 2 MOA Dot & 65 MOA Circle Micro Sight for Rifles - Solar FailSafe Shake-Awake Dustproof Waterproof Titanium Sight with Multilayer Reflective Glass … : Sports & Outdoors

Review: Best features on a red dot. - Great optics. You cannot find features like these on any other red dots on the market. Solar, shake awake, multi reticle, amazing battery life, and titanium body. Only thing I wish they would improve is the battery tray. Small tray with tiny torx screws is not an ideal solution. Would much prefer a tooless battery cover. Luckily the battery lasts so long that you rarely have to deal with the tray.
Review: Works - Great except for the big circle looks slightly doubled like there is another circle overlapping

### ⭐ Item received DOA
*by M***N on March 31, 2019*
