At its price point the sight is well designed and engineered. - ADE Advanced Optics RD3-006B 1x26mm Mini Reflex Micro Sight

At its price point, this sight is well designed and engineered. It has a clear, bright green, MOA 3 dot display at all five brightness levels. The On/Off illumination control ("one button does all" ) is positioned on the front of the sight for one finger operation. Its controls are simple and easy to use, just keep remember, it does not have Auto Off function. Also, contrary to the product description, it will fit both picatinny and weaver rails. It come with a very basic manual, tools for adjustment, rubber sight cover and rail mount, but DOES NOT come with the CR2032 battery, which is stated, as part of the complete package, (see Description >Features & details>forth (4th) bullet remark, bottom of statement. "CR2032 battery included ") explaining why, I gave it only a 4 star rating.

IMPORTANT NOTE: As stated in the owners manual. It's very important to completely loosen the two small set screws, on the back of the sight, before adjusting elevation and windage screws! After you have finished making your adjustments, apply a type of "Blue Loctite" on the both set screws and tighten firmly. (not not over tighten)
