SWAMP DEER OPTICS Red Dot Sight, 1x34 Holographic Sight, 3 Pattern Red Dot, Compatible with 20mm Rails, Waterproof, Fogproof, and Impact Resistant,

1. This is the SWAMP DEER OPTICS HD511A 1x34 red dot sight. The large 34mm multi-coated lens provides exceptional clarity and an incredibly wide field of view. 2. The red dot with a 35MOA circle and a 2MOA center dot can be switched between three patterns: [Circle & Center Dot], [Circle Only], and [Center Dot Only], making it useful at an overwhelmingly wide range of distances, and useful for quick targeting at close range as well as medium range. 3. The CR2032 battery provides a 20,000-hour burn time in Dot & Circle mode, and it can also be solar-powered, making it the most complete red dot sight in SWAMP DEER's history. 4. Its dust and water resistance is an incredible IP78 rating, with dustproof level 7 and waterproof level 8, meaning it is completely dustproof and unaffected even when continuously submerged in water. 5. The body is a little heavy at 200g, but it is made of one-piece aircraft-grade aluminum with a hard anodized finish, making it extremely rigid.
