## Description

desertcart.com : Vortex Optics Defender-ST Micro Red Dot Sights (3 MOA) : Sports & Outdoors

Review: Excellent green dot - Outstanding sight. Dialed it in at the range then put 15 within a 3” bull at 10 yards no problem. Really nice quality and easy to attach.
Review: Very nice! - Perfect fit on my CA compliant Echelon 4.5. Only gripe I have is the adjustment tool is lousy, but the site itself is of hi quality and it retains its zero very well. It is absolutely worth the purchase.

## Features

- The Defender-ST micro red dot is as versatile as your interests. Built on a DeltaPoint Pro footprint with 12 brightness settings, this optic can be part of your EDC setup, mounted for turkey or run in competitions with the included picatinny rail mount.
- Featuring a larger window than the Defender-CCW, the Defender-ST has a hard coated, aspherical lens. It is the perfect size for a smooth draw and wide enough to quickly acquire the dot while providing a distortion-free sight picture and truer colors.
- Defender-ST automatically activates with motion, while the 10-minute auto-shutoff saves battery life. The motion activation only works when the unit is in sleep mode. Button lockout mode prevents unintentional setting changes.
- Using a CR2032 battery, the Defender-ST has greatly improved battery life over the Defender-CCW line. Although battery life varies based on user habits, the battery runtime with the red dot continuously active at setting 6 is 25,000 hours.
- The fast-rack textured front face adds grip for racking slide off of any surface. Waterproof, shockproof and with ArmorTek coating protecting the lens, the Defender-ST is ultra-durable. The ShockShield polymer insert protects against hard, daily abuse.
- Backed by our unlimited, unconditional, lifetime, VIP Warranty. A fully transferable promise to repair or replace your item if it becomes damaged/defective. Does not cover loss, theft, deliberate damage or cosmetic damage that doesn't hinder performance.
