Vortex Defender-ST Enclosed Solar – 3 MOA Micro Red Dot (DFST-MRD3-E)
An enclosed-emitter micro dot with a solar panel on top and a battery in the side: 3 MOA dot (plus a 32 MOA circle you can run with it), 7075 aluminum housing, DeltaPoint Pro footprint, 1.82 inches long and 1.62 ounces. Battery-only runtime is 35,000 hours at setting 6; with solar Vortex rates it up to 150,000 hours. SKU DFST-MRD3-E, UPC 843829142854.
Enclosed Housing and Solar
The emitter sits inside a fully enclosed 7075 aluminum housing, so debris and weather do not have a straight path to the diode. Solar with Auto D-TEC watches the light and pulls power from the panel or the CR2032 as needed. Side-load battery, so you are not pulling the optic to change it.
