Red Dot Sights have their origin in aircraft gunsights or 'collimators' where the shooter's reticle is projected on a clear lens/glass pane allowing for easier target acquisition and a clearer sight picture of a target, later adapted for smalls arms rifles, red dots exist to be incredibly sturdy, and reliable open sight picture 'optics'. Red Dot Sights(RDS) allow for faster target acquisition due to their wide-open glass nature and feature almost unlimited eye relief as the projected reticle is reflected off of the glass and back into the shooter's eye. meaning you can see your point of aim from almost anywhere on a rifle or pistol. The AR-15 platform was adapted for use with these aiming systems back in the late 80s when the carry handle was being sidelined in favor of the distinct Flat-Top / Picatinny rail system.
About this Sight System: The next generation ultra-compact micro red dot sight optimized for everyday carry-on slimline pistol slides. No plastic body or polymer lens for us only hard-coated 7075 aluminum and multi-coated glass here. Sentinel-A truly never sleeps. A photosensitive sensor on the left side of the scope body provides a bright dot relative to ambient light in all conditions, day or night. There are no manual controls at all, no Shake N Wake no way for Sentinel-A to be accidentally shut off, ever. Install the CR2032 battery underneath Sentinel-A and you're good to go for two years straight.

Reticle Type: This site uses a 3 MOA Red Dot reticle.
Battery Type: The Swampfox Sentinel uses a CR2032 small form factor battery to keep it powered at all times for 2 years straight.
