Swampfox Optics Blade 1X25Mm Amber Brc Prism Sight Black
The Swampfox Optics Blade 1x25mm prism sight is a fixed-magnification optic purpose-built for shooters who need speed and accuracy at close quarters—home defense, tactical training, and law enforcement work. Unlike traditional red dot sights, the Blade's prism design with etched reticle makes it an excellent choice for shooters with astigmatism, since the reticle stays crisp and defined whether the illumination is on or off. The amber Bullet Rise Compensating (BRC) reticle is specifically calibrated to simplify aiming on AR-platform rifles at the distances where home defense matters most: 5, 10, and 15 yards. This cuts the guesswork out of quick, defensive shooting.
Built for real-world use, the Blade features Auto-On Shake N' Wake technology that activates the illumination when you move the gun, so you're ready to go the instant you need to be. The reticle appears black when the illumination is off, giving you a clean aiming point in daylight or low-light conditions. With a 3.8-inch eye relief, the Blade works well on rifles where you need to stay behind the gun without being glued to the scope. Its compact 1x magnification keeps your field of view wide and your target acquisition lightning-fast—no magnification to slow you down in a fight.
If you've struggled with astigmatism and dot sights, or if you want a dedicated close-range optic that doesn't rely on a fragile electronic dot, the Blade delivers the optical clarity and mission-ready features that Swampfox built it for.

The Bullet Rise Compensating reticle is calibrated for 5, 10, and 15-yard distances when mounted on an AR-15 platform, making it ideal for home defense and close-quarters tactical applications.
Does the Blade work in daylight without illumination?
Yes. The etched amber reticle appears black when the illumination is off, so you have a clean, usable aiming point in daylight. The Auto-On Shake N' Wake feature activates illumination automatically when you move the gun, ensuring the optic is ready when you need it.

The Blade has 3.8 inches of eye relief, which is comfortable for AR-platform rifles and allows you to maintain proper shooting position without being forced into an awkward cheek weld.
