5x fixed magnification. Great power to make hits out to 600 yards or for close quarters using both eyes open. Red or green lit Ballistic/CQ reticle that is very easily visible in bright sunlight. Reticle is also etched on glass so if battery dies you still have a usable sight. Fits on any picatinny rail. Has small sections of rail on the sight itself if you want to add a Fast Fire or any other micro red dot to the top it. Burris also has their awesome Forever Warranty if you ever have any issues with it; they fix it or replace it no questions asked. The attached YouTube videos are of the actual sight in use. Excellent shape and super clear glass, but no box or manual. Sells for $380-$400 new. Asking $250 obo or trade for Ruger LCP, Mossberg 500/590, or a good red dot.
